Special Issue on Quantum Computing

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.
