论文摘要
量子信息容易受到环境噪声和实验缺陷的影响，从而阻碍了实用量子信息处理器的可靠性。因此，可以保护量子信息免受噪声的量子误差校正（QEC）对于通用和可扩展的量子计算至关重要。在许多不同的实验平台中，超导微波模式中的超导量子电路和玻色子编码吸引了它们在QEC中前所未有的潜力。在过去的几年中，证明了骨气QEC可以达到断裂点，即，逻辑量子量的寿命得到了增强，以超过组成实验系统的任何单个组件的寿命。除此之外，还实现了通用的门集和易于故障的操作，并实现了量子信息处理，将量子信息处理推向QEC时代。在本文中，我们回顾了玻璃纤维代码的最新进展，包括Gottesman-Kitaev-preskill代码，CAT代码和二项式代码，并讨论了在各种量子应用中的玻色粒代码的机会，从容忍性耐受量的量子计算到量子学。我们还总结了与骨骼代码相关的挑战，并从长远来看为潜在的研究方向提供了前景。
Quantum information is vulnerable to environmental noise and experimental imperfections, hindering the reliability of practical quantum information processors. Therefore, quantum error correction (QEC) that can protect quantum information against noise is vital for universal and scalable quantum computation. Among many different experimental platforms, superconducting quantum circuits and bosonic encodings in superconducting microwave modes are appealing for their unprecedented potential in QEC. During the last few years, bosonic QEC is demonstrated to reach the break-even point, i.e. the lifetime of a logical qubit is enhanced to exceed that of any individual components composing the experimental system. Beyond that, universal gate sets and fault-tolerant operations on the bosonic codes are also realized, pushing quantum information processing towards the QEC era. In this article, we review the recent progress of the bosonic codes, including the Gottesman-Kitaev-Preskill codes, cat codes, and binomial codes, and discuss the opportunities of bosonic codes in various quantum applications, ranging from fault-tolerant quantum computation to quantum metrology. We also summarize the challenges associated with the bosonic codes and provide an outlook for the potential research directions in the long terms.
