Many-body contextuality and self-testing quantum matter via nonlocal games
Oliver Hart, David T. Stephen, Evan Wickenden +1
Contextuality is arguably the fundamental property that makes quantum mechanics different from classical physics. It is responsible for quantum computational speedups in both magic…

Preparing matrix product states via fusion: constraints and extensions
David T. Stephen, Oliver Hart
In the era of noisy, intermediate-scale quantum (NISQ) devices, the efficient preparation of many-body resource states is a task of paramount importance. In this paper we focus on…

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…
