Real-time renormalization group on quantum operations produces chaotic flows in coherent-dominant regimes, and the measurement-induced PT transition belongs to the 1D Yang-Lee edge singularity universality class.
Bit flips in dissipative cat qubits are accompanied by time-localized photon bursts that enable their detection as erasures via photon counting or homodyne monitoring.
Saturation of bit-flip suppression in cat qubits originates from chaotic dynamics in memory-buffer interactions when adiabatic approximation breaks and cross-Kerr plus dephasing are present.
Weak anharmonicity induces dissipation into dark states of photon-emitter pairs; first- and second-order perturbative corrections to the wavefunction are derived and applied to the master equation.
Non-Hermitian Gamma interaction on the TFIM induces a PT-broken gapless phase with long- and short-range spin-nematic correlations, diagnosable via dynamical nematic correlators.
Numerical study of monitored fermions finds integrable cases fit by linear-to-power-law interpolation for entanglement scaling, SYK shows volume law, and t-V hints at transition, with unrelated anomalous delocalization in Hilbert space.
