Breakthrough promises secure and private quantum computing at home (www.physics.ox.ac.uk)

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.

Maybe not once quantum computers become more common.

Our current encryption methods can be represented as wave functions. This allows a sufficiently large quantum computer to solve for the keys in very little time.

There are new algorithms being developed that should defend against this. So you may still be correct.
