Photon liquefaction in time
Eduardo Zubizarreta Casalengua, Elena del Valle, Fabrice P. Laussy
We provide a mechanism to imprint local temporal correlations in photon streams which have the same character as spatial correlations in liquids. Usual single-photon emitters corre…
Phases of Matrix Product States with Symmetric Quantum Circuits and Symmetric Measurements with Feedforward
David Gunn, Georgios Styliaris, Tristan Kraft +1
Two matrix product states (MPS) are in the same phase in the presence of symmetries if they can be transformed into one another via symmetric short-depth circuits. We consider how…
