Using Quantum Oblivious Transfer to Cheat Sensitive Quantum Bit Commitment Jakoby, Andreas Liskiewicz, Maciej Madry, Aleksander Two-Party Computations Quantum Protocols Bit Commitment Oblivious Transfer. We define $(varepsilon,delta)$-secure quantum computations between two parties that can play dishonestly to maximise advantage $delta$, however keeping small the probability $varepsilon$ that the computation fails in evaluating correct value. We present a simple quantum protocol for computing one-out-of-two oblivious transfer that is $(O(sqrt{varepsilon}),varepsilon)$-secure. Using the protocol as a black box we construct a scheme for cheat sensitive quantum bit commitment which guarantee that a mistrustful party has a nonzero probability of detecting a cheating.
