Warwick Quantum is a new interdisciplinary research initiative bringing together the Computer Science, Mathematics, Chemistry and Physics Departments as well as the Warwick Manufacturing Group. Our vision is to provide a bridge between ideas in these areas to make an impact on quantum computing and quantum technologies at all levels, from theory and foundations to hardware and industrial applications.

Colloquia and Seminars

• The Cambridge-Warwick Quantum Computing Colloquium. Colloquia take place online and consist of talks dedicated to topics of interest in Quantum Computation and Quantum Complexity Theory. Our goal is to create an inclusive forum for discussion and rapid dissemination of ideas. Anyone interested in quantum computing is welcome to join.

• Special seminar on Wednesday 19th July at 11.30 in Millburn House from Alex Wood: "A new spin - and charge - on diamond quantum sensing"

  Abstract: The long coherence times of the NV centre in diamond and robust nature of the host crystal make it a prime candidate for quantum sensing in challenging environments: such as being mechanically rotated at up to 500,000 rpm, where classical rotation occurs on the same timescale as quantum coherence and has measurable effects. As well as the intrinsic interest such a platform offers, it also confers several surprising advantages to applications, such as DC magnetometry below the usual T₂* limit for standard diamond magnetometers. In this talk, I will discuss our experiments with rapidly rotating diamonds, and a new direction of research, where we investigate optical control of the electronic charge state of colour centres in diamond, including the silicon-vacancy centre in diamond. Time permitting, I will also discuss experiments where we probe the coherence of substitutional nitrogen atoms, P1 centres, which while often being a source of decoherence can be harnessed as an electron-nuclear quantum memory.
