Under local amplitude damping, GHZ-type states lose magic, regain it after entanglement death, and the rebirth threshold exactly mirrors the entanglement-death threshold: γ₊ = 1 − γₑ for every n.
Record deep-strong coupling (normalized ratio >1.6) realized in 3D Kane fermion Landau polaritons, with gauge-invariant theory showing emergent A² term that precludes superradiant quantum phase transition.
Relativistic Maxwell-Bloch equations are derived showing that radiating system response and coherence between emitters are preserved across reference frames, with timescales and intensity transforming as expected relativistically.
An SU(4) symmetric Pauli-type rate equation unifies collective dissipation across seven four-level atomic topologies, yielding superlinear peak-intensity scaling exponents of 1.81–1.92.
A full-wave Green's function framework for non-Markovian collective single-photon emission in open-system QED, including a counter-term scheme to compensate for finite-bandwidth dispersive interaction errors.
Coupling-Grouped XY-QAOA enables joint anomaly-feature selection via a constraint-preserving grouped-angle QAOA variant, achieving 45.9-61.3% circuit depth reduction and larger feasible executions (64 qubits at p=2) on IBM Heron hardware compared to standard approaches.
VF-QCTRL combines LLMs with physics-informed symbolic reasoning and optimization to produce analytic control protocols that match or exceed conventional solvers across a new 16-task benchmark spanning single/multi-qubit, closed/open, and noisy systems.
Observation of tunable superradiant frequency combs from collective spin dynamics in a driven-dissipative cavity-QED system, with a proposed connection to continuous time crystals.
In the Dicke model, multiparameter critical metrology achieves square-root divergent scaling for two parameters via higher-order QFIM contributions, while a Dicke dimer with triple point restores quadratic scaling for specific pairs.
Cavity coupling to a 1D Ising chain yields an exactly solvable finite-temperature superradiant phase transition driven by photon-mediated long-range interactions.
Subradiance from entangled Dicke states in atomic hydrogen renders galactic halo gas dark in emission and transparent, matching dark matter properties at observed temperatures near 100 K.
Derives CQED-DDI model separating free-space and dielectric effects, concluding direct intermolecular interactions are essential for multi-molecule exciton-polariton dynamics.
Reports experimental generation of remote Bell entanglement between two giant atoms with fidelity 0.89 using driven-dissipative stabilization and in-situ frequency tuning.
Simulations and experiments show that perturbing the tryptophan network in microtubules allows chemically addressable tuning of their ultraviolet quantum yield.
The Lindblad equation is valid only within a finite time window controlled by the timescales of the bath, the system, and the rotating-wave approximation, with failure at early and late times.
