Fault-tolerant verifiable blind quantum computing with logical state remote preparation

Understand

Verifiable blind quantum computing allows a client with poor quantum devices to delegate universal quantum computing to a remote quantum server in such a way that the client's privacy is protected and the honesty of the server is verified.

• In existing protocols, the client has to send single-qubit states to the server.
• These states might be decohered by the channel noise.
• Furthermore, the client hides some "trap" qubits in the server's register so that the client can detect the server's deviation.
