There has been a recent surge of interest in separation logics for quantum computation. Unlike Reynolds' initial attempts to formulate a separation logic for reasoning about _pointer manipulation_ using small, intuitive programs, the attempts in the …

Q# is a standalone domain-specific programming language from Microsoft for writing and running quantum programs. Like most industrial languages, it was designed without a formal specification, which can naturally lead to ambiguity in its …

We show that Gottesman's [1998] semantics for Clifford circuits based on the Heisenberg representation can be treated as a type system that can efficiently characterize a common subset of quantum programs. Our applications include (i) certifying …

Ongoing project with the aim to establish firm mathematical foundations for the Q# programming language.

Q# is a high-level programming language from Microsoft for writing and running quantum programs. Like most industrial languages, it was designed without a formal specification, which can naturally lead to ambiguity in its interpretation. Further, …

We extend our previous work on Gottesman Types to cover circuits beyond Clifford Group and introduce the notion of linear combination types.

Toward a unified system for programming, specifying, and reasoning about quantum programs.

As quantum computers become real, it is high time we come up with effective techniques that help programmers write correct quantum programs. Inspired by Hoare Type Theory in classical computing, we propose Quantum Hoare Type Theory (QHTT) in which …

The Heisenberg representation of quantum operators provides a powerful technique for reasoning about quantum circuits, albeit those restricted to the common (non-universal) Clifford set H, S and CNOT. The Gottesman-Knill theorem showed that we can …
