Abstract

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.
