Breakthrough promises secure quantum computing at home

Several leading providers of cloud-based services, like Google, Amazon, and IBM, already separately offer some elements of quantum computing. ">Video of How blind quantum computing could unlock secure cloud-based quantum computingIn the new study, the researchers use an approach dubbed “blind quantum computing”, which connects two totally separate quantum computing entities – potentially an individual at home or in an office accessing a cloud server – in a completely secure way. Researchers exploring quantum computing and technologies at Oxford University Physics have access to the state-of-the-art Beecroft laboratory facility, specially constructed to create stable and secure conditions including eliminating vibration. Funding for the research came from the UK Quantum Computing and Simulation (QCS) Hub, with scientists from the UK National Quantum Computing Centre, the Paris-Sorbonne University, the University of Edinburgh, and the University of Maryland, collaborating on the work. The study ‘Verifiable blind quantum computing with trapped ions and single photons’ has been published in Physical Review Letters.
