论文摘要
在制造非音量的超导通路电路中存在极大的兴趣 - 即，在其Qubit表示中具有积极的偏置基矩阵元素 - 因为这些电路被认为是不可模拟的，因此可以通过经典的方法进行启动，并且可以在量子量化协议中的快速中发挥关键作用。但是，我们表明，通过直接模拟通量电路可以对这些系统进行有效的仿真。我们的方法不仅消除了对量子表明的减少，而且还会产生更多以实验设置精神的结果。我们讨论我们工作的含义。具体而言，我们认为，我们的结果对超导通电代表通用绝热量子计算机的正确途径的概念提出了怀疑。
There is a tremendous interest in fabricating superconducting flux circuits that are nonstoquastic---i.e., have positive off-diagonal matrix elements---in their qubit representation, as these circuits are thought to be unsimulable by classical approaches and thus could play a key role in the demonstration of speedups in quantum annealing protocols. We show however that the efficient simulation of these systems is possible by the direct simulation of the flux circuits. Our approach not only obviates the reduction to a qubit representation but also produces results that are more in the spirit of the experimental setup. We discuss the implications of our work. Specifically we argue that our results cast doubt on the conception that superconducting flux circuits represent the correct avenue for universal adiabatic quantum computers.
