Imperative Quantum Programming with Ownership and Borrowing in Guppy

Linear types enforce no-cloning and no-deleting theorems in functional quantum programming. However, in imperative quantum programming, they have not gained widespread adoption. This work aims to develop a quantum type system that combines ergonomic …

Guppy: Pythonic Quantum-Classical Programming

Talk on Guppy at the Quantum Software 2.0 workshop co-located with IEEE Quantum Week 2024.

Guppy: Pythonic Quantum-Classical Programming

We present ongoing work on Guppy, a domain-specific language embedded in Python that allows users to write high-level hybrid quantum programs with complex control flow in Pythonic syntax, aiming to run them on actual quantum hardware.

Q# as a Quantum Algorithmic Language

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 …

The Essence of Q#

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

Toward a Type-Theoretic Interpretation of Q#

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, …

Toward Formalizing 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. We aim to …

Quantum Hoare Type Theory

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

Quantum Hoare Type Theory

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 …

Quantum Hoare Type Theory: Extended Abstract

As quantum computers become real, it is high time we come up with effective techniques that help programmers write correct quantum programs. In classical computing, formal verification and sound static type systems prevent several classes of bugs …
