BEIJING , Dec. 26, 2024 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WiMi) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of a Quantum Technology-Based Random Access Memory Architecture, known as QRAM. This architecture successfully implements fundamental logical operations such as AND, OR, NOT, and NOR gates in quantum logic gates by combining key basic operations in quantum computing, such as the CNOT gate, V gate, and V+ gate. Quantum Random Access Memory (QRAM) is a memory architecture specifically designed for quantum computing environments, with the core goal of enabling efficient reading and writing of information while maintaining the state of the quantum system. The design of QRAM is not only intended to leverage the parallel processing capabilities of quantum computing but also to utilize quantum properties such as superposition and entanglement to significantly enhance computational efficiency. In WiMi's QRAM architecture, the quantum CNOT gate, V gate, and V+ gate serve as the fundamental operation units. Each quantum operation is equivalent to certain logical operations in classical computing, but simultaneously leverages the properties of quantum states to achieve efficient computation. CNOT Gate (Controlled-NOT Gate): The CNOT gate is a crucial operation in quantum computing, used to control the relationship between two quantum bits (qubits). In classical computing, this is similar to the function of an XOR gate, but in the quantum environment, it allows qubits to exist in a superposition of states, enabling the simultaneous processing of multiple states. V Gate and V+ Gate: The V gate and V+ gate are quantum gates used to implement more complex logic. The operations of these two gates are similar to the AND and OR gates in classical computing. However, their advantage lies in the ability to process multiple potential outcomes in the quantum system simultaneously, without the need to evaluate each possibility separately. By combining these fundamental quantum gates, basic operations in quantum logic such as AND, OR, NOT, and NOR can be successfully implemented. This provides the necessary support for designing complex quantum circuits, while being more flexible and efficient compared to classical logic gates. One of the major advantages of the QRAM architecture is its full utilization of the properties of quantum superposition and quantum entanglement. In classical computing, memory read and write operations are linear and must be performed sequentially. However, in quantum computing, because qubits can exist in multiple states (superposition), parallel read and write operations can be performed simultaneously. This ability significantly enhances computational efficiency, especially when handling large-scale datasets or complex computational tasks. Additionally, quantum entanglement enables the correlation between multiple qubits without the need for direct communication, further improving the speed of data transfer and computation. Memory operations with entangled qubits are much faster and more efficient than traditional memory operations, opening up new possibilities for parallel computing. In WiMi's QRAM architecture, the entire design logic includes several key steps and technical nodes, such as quantum state-based random access, the introduction of quantum error correction mechanisms, and seamless integration with quantum computers. The core feature of QRAM is its ability to perform random access within a quantum system. Traditional computer RAM achieves reading and writing to memory units through address buses, data buses, and other components, whereas QRAM accomplishes this process through the states of quantum bits (qubits). By utilizing quantum superposition, multiple addresses can be accessed simultaneously in a single operation. This means that in a QRAM system, data can be accessed in parallel across multiple addresses, greatly improving the efficiency of data operations. To achieve this, WiMi has designed a system based on CNOT gates, V gates, and V+ gates. These quantum gates allow flexible control over memory access processes while maintaining the quantum state of the system and ensuring the efficient transmission of qubits in an entangled state. Through this system, QRAM not only enables high-speed data reading and writing, but also ensures the reliability and accuracy of information processing. Furthermore, error correction is crucial in any quantum computing system. Due to the fragile nature of qubit states, even small external disturbances can cause computational errors. Therefore, WiMi's QRAM architecture incorporates a quantum error correction mechanism to ensure that the qubit states are accurately preserved and transmitted during data reading and writing. This includes an error correction method based on quantum entanglement, where redundant entangled qubits are introduced to detect and correct potential errors. This method not only effectively reduces the impact of external noise on the system but also ensures the stability of data during multiple read operations. WiMi's QRAM design is intended to seamlessly integrate with quantum computers. Since quantum computing operations depend on the superposition and entanglement states of qubits, the QRAM system demonstrates high compatibility when interfacing with a quantum processing unit (QPU). The design ensures smooth transmission of qubits between memory and processor during data access, thereby significantly improving computational efficiency. By utilizing the V gate, V+ gate, and CNOT gate, WiMi's QRAM system can quickly execute quantum logic operations and, when handling complex computational tasks, can read and write data at near-real-time speeds. This makes QRAM a key component in large-scale quantum computing applications. The successful development of QRAM technology has had a revolutionary impact across multiple fields. As a critical component of quantum computers, QRAM will significantly enhance the overall performance of quantum computing systems. Its efficient parallel data access capabilities make it especially well-suited for handling large-scale computational tasks such as molecular simulations, climate modeling, and complex optimization problems. By significantly reducing computation time, QRAM will play an indispensable role in the future of high-performance quantum computing. Another important application of QRAM is in quantum communication and quantum encryption. By leveraging quantum entanglement, QRAM can enable high-speed data transmission while ensuring data security. The non-locality of quantum entanglement guarantees that data cannot be intercepted during transmission, providing a solid foundation for future quantum encryption technologies. With the development of quantum computing, the field of quantum machine learning has also gradually emerged. QRAM's efficient data access capabilities make it highly suitable for handling large-scale datasets, enabling model training to be completed in a shorter time. This will significantly advance the development of quantum artificial intelligence, allowing complex machine learning tasks to be solved quickly on quantum computers. As quantum technology continues to evolve, QRAM, as a core technology, will provide crucial support for the future of quantum computing. WiMi is committed to continuing the development of QRAM technology, continually optimizing its performance, reducing implementation costs, and expanding its applications across various industries. The successful development of QRAM technology marks an important step in the advancement of quantum computing. As quantum computers progress and quantum technologies mature, QRAM will become an indispensable core component of quantum computing systems. With the ongoing optimization and promotion of this technology, QRAM is expected to bring disruptive innovations across multiple fields and lay a solid foundation for the arrival of the quantum era.

Rocket Lab ( RKLB 6.15% ) stock spent most of Christmas week opening presents from its PR department, which posted on X about how well things went for the company in 2024 -- 16 rocket launches, a growing business providing solar power panels for spacecraft, and an accelerating cadence of rocket launches in the year's final weeks. How fast will Rocket Lab grow in 2025? Of all these announcements, I imagine it's this last one that most excited investors in the rocket stock . And why? It's not just the growth from 10 rocket launches in 2023 to 16 in 2024 that gets me. It's that over the last four weeks, Rocket Lab launched four times. Admittedly, rocket businesses are "lumpy." Bad weather, technical glitches, and wayward boats in the launch zone can scramble schedules, causing a dearth of launches in one month and making launches bunch up in the next. Still, if Rocket Lab launched four rockets in four weeks in November and December, it should, at least in theory , be able to sustain a launch-a-week cadence. And if Rocket Lab can find enough customers, this implies that 2025 could see many more launches than we saw in either 2023 or 2024. Is Rocket Lab stock a buy? How often might Rocket Lab launch in 2025? In theory , at its present pace, it could launch 52 times. At an average launch cost of $8.2 million, this suggests Rocket Lab's launch services division could generate $426 million in annual revenue -- more if some of these launches are of Neutron rockets costing up to $55 million a pop. And that would be incredible growth compared to the launches' $72 million in 2023 revenue. Sure, all this is in theory, but it's still more than enough to get Rocket Lab investors excited today.
TORONTO — With Jan. 27 marking 500 days out from the 2026 World Cup kickoff, some 50-plus staff are fleshing out the Canadian end of the tournament at FIFA's Toronto office. The office has been around for a year, although it took six months to get it to where it is now — a fully functioning space with more than a little character. The entrance features a display of 14 official match balls dating back to the 1970 World Cup. A giant 2026 cut-out in the shape of the FIFA World Cup trophy provides a unique photo op. Maple Leaf motifs decorate the converted factory, which is getting busier by the day. Peter Montopoli, chief tournament officer for the Canadian end, says the staff numbers will soon reach 80, with another 600 to 700 involved during the event itself. A lot has happened since Montopoli, then Canada Soccer's general secretary, and Victor Montagliani, then Canada Soccer's incoming president, hashed out the idea of bidding for the men's World Cup at a 2011 dinner at a Vancouver restaurant with Walter Sieber, director-general of sports at the 1976 Montreal Olympics and a man plugged into the world governing body of soccer. "When we announced in May 2012 ... it wasn't actually accepted very well by a few journalists in this city, who kind of laughed at it and scoffed at it," said Montagliani, who still keeps one of those negative articles in his desk. Montagliani, now president of CONCACAF and a FIFA vice-president, looks forward to the 2026 tournament — an expanded 48-team, 104-game colossus co-hosted by Canada, the United States and Mexico — and its legacy. He calls it a "seminal moment ... that I think is going to push the game to the next level." "What I see is (that) '26, quite frankly, is really the beginning of the next era for the game in our country. It's not the culmination of it," Montagliani told a media roundtable Monday. "Hosting a World Cup is like nothing any of us (know). I don't even think I know what it's going to be like. And I've put on a few of these things. And I still don't know. I think I'm underestimate the impact this (tournament) is going to be. And if I'm underestimating, the person on the street is underestimating it too." Staff at the Toronto office are working on everything from stadium and venue operations, and safety and security to commercial, legal, finance and government relations. They work in conjunction with FIFA offices in Miami and Mexico as well as the FIFA head office in Zurich. Canada and Mexico, which has three host cities to Canada’s two, will each host 13 matches with the U.S. staging the remaining 78 across its 11 host cities. Toronto and Vancouver will each host five opening-round matches plus a round-of-32 knockout match. Vancouver will also stage a round-of-16 game. FIFA plans to open a tournament office in Vancouver in the second quarter of 2025. Both Canadian offices will be walking distance to their local venues: Toronto's BMO Field and B.C. Place Stadium. Montopoli and his staff have a detailed timeline, covering everything from the tournament draw to unveiling of mascots, official songs and posters. FIFA is encouraging fans interested in tournament tickets to register via FIFA.com. Hospitality packages are already open and other packages are expected next September, with single-game tickets to follow after the draw in early December 2025. There is much to be done, starting with the two Canadian host stadiums. A ring of permanent suites is under construction at B.C. Place. BMO Field will get an additional 17,750 seats, bringing total capacity to around 45,735 seats, with the north and south ends expanded. Not all the new seats will be permanent, but some of the new suites at BMO Field will be. Montopoli says his staff are working with the City of Toronto, which owns the stadium, and Maple Leaf Sports & Entertainment, which manages the facility, to decide what upgrades will permanent. "They're still in discussion with that, because they still have to work through the economics of it" he said. Improvements include new video boards. And while some of the expanded BMO stands will be temporary, the additions will be proper seats not benches. Montagliani says every stadium among the 16 host cities is getting upgrades, even AT&T Stadium in Arlington, the US$1.2-billion-dollar home of the Dallas Cowboys. Vancouver has already announced its tournament training facilities will be at Killarney Park and Memorial South Park once upgrades are complete. While Toronto has yet to confirm its training venues, with fields at Etobicoke’s Centennial Park one option, Montopoli says they will be finalized in the first quarter of 2025. FIFA's Miami-based tournament traffic lead is currently visiting the city, a "world-class expert" who has done World Cups, Olympic Games and the 2015 Pan-American Games in Toronto, said Montopoli. "She's fully aware of everything, Toronto's transport issues," he added. Fans can expect a much different landscape around the stadiums than normal, with an expanded secure zone. "This is not the Grey Cup. This is the World Cup and it's going to be completely different from an operational logistical standpoint, logistical standpoint, than anything we've ever experienced," Montagliani said. And while holding a tournament in 16 host cities and three countries is vastly different from the 2022 tournament in Qatar, which had all eight stadiums in and around the capital of Doha, Montagliani says a lot of FIFA's World Cup blueprint can be transferred. "A venue is a venue is a venue," he said. Teams will have their own base camps during the group stage with nearby cities grouped in clusters. Toronto, for example, is linked to Philadelphia, Boston and New York, while Vancouver is grouped with Seattle, San Francisco and Los Angeles. --- Follow @NeilMDavidson on X platform This report by The Canadian Press was first published Dec. 8, 2024.

While Berlin and other governments said they were watching the fast-moving developments in the war-ravaged nation, Austria signalled it would soon deport refugees back to Syria. Far-right politicians elsewhere made similar demands, including in Germany -- home to Europe's largest Syrian community -- at a time when immigration has become a hot-button issue across the continent. Alice Weidel, of the anti-immigration Alternative for Germany, reacted with disdain to Sunday's mass rallies by jubilant Syrians celebrating Assad's downfall. "Anyone in Germany who celebrates 'free Syria' evidently no longer has any reason to flee," she wrote on X. "They should return to Syria immediately." World leaders and Syrians abroad watched in disbelief at the weekend as Islamist-led rebels swept into Damascus, ending Assad's brutal rule while also sparking new uncertainty. A German foreign ministry spokesman pointed out that "the fact that the Assad regime has been ended is unfortunately no guarantee of peaceful developments" in the future. Germany has taken in almost one million Syrians, with most arriving in 2015-16 under ex-chancellor Angela Merkel. Interior Minister Nancy Faeser said many Syrian refugees "now finally have hope of returning to their Syrian homeland" but cautioned that "the situation in Syria is currently very unclear". The Federal Office for Migration and Refugees had imposed a freeze on decisions for ongoing asylum procedures "until the situation is clearer". She added that "concrete possibilities of return cannot yet be predicted and it would be unprofessional to speculate in such a volatile situation". Rights group Amnesty International slammed Germany's freeze on asylum decisions, stressing that for now "the human rights situation in the country is completely unclear". The head of the UN refugee agency also cautioned that "patience and vigilance" were needed on the issue of refugee returns. In Austria, where about 100,000 Syrians live, conservative Chancellor Karl Nehammer instructed the interior ministry "to suspend all ongoing Syrian asylum applications and to review all asylum grants". Interior Minister Gerhard Karner added he had "instructed the ministry to prepare an orderly repatriation and deportation programme to Syria". "The political situation in Syria has changed fundamentally and, above all, rapidly in recent days," the ministry said, adding it is "currently monitoring and analysing the new situation". The French interior ministry said it too would put asylum requests from Syrians on hold, with authorities in Belgium, the Netherlands, Switzerland, Denmark, Sweden and Norway announcing similar moves. Britain's interior ministry said it was taking the same measure "whilst we assess the current situation". The Italian government said late Monday after a cabinet meeting that it too was suspending asylum request "in line with other European partners." The leader of the far-right Sweden Democrats, a coalition partner in the government, said residence permits for Syrian refugees should now be "reviewed". "Destructive Islamist forces are behind the change of power" in Syria, wrote their leader Jimmie Akesson on X. "I see that groups are happy about this development here in Sweden. You should see it as a good opportunity to go home." In Greece, a government spokesman voiced hope that Assad's fall will eventually allow "the safe return of Syrian refugees" to their country, but without announcing concrete measures. In Germany, the debate gained momentum as the country heads towards February elections. Achim Brotel, president of a grouping of German communes, called for border controls to stop fleeing Assad loyalists reaching Germany. The centre-right opposition CDU suggested that rejected Syrian asylum-seekers should now lose so-called subsidiary protection. "If the reason for protection no longer applies, then refugees will have to return to their home country," CDU legislator Thorsten Frei told Welt TV. CDU MP Jens Spahn suggested that Berlin charter flights to Syria and offer 1,000 euros ($1,057) to "anyone who wants to return". A member of Chancellor Olaf Scholz's Social Democrats criticised the debate as "populist and irresponsible". Greens party deputy Anton Hofreiter also said "it is completely unclear what will happen next in Syria" and deportation talk was "completely out of place". Many Syrians in Germany have watched the events in their home country with great joy but prefer to wait and see before deciding whether to return. "We want to go back to Syria," said Mahmoud Zaml, 25, who works in an Arabic pastry shop in Berlin, adding that he hopes to help "rebuild" his country. "But we have to wait a bit now," he told AFP. "We have to see what happens and if it is really 100 percent safe, then we will go back to Syria." burs-fz/rlp/phz/gv/giv
