Blind quantum computation is a new secure quantum computing protocol which
enables Alice who does not have sufficient quantum technology to delegate her
quantum computation to Bob who has a fully-fledged quantum computer in such a
way that Bob cannot learn anything about Alice's input, output, and algorithm.
In previous protocols, Alice needs to have a device which generates quantum
states, such as single-photon states. Here we propose another type of blind
computing protocol where Alice does only measurements, such as the polarization
measurements with a threshold detector. In several experimental setups, such as
optical systems, the measurement of a state is much easier than the generation
of a single-qubit state. Therefore our protocols ease Alice's burden.
Furthermore, the security of our protocol is based on the no-signaling
principle, which is more fundamental than quantum physics. Finally, our
protocols are device independent in the sense that Alice does not need to trust
her measurement device in order to guarantee the security.
