摘要
<正>In recent years, much work has been directed to the development of technologies to enable the long-term goal of scalable, universal quantum computers. This effort is motivated by the promise of quantum computational speed-up in tasks such as integer factoring, quantum simulation, and solving systems of linear equations. Despite the tremendous advances in quantum technologies reported in the last few years, the implementation of a large-scale universal quantum computer is still far from our current capabilities. Hence,
