| Research Abstract |
Quantum blind computation can be discussed in the measurement-based quantum computation model. As a special case, ancilla-driven quantum computation is defined as computation where measurements are made only on the measurement system and computation is carried on the computational system and those two system are separated. In the ancilla-driven computation model, we derive sufficient conditions for the blindness and show a bind protocol. In cryptography, the universal composability guarantees that a prococol can be used as a part of larger cryptosystems. We show that Fujii-Morimae blind computation, where only the client makes measurements, is universally composable.
