Self-guaranteed measurement-based quantum computation

Understand

In order to guarantee the output of a quantum computation, we usually assume that the component devices are trusted.

• However, when the total computation process is large, it is not easy to guarantee the whole system when we have scaling effects, unexpected noise, or unaccounted correlations between several subsystems.
• If we do not trust the measurement basis nor the prepared entangled state, we do need to be worried about such uncertainties.
• To this end, we proposes a "self-guaranteed" protocol for verification of quantum computation under the scheme of measurement-based quantum computation where no prior-trusted devices (measurement basis nor entangled state) are needed.
