Profusion of Symmetry-Protected Qubits from Stable Ergodicity Breaking
Thomas Iadecola, Rahul Nandkishore
We show how combining a discrete symmetry with topological Hilbert space fragmentation can give rise to exponentially many topologically stable qubits protected by a single discret…
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…
Measuring intrinsic relaxation rates in superconductors using nonlinear response
Wei-En Tseng, Rahul Nandkishore
We discuss intrinsic relaxation rates in superconductors, and how they may be measured using non-linear optical (terahertz) response. We consider both and -wave superconduct…
Strong Hilbert space fragmentation and fractons from subsystem and higher-form symmetries
Charles Stahl, Oliver Hart, Alexey Khudorozhkov +1
We introduce a new route to Hilbert space fragmentation in high dimensions leveraging the group-word formalism. We show that taking strongly fragmented models in one dimension and…
