Blind Quantum Computing

“Great, we have finally built a quantum computer, now I only have to go to the Netherlands and stick my USB drive in there!”  -  Molecular scientist based in Japan

Building a quantum computer is not an easy task nor a cheap one. That is why it is expected that at the start of this new era of computation, only a few of such computers are going to be up and running. This will require many people from around the globe to reserve time-slots to operate them remotely. 

Unlike a classical cloud-based computation network, a quantum system will allow us to communicate in such a way that not even the quantum computer will know what information is processed. This is precisely why it is called blind computing and would allow our scientist to run his experiments without risking his valuable research.

Further thinking

Obviously, at our end, we would need quite an excellent classical computer to transfer our ideas into single qubits to be sent to the remote node. Luckily we are already quite good at this. The most crucial part is that the small and easy to access nodes just need as much as one qubit of quantum computational power. Could you tell why only one qubit would be enough?
