A Propositional Proof System for Log Space
The proof system G∗ 0 of the quantified propositional calculus corresponds to NC1 , and G∗ 1 corresponds to P, but no formula-based proof system that corresponds log space rea...

Simulatable Security and Polynomially Bounded Concurrent Composability
Simulatable security is a security notion for multi-party protocols that implies strong composability features. The main definitional flavours of simulatable security are standa...

A Formalization of Polytime Functions
Abstract. We present a deep embedding of Bellantoni and Cook’s syntactic characterization of polytime functions. We prove formally that it is correct and complete with respect to...

Quantum Computing, Postselection, and Probabilistic Polynomial-Time
I study the class of problems efficiently solvable by a quantum computer, given the ability to "postselect" on the outcomes of measurements. I prove that this class coin...
