'Blind' Quantum Computing Proposed For the Cloud 89
judgecorp writes "Researchers at Vienna's Quantum Science and Technology Center have proposed that 'blind' quantum computing could be carried out securely in the cloud. When (if?) quantum computers are developed, they will be very fast, but not everyone will have them. Blind quantum computing will be useful, because it shows that users can encode 'qubits' and send them to a shared quantum computer to be worked on — without the quantum computer having any knowledge of what the data is (abstract). The data also cannot be decoded form the qubit while it is in transit. It's good to know that quantum computers will be secure when they exist. At the moment, of course, they are even more secure, by virtue of their non-existence."

As a physicist working in the field, let me correct two things:
Quantum computing is not a branch of computer science; it is not logic and mathematics. It is a branch of physics. It is also why you find it hard to believe that both the input and output is unknown to the quantum computer.
@OP: They do exists, just not in stores yet, a natural result of having unsatisfactory shape.. Try paying a visit to a QC laboratory.
