To explore the possibility of finding explicit optimal or near-optimal protocols, we focus on a class which generalizes such protocols. There has been increased research activity in optimization concerning generalizing theory and algorithms for linear programming to much wider classes of optimization problems such as semidefinite programming. Quantum money from hidden subspaces.

Interaction in a quantum world – We also derive a lower bound by constructing a bit-commitment protocol from an oblivious transfer protocol. A simpler proof of existence of quantum weak coin flipping with arbitrarily small bias [ pdf ].

Known lower bounds for bit-commitment then lead to a constant lower bound on the bias of oblivious transfer.

Abstract This thesis concerns the analysis of the unconditional security of quantum cryptographic protocols using convex optimization techniques.

An approach to empirical logic. First, it allows one to model cheating probabilities using a simpler class of optimization problems known as second-order cone programs SOCPs. For example, semidefinite programming provides a tool for potentially improving results based on linear programming or investigating old problems that have eluded analysis by linear programming.
