日本将开发最先进的超导量子计算机

Core Viewpoint - Fujitsu is collaborating with RIKEN to develop a new quantum computer that aims to achieve the world's highest computational power, with approximately 250 logical qubits, surpassing IBM's model by 25% expected to be completed by 2029 [1][2]. Group 1: Development and Technology - Fujitsu's new quantum computer will utilize superconducting technology, which involves cooling devices to extremely low temperatures to eliminate resistance [1][2]. - The company is transitioning from relying on overseas suppliers for key components like cryogenic machines to using domestic Japanese manufacturers, with IHI and Taiyo Nippon Sanso as potential partners [1][2]. - Fujitsu is optimizing the wiring of micro-components and control devices to enhance performance while maintaining compactness within a single cryogenic machine [2]. Group 2: Performance and Efficiency - The quantum computer developed using the STAR architecture in collaboration with Osaka University is expected to complete a task that currently takes five years on a supercomputer in about 10 hours [2]. - Fujitsu is focusing on both hardware and software advancements to surpass the computational speed of competing products, while also addressing energy efficiency and manufacturing cost reduction [2]. Group 3: Market and Applications - Quantum computers are anticipated to drive significant technological transformations across various industries, including drug development, new material research, finance, and electric vehicles (EVs) [3]. - The global quantum computing market is expected to expand alongside related industries as practical applications progress [3]. - The Japanese government is supporting the development of domestic quantum computers, with Fujitsu set to receive approximately 10 billion yen in subsidies from the New Energy and Industrial Technology Development Organization (NEDO) [3].
