Charge fluctuation and charge-resolved entanglement in a monitored quantum circuit with symmetry

H Oshima, Y Fuji - Physical Review B, 2023 - APS
We study a (1+ 1)-dimensional quantum circuit consisting of Haar-random unitary gates and
projective measurements, both of which conserve a total U (1) charge and thus have U (1) …

Realizing discontinuous quantum phase transitions in a strongly correlated driven optical lattice
