The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies thanks to a breakthrough by scientists at Oxford’s Department of Physics guaranteeing security and privacy. The advance promises to unlock the transformative potential of cloud-based quantum computing and is detailed in a new study published in Physical Review Letters.

In the new study, the researchers use an approach known as ‘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. Importantly, their new methods could be scaled up to large quantum computations.

    From the article:

    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

    This is a breakthrough because this level of security is impossible currently (as you allude to in your comment).

    Availability will still be an issue, of course.
