The researchers used an approach dubbed 'blind quantum computing' to connect two quantum computing entities; this simulates the situation where an employee at home or in an office remotely connects to a quantum server via the cloud.

Professor David Lucas, the co-head of the Oxford University Physics research team, said in a press release: "We have shown for the first time that quantum computing in the cloud can be accessed in a scalable, practical way which will also give people complete security and privacy of data, plus the ability to verify its authenticity."

Quantum cloud computing is where quantum resources are provided to users remotely over the internet; this allows anyone to utilise quantum computing without the need for specialised hardware or expertise.

"Dr. Peter Dmota, study lead, told TechRepublic in an email:"Strong security guarantees will lower the barrier to using powerful quantum cloud computing services, once available, to speed up the development of new technologies, such as batteries and drugs, and for applications that involve highly confidential data, such as private medical information, intellectual property, and defence.

Blind quantum cloud computing requires connecting a client computer that can detect photons, or particles of light, to a quantum computing server with a fibre optic cable.

Dr. Drmota said in the press release, "Using blind quantum computing, clients can access remote quantum computers to process confidential data with secret algorithms and even verify the results are correct, without revealing any useful information. Realising this concept is a big step forward in both quantum computing and keeping our information safe online."
