  We introduce a simple protocol for verifiable measurement-only blind quantum
computing. Alice, a client, can perform only single-qubit measurements, whereas
Bob, a server, can generate and store entangled many-qubit states. Bob
generates copies of a graph state, which is a universal resource state for
measurement-based quantum computing, and sends Alice each qubit of them one by
one. Alice adaptively measures each qubit according to her program. If Bob is
honest, he generates the correct graph state, and therefore Alice can obtain
the correct computation result. Regarding the security, whatever Bob does, Bob
cannot learn any information about Alice's computation because of the
no-signaling principle. Furthermore, evil Bob does not necessarily send the
copies of the correct graph state, but Alice can check the correctness of Bob's
state by directly verifying stabilizers of some copies.
