Entering the era of post-quantum supremacy has given one the ability to precisely control
noisy intermediate-scale quantum (NISQ) processors with multiqubits and extract valuable …

Modified Jarzynski equality in a microcanonical ensemble

LA Williamson - arXiv preprint arXiv:2409.10810, 2024 - arxiv.org
We show that the conventional Jarzynski equality does not hold for a system prepared in a
microcanonical ensemble. We derive a modified equality that connects microcanonical work …
