Conditioning on rare boundary measurement outcomes in a quantum East circuit generates states with finite two-point correlations at arbitrary distances and an underlying Sierpiński-triangle fractal structure.
Exact non-Markovian dynamics and emitted photon wave-packet profiles are derived for a single-photon emitter in a 1D waveguide with a mirror interface.
A stochastic unravelling that stays inside the permutation-symmetric subspace cuts simulation cost for N two-level emitters from O(N^5) to O(N^2) (or O(N) with extra symmetries) and extends to d-level emitters.
A minimally invasive pair of weak measurements on an atomic BEC yields the two-time density-density correlation function (Van Hove function) and its Fourier transform, the dynamical structure factor.
A symbolic quantum-trajectory construction produces closed-form exponential sums for populations and observables in multichannel Dicke superradiance, including first-order phase transition resemblance for two channels and scaling laws for balanced multi-channel cases.
Theoretical framework shows magnons emitted from spin defect ensembles into a magnetic bath retain quantum correlations from the emitters, enabling generation of single- and many-body quantum magnonic states.
A tunable chain of Rydberg atoms in tweezers mediates both coherent and dissipative entanglement between two distant micro-electromechanical oscillators.
In Markovian open quantum systems with bistability, noise-induced stochastic switching limits relaxation and follows an Arrhenius law with inverse system size as effective temperature, distinct from deterministic slow relaxation due to a small Liouvillian gap.
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.
