Abstract

This theme issue concerns exciting new developments at the interface of quantum and particle physics, together with quantum technologies and their application to fundamental particle physics. This is a new priority area for European and US research as identified by the United States DoE and European funding authorities as well as by CERN. The theme issue brings together key people involved in this effort with a positive outlook to the future. The volume explores fresh synergies between quantum and particle science and the potential for exciting new cross disciplinary collaboration. Particle physics today is characterized by the success of the Standard Model [1], including the recent discovery of the Higgs boson at the Large Hadron Collider, LHC, at CERN. So far there is no evidence for extra particles or interactions in the energy range of present experiments. However, some new physics is required to explain the tiny neutrino masses, baryogenesis with extra CP violation, and the phenomena of dark matter and dark energy. The energy scale of this new physics is presently unknown, with the quest for this new physics a prime topic for both experimentalists and theoreticians. Theoretically, non-abelian gauge theories require nonperturbative treatment because of strong coupling and confinement dynamics in the infrared. Inspired by Feynman’s initial intuition of quantum computing [2], task-specific quantum simulators are being used in a first step to simulate a quantum system using…
