Certifying the building blocks of quantum computers

Bell’s theorem has been proposed to certify quantum sources and measurements in a way that is independent of the imperfections of the actual implementation. The team of Prof. Sangouard showed how Bell’s theorem can be used to certify coherent operations for the storage, processing, and transfer of quantum information. This completes the set of tools needed to certify all building blocks of a quantum computer. These results have been published in Physical Review Letters and highlight by the SNF.
