而IBM所公布的50量子比特计算机是什么呢？这个要从量子计算器讲起。量子计算机（quantum computer）是一类遵循量子力学规律进行高速数学和逻辑运算、存储及处理量子信息的物理装置。早先由理查德·费曼提出，一开始是从物理现象的模拟而来的。可他发现当模拟量子现象时，因为庞大的希尔伯特空间使资料量也变得庞大，一个完好...

Our first achievement has been accomplished on the IBM Q quantum computer available for use through the IBM Q Experience online platform and the Qiskit open-source quantum software development kit, which forms a virtual interface for the quantum computer. Our second realization uses the Feynman, ...
IBM Quantum System Two 此刻,在纽约威彻斯特郡的一栋大楼大厅外,一间简陋的会议室里,世界上最大的量子计算机系统安静地嗡嗡作响。 这座建筑就是托马斯-J-沃森研究实验室(Thomas J. Watson Research Lab),曾诞生现代激光器、DRAM、曼德布罗特集、国际象棋计算机“深蓝”以及协助宇航员登月的一系列产品。
Late last year, IBM took the record for the largest quantum computing system with a processor that contained 433 quantum bits, or qubits, the fundamental building blocks of quantum information processing. Now, the company has set its sights on a much bigger target: a 100,000-qubit machine...
近日,谷歌据传实现“量子霸权”(quantum supremacy) 的消息引发轰动。事件目前还在持续发酵,现已出现了包括 IBM 量子计算专家在内的“质疑派”。 事情的起因是,据英国《金融时报》9 月 20 日报道,一篇证明谷歌实现“量子霸权”的论文在 NASA 艾姆斯研究中心 (Ames Research Center) 网站上短暂发表,该中心的一些研究...
Simulating the behaviour of complex quantum systems is impossible on classical supercomputers due to the exponential scaling of the number of quantum states with the number of particles in the simulated system. Quantum computers aim to break through this limit by using one quantum system to simulate...
量子计算研究的终极目标之一是制造并应用通用量子计算机(Universal Quantum computer)。以当前的设计构想,至少要能够处理上百量子比特位(qubit)才有意义,目前IBM开放的5-qubit计算服务离这一目标还差得很远。通用量子计算机的具体指标可以参考《The Physical Implementation of Quantum Computation》(http://arxiv.org/abs...
