Error Resilience and Unitary 2-Designs
Zheng-Hang Sun, Fabian Ballar Trigueros, Xhek Turkeshi +1
Encoding-error-decoding circuits provide a setting for studying protection of quantum information against errors. In these circuits, an encoding unitary is followed by an error lay…
Unitary Designs from Doped Matchgate Circuits
Fabian Ballar Trigueros, Zheng-Hang Sun, Xhek Turkeshi +2
Matchgate circuits realize free-fermion dynamics: they are efficiently classically simulable, yet cannot on their own generate the generic randomness required for universal computa…
Quantum Circuits as a Dynamical Resource to Learn Nonequilibrium Long-Range Order
Fabian Ballar Trigueros, Markus Heyl
Equilibrium statistical ensembles impose stringent constraints on phases of quantum matter. For example, the Mermin-Wagner theorem prohibits long-range order in low-dimensional sys…
