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…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
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…
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…
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…
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…
Subsystem Symmetry Fractionalization and Foliated Field Theory
Po-Shen Hsin, David T. Stephen, Arpit Dua +1
Topological quantum matter exhibits a range of exotic phenomena when enriched by subdimensional symmetries. This includes new features beyond those that appear in the conventional…
