Braiding for the win: Harnessing braiding statistics in topological states to win quantum games
Oliver Hart, David T. Stephen, Dominic J. Williamson +1
Nonlocal quantum games provide proof of principle that quantum resources can confer advantage at certain tasks. They also provide a compelling way to explore the computational util…
Towards absolutely stable ergodicity breaking in two and three dimensions
Charles Stahl, Oliver Hart, Rahul Nandkishore
We propose new physically reasonable systems capable of avoiding ergodicity at infinite time in the thermodynamic limit, even with generic perturbations and when coupled to a heat…
Exact analytic toolbox for quantum dynamics with tunable noise strength
Mert Okyay, Oliver Hart, Rahul Nandkishore +1
We introduce a framework that allows for the exact analytic treatment of quantum dynamics subject to coherent noise. The noise is modeled via unitary evolution under a Hamiltonian…
Many-body quantum catalysts for transforming between phases of matter
David T. Stephen, Rahul Nandkishore, Jian-Hao Zhang
A catalyst is a substance that enables otherwise impossible transformations between states of a system, without being consumed in the process. In this work, we apply the notion of…
Robust Hilbert space fragmentation in group-valued loop models
Alexey Khudorozhkov, Charles Stahl, Oliver Hart +1
We introduce a large class of models exhibiting robust ergodicity breaking in quantum dynamics. Our work is inspired by recent discussions of "topologically robust Hilbert space fr…
Playing nonlocal games across a topological phase transition on a quantum computer
Oliver Hart, David T. Stephen, Dominic J. Williamson +2
Many-body quantum games provide a natural perspective on phases of matter in quantum hardware, crisply relating the quantum correlations inherent in phases of matter to the securin…
