谷歌公布的另一个进展,“random circuit sampling”跑5分钟相当于经典计算机10亿亿亿年,这肯定是炒作,业界人士其实是不满的。——这个不是炒作,它说的其实就是量子优越性,即量子计算机在某个数学问题上超过最强的经典计算机。只不过这不是个新成就,因为2019年的悬铃木和2020年的九章做的就是这个,数学问题都是随机...
phase transition controlled by the error per cycle; to identify it analytically and experimentally, we create a weak-link model, which allows us to vary the strength of the noise versus coherent evolution. Furthermore, by presenting a random circuit sampling experiment in the weak-noise phase wit...

Random quantum circuit sampling is proposed as the most promising approach to the task and has been implemented in experiments for achieving quantum advantage. A series of encouraging computational complexity results, based on some plausible assumptions, show that this task is impossible t...
60-Qubit random circuit sampling After the basic calibration, we implement random quantum circuit sampling to characterize the overall performance of the quantum processor, and measure the degree of quantum computational advantage. The gate sequence of our random quantum circuit is shown in Fig. 3a....

The invention relates to a random sampling analog circuit compressed sensing measurement and signal reconstruction method, which belongs to the field of electronic system test and fault diagnosis. Aiming at a fault signal having a sparsity distribution characteristic per se or in an orthogonal space in...
Building on this, we develop a quantum analogue of these classical algorithms using a quantum circuit model for random sampling of permutations for n n -qubit systems. As an application, we present a quantum algorithm for the two-sample randomization test to assess the difference of means in ...
