Local Variables and Quantum Relational Hoare Logic (report, 2020)

[ eprint ]

We add local variables to quantum relational Hoare logic (Unruh, POPL 2019). We derive reasoning rules for supporting local variables (including an improved “adversary rule”). We extended the qrhl-tool for computer-aided verification of qRHL to support local variables and our new reasoning rules.
