We propose a new concept, oblivious quantum computation, which requires
performing oblivious transfer with respect to the computation outcome of the
quantum computation, where the secrecy of the input qubits and the program to
identify the quantum gates are required. We propose a two-server protocol for
this task, which realizes an exponential improvement for the communication
complexity over the simple application of two-server (quantum) oblivious
transfer to the sending of the computation result. Also, we discuss delegated
multiparty quantum computation, in which, several users ask multiparty quantum
computation to server(s) only using classical communications. We propose a
two-server protocol for the latter task as well.
