New Blueprint for Large-Scale Quantum Computing

Posted on
NQIT-supported researchers at the University of Sussex have just published their latest work: a practical blueprint for how to build a quantum computer.

This new blueprint is the work of an international team of scientists from the University of Sussex (UK), Google (USA), Aarhus University (Denmark), RIKEN (Japan) and Siegen University (Germany).

Prof. Hensinger heads the Ion Quantum Technology Group at the University of Sussex and is Director of the Sussex Centre for Quantum Technologies. The group is part of the UK Quantum Technology Hub on Networked Quantum Information Technologies which is funded by the Engineering and Physical Sciences Research Council (EPSRC).

This video illustrates the working principle of a modular scalable trapped ion quantum computer using microwaves and ion shuttling techniques. The novel architecture makes use of the new invention made by the Ion Quantum Technology Group at the University of Sussex that drastically simplifies the engineering challenges linked to the development of such technology.
