# Quantum Hoare Type Theory: Extended Abstract

@inproceedings{Singhal2021QuantumHT, title={Quantum Hoare Type Theory: Extended Abstract}, author={Kartik Singhal and John D. Reppy}, booktitle={QPL}, year={2021} }

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 from being introduced. There is a need for similar techniques in the quantum regime. Inspired by Hoare Type Theory [NMB08] in the classical paradigm, we propose Quantum Hoare Types by extending the Quantum IO Monad [AG09] by indexing it with preand…
