CHEQS

The implementation of highly entangled quantum states is at the basis of most quantum technologies in the area of quantum computing, quantum simulation, quantum sensing or quantum communication. NISQ (noisy-intermediate-scale-quantum) devices, i.e. systems with a few dozen to hundreds of physical qubits, are now becoming a reality. In this context, the objective of the EOS project CHEQS (2022-2026) is to combine the expertise of the leading experimental and theoretical Belgian groups working in the field of quantum science and technology to tackle the problem of properly engineering highly entangled quantum states. The projects aims in particular at theoretically exploring which quantum states can be prepared and integrated in various quantum devices, investigating how such states can be theoretically characterized and certified, and experimentally implementing those protocols. In this project, Hasselt University is in charge of generating entangled states in arrays of nitrogen-vacancy (NV) centers qubits in diamond, usable for metrology applications.
