The articles in this special section focus on quantum computing. Quantum computers show great potential for enabling efficient solutions to a variety of important problems, where classical computers suffer from excessive time and/or space complexity. This rich set of problems spanning cryptography and optimization, to name a few, goes far beyond efficient simulation of quantum mechanics, which gave rise to this exciting computing discipline originally. Rigorous efforts from industry and academia to pave the way for practical quantum computers at scale have recently rendered proof-of-concept demonstrations featuring tens of qbits. However, significantly larger quantum systems are required to unlock the quantum advantage over classical computers.

量子计算特刊


本专题中的文章重点关注量子计算。量子计算机在有效解决各种重要问题方面表现出巨大的潜力，而经典计算机则面临着时间和/或空间复杂性过高的问题。仅举几例，涵盖密码学和优化等领域的丰富问题远远超出了量子力学的有效模拟，而量子力学最初催生了这一令人兴奋的计算学科。工业界和学术界为大规模实用量子计算机铺平了道路，最近做出了具有数十个量子位的概念验证演示。然而，需要更大的量子系统才能发挥相对于经典计算机的量子优势。
