Query: Two-Party Quantum Protocols Do Not Compose Securely Against
  Honest-But-Curious Adversaries   In this paper, we build upon the model of two-party quantum computation
introduced by Salvail et al. [SSS09] and show that in this model, only trivial
correct two-party quantum protocols are weakly self-composable. We do so by
defining a protocol \Pi, calling any non-trivial sub-protocol \pi N times and
showing that there is a quantum honest-but-curious strategy that cannot be
modeled by acting locally in every single copy of \pi. In order to achieve
this, we assign a real value called "payoff" to any strategy for \Pi and show
that that there is a gap between the highest payoff achievable by coherent and
local strategies.
