        NIST announced the first batch of algorithms to be standardized in July, as well as other algorithms to be analyzed during the fourth round. Among them, Sike is the algorithm selected for further research in the fourth round, which is a key encapsulation (KEM) algorithm. Researchers from the University of Leuven in Belgium said that they were able to find a valid key recovery attack of sikep434 with security level 1 using a single core processor through the magma program in about one hour. Sometimes, the defect can be solved by minor modification of the algorithm, but if it cannot be repaired, the Sike algorithm will no longer be considered as a post quantum standard algorithm.
 
        On August 4, berkemer Clayton, a senior headhunting company, announced the establishment of an independent department & mdash& mdash; Psirch is committed to providing services to the quantum technology industry, its strategic partners and companies seeking early use of quantum technology. With its new Department, berkemerclayton also aims to become an active force in the "quantum women" movement, which has received considerable support. Researchers at the Massachusetts Institute of Technology (including Peter shor) and Harvard University have found a way to create a quantum currency that can be verified by anyone, making it completely decentralized, and no blockchain is required to record transactions securely.
 
        The security of this new method comes from a form of post quantum encryption that can resist the attack of quantum computer. The method is to encode a random lattice into a quantum property of a quantum currency unit, perhaps an atomic array. Anyone who wants to copy this fund must copy this random grid. But this can only be done when the shortest vector is known. This task cannot even be completed by a quantum computer. This ensures the security of funds and is easy to verify because the quantum state of the lattice has specific properties that can be tested by any user. All this is done by the buyer and the seller without any transaction records. Ownership verification can be completed locally and offline, without global synchronization through blockchain and other mechanisms.
 
        The scientific team of quantum, a quantum computing company under Honeywell, reported an important research progress, which showed that logical qubits can outperform physical qubits, demonstrated the entanglement gate between two logical qubits for the first time, and used real-time error correction in a completely fault-tolerant manner. This is also the first time to show a logic entangled circuit with higher fidelity than the corresponding physical circuit. This demonstration provides a way to achieve scalability, qubit efficiency, and fault tolerance with fewer circuits. The team described and compared two different implementations of fault-tolerant entanglement gates on logical qubits. In the first case, they used a 12 qubit trapped ion quantum computer and realized a non lateral logic CNOT gate between two logic qubits using quantum error correction codes.
 
        In the second case, a horizontal logic CNOT gate is implemented on two logic qubits using a 20 qubit trapped ion quantum computer. These two codes are implemented on different but similar devices. In both cases, all quantum error correction primitives, including determining correction by decoding, are implemented at runtime using a classical computing environment that is tightly integrated with quantum processors. This study demonstrates the application of multiple rounds of quantum error correction to a single logical qubit. The first atomic quantum computing cloud platform in China & mdash& mdash; On the day when "KuYuan quantum cloud" will be launched, the reporter learned from Wuhan Institute of quantum technology that the first atomic quantum computing cloud platform in China & mdash& mdash; "KuYuan quantum cloud" will be launched soon. Users can connect the server through the Internet, simulate the atomic quantum computer, and feel its unique computing power.
 
        It is expected that the first 100 + bit atomic quantum computing prototype in China will be released at the end of this year. Users can conduct various scientific and Application Research Based on the real atomic system on the cloud platform without simulation. This is a major achievement made by Wuhan Institute of quantum technology and Zhongke KuYuan Technology (Wuhan) Co., Ltd. in accelerating the in-depth integration of industry, University and research, and increasing the key core technology research. "The 100 + bit atomic quantum computing prototype developed by Zhongke KuYuan has reached the international first class in terms of indicators." Researcher Zhan Mingsheng, vice president of Wuhan Institute of quantum technology and chief scientist of Precision Measurement Institute of Chinese Academy of Sciences, introduced that universities, scientific research institutes and enterprises can carry out scientific research on this platform and share the convenience brought by advanced achievements.
 
        Through the "cloud platform", users can verify ideas or optimize algorithms on real physical qubits, study novel physical states, and explore the boundaries of science. On July 27, the US Senate passed the chip bill with a scale of about 280 billion US dollars by 64 votes to 33. In addition to providing subsidies to the semiconductor industry, the bill also has a large amount of funds to be used for research and development in frontier scientific and technological fields such as quantum computing. This includes injecting new funds into national laboratories of the Ministry of energy such as Brookhaven National Laboratory, which will promote research and development, including quantum computing, artificial intelligence and other key technology fields. John Burke, chief director of quantum science of the office of the Deputy Secretary of research and engineering of the US Department of defense, pointed out at the executive biz quantum technology forum that since 1990, the Department of defense has been pursuing the layout of quantum information science.
 
        Although a lot of publicity has been made around this technology, many components constituting the ultramodern system are still in the initial stage, and the realization of quantum success will largely depend on public-private partnerships, because the development of different centers may require professional platforms that work together with the development of technology. Burke also pointed out that there is uncertainty about the financing in the near future and in the future. Hcltechnologies, the world's leading technology company, signed a memorandum of understanding (MOU) with the Sydney quantum Institute (SQA) to help accelerate the development of the quantum technology ecosystem in Australia. SQA is composed of Macquarie University, the University of New South Wales, the University of science and technology of Sydney and the University of Sydney, and is supported by the government of New South Wales. Its vision is to establish Australia's quantum economy.
 
        Through this industry university cooperation, it creates education and development opportunities for students in the field of quantum technology, and connects HCl's diversified and large customer base with the growing Sydney quantum community. HCl is helping enterprises and partners to take advantage of the emerging opportunities brought by quantum technology by preparing an innovative ecosystem. SQA's program aims to develop the expertise and labor force needed to provide these future applications and help enterprises prepare for emerging technologies. Mou provides a platform for HCl and SQA to explore opportunities to build capacity and awareness. By 2025, a team of 11 researchers from the University of Nuremberg (Fau) will receive about 3 million euros as part of the Munich quantum Valley project to promote quantum science and quantum technology in the free state of Bavaria.
 
        Its project "quantum measurement and control for quantum computing and quantum sensing (qumeco)" will set off a wave of basic research on quantum computing, sensing and imaging, and combine physics and electrical engineering in a new way in the field of light and matter. Qumeco combines Fau's unique expertise in light and physical physics with its expertise in electrical engineering. One of its goals is to lay the foundation for the next generation of superconducting quantum computers. The research team will develop microwave circuits as close to quantum chips as possible. An innovative laboratory will also be established in Erlangen to characterize such circuits at very low temperatures.
 
        In addition, researchers are experimenting with new quantum light sources and detectors, and using the special characteristics of entangled photons to study new technologies. They also use color centers as highly sensitive quantum sensors to depict the electric and magnetic fields and the electrochemical and photochemical reactions of molecules at a new optical resolution level. A new project of the University of Warwick and University College London aims to answer a basic question of quantum physics, trying to make a diamond exist in the superposition of two positions at the same time. The project received a grant of £ 500000 from the UK science and Technology Facilities Council from its quantum technology for basic physics program. Recently, the research team of Yokohama National University in Japan demonstrated the control of quantum bits by using the nitrogen vacancy center in diamond to manipulate the electron spin by combining microwave manipulation and local optical shift of atomic and molecular transition frequencies. They were able to combine laser dependent optical methods with microwaves to overcome previous limitations.
 
        The research results were published in the journal Nature photonics with the title of optically addressable universal complete quantum gate on Diamond spin. Researchers can also prove that this control of the electron spin can in turn control the nuclear spin of the nitrogen atom in the nitrogen vacancy center and the interaction between the electron and the nuclear spin. This indicates that the qubits can be precisely controlled without wiring problems. This paves the way for large-scale quantum processors and quantum memories, and helps to develop large-scale quantum computers. In addition, researchers can generate quantum entanglement between electrons and nuclear spins, which allows connection between quantum bits and photons, and ultimately requires less computing power, and can transmit information to quantum processors and quantum memories through the principle of quantum teleportation.
 
        This method meets all the divicenzo standards, which are required for the operation of quantum computers, including scalability, initialization, measurement, general gate and long coherence. It can also be applied to other magnetic field schemes other than the stark offset to manipulate qubits individually in these scenarios, and can prevent common types of computational errors, such as gate errors or environmental noise. On August 2, the quantum algorithm company phasecraft announced that it has received two research grants from the UK research and innovation department (ukri), which is part of the challenge of commercialized quantum technology provided by innovateuk (the "innovation UK" project of the UK Technology Strategy Committee).
 
        Phasecraft will cooperate with British Telecom and rigetticomputing, a quantum computing company, to lead a funding project, focusing on the development of recent quantum computing to solve hard optimization problems and constraint satisfaction problems, including computing problems in a series of fields including network design, electronic design automation, logistics and scheduling. These problems are characterized by the need to find a solution among the potential solutions that have multiplied. Rigetti computing, a subsidiary of quantum computing company, was selected by DARPA to develop a performance benchmark for quantum applications on large-scale quantum computers. The University of science and technology of Sydney, the University of Alto and the University of Southern California participated in the project together with rigetti.
 
        The team will receive $2.9 million over three years, but certain milestones must be reached. Recently, the source quantum research and development team and Professor Zhang Junliang of Fudan University cooperated to design a new molecular crystal structure prediction algorithm by using the parallel computing ability of quantum superposition states, which proved that quantum computing can help chemists predict the molecular structure of crystals with a more accurate formula than traditional modeling methods. The original quantum team used the quantum approximate optimization algorithm (qaoa) to accelerate the selection of the global minimum dipole energy sum at the square level. By coding the problem as a combinatorial optimization problem, it paved the way for solving the problem of molecular crystal structure prediction.
 
        The team also adopted a variant of qaoa called quantum alternating operation algorithm. By selecting appropriate initial quantum states and quantum operations, it ensured that the final result would be in the feasible solution space without adding penalty terms. This method not only gets rid of the difficulty of super parameter selection, but also greatly improves the optimization efficiency. In addition, the team successfully constructed the required initial quantum state without using additional quantum bits. Through the XY mixed layer, only the% optimal solution probability of two layers of qaoa line is used to successfully obtain the same result as the classical ergodic method in the nitrofurazone crystal data.
 
        The researchers also additionally compared the performance of the two implementations of the XY hybrid layer (complete and ring) and the traditional qaoa hybrid layer (x). The horizontal axis in the figure above is the number of quantum gates. It can be seen that at the same number of quantum gates, the effect of the XY hybrid layer is much better than the traditional qaoa algorithm. In the future, Benyuan quantum team and Fudan University will continue to carry out cooperative exploration in this field, and realize the landing of quantum algorithms on noisy quantum chips through technical research on parameter optimization methods, coding methods, and quantum circuit layout. It will further provide online SaaS drug design preliminary screening, drug efficacy evaluation and other modules, and realize online prediction of drug molecular crystal structure and lattice energy, Promote the application of quantum computing in biomedicine.
 
        Advanced quantum testing platform (AQT) of Lawrence Berkeley National Laboratory and quantum computing software company super Tech's research partners showed how to optimize the implementation of the zzswap network protocol. The team also introduced a new technology for reducing quantum errors, which will improve the implementation of network protocols in quantum processors. The experimental data were published in the physical review research, which added more ways to realize quantum algorithms using gate based quantum computing in the short term. The research partner used super Tech's superstaq software enables scientists to finely customize their applications and automatically compile the circuits of AQT's superconducting hardware, especially the native high fidelity controlled s-gates that are not available for most hardware systems.
 
        This intelligent compilation method with four transmission qubits allows the swap Network to be decomposed more efficiently than the standard decomposition method. Zzswap gate network only needs the minimum linear connection between qubits without additional coupling. Therefore, it provides practical advantages for efficient implementation of quantum algorithms, such as quantum approximate optimization algorithm (qaoa). Its technology has been experimentally verified on the advanced quantum test bench by executing qaoa circuit to find the ground state of the two node and four node Sherrington Kirkpatrick spin glass model with various random sampling parameters. It is observed that the error of qaoa with depth P = 1 is reduced by 60% on average on the four transmission qubits on the superconducting quantum processor.
 
        Quantum's research team has designed a simulation algorithm to enable quantum computers to simulate an infinitely long chain of interacting electron like particles with very few qubits. The researchers used qubits made of charged ytterbium atoms and programmed them to run a new algorithm that simulates a chain of interacting particles. The researchers benchmarked this holographic technique in the capture ion quantum processor, which uses 11 qubits to simulate the dynamics of infinitely entangled states. They observed the characteristics of quantum chaos and correlated light cone propagation, and found that there was excellent quantitative consistency with the theoretical prediction of realizing the infinite size limit of the model, and there was minimal post-processing or error mitigation.
 
        In collaboration with the National Institute of standards and Technology (NIST) and the Joint Laboratory of Astrophysics (Jila), the research team demonstrated for the first time that a new miniaturized version can be used
