量子计算是21世纪物理学研究的前沿方向之一,量子加速性在计算中的实现主要基于叠加和纠缠性等量子特性,构建量子计算机的备选系统包括光子、离子阱、量子点和超导约瑟夫森结等.相比于其他量子系统,超导系统与环境的耦合更强,拥有无可比拟的可控制性和可扩展能力,更有希望实现大规模集成的量子计算芯片.浙江大学物理系王浩华研究组使用基于超导约瑟夫森结的量子芯片作为量子加速能力实现的物理载体,联合国内相关单位自主设计制备了高性能超导量子芯片,掌握了国际领先的多比特调控测量技术.1982年,美国物理学家费曼提出利用可控量子系统实现量子模拟.量子系统通常由很多粒子(即量子比特)组成,用处于系统希尔伯特空间
Quantum computation is one of the frontier directions in physics research in the 21st century. The realization of quantum acceleration is mainly based on quantum properties such as superposition and entanglement. The alternative systems for constructing quantum computers include photons, ion traps, quantum dots and superconductors Josephson junction, etc .. Compared to other quantum systems, the superconducting system coupled with the environment stronger, has unparalleled controllability and scalability, more promising large-scale integrated quantum computing chip.Zhejiang University physics Department of Wang Haohua research group based on the superconducting Josephson junction quantum chips as a quantum carrier to achieve physical acceleration of the carrier, the relevant domestic units independently designed and prepared high performance superconducting quantum chips, mastered the world’s leading multi-bit control technology .1982 In ‧ feynman, an American physicist, proposed the quantum simulation using a controlled quantum system, which usually consists of many particles (ie, quantum bits)
