In a breakthrough for quantum computing, researchers from the University of York have developed a framework for self-testing entangled states of quantum systems. This framework provides a way for researchers to verify the state of a quantum system without needing to measure the system itself. This is an invaluable tool for developing secure quantum networks and providing assurance of the security of quantum computers. The results of the study have been published in the journal Physical Review Letters.
