Fourth-order ordering-sensitive Bargmann invariants supply the first universal pairwise criterion for set coherence, and applying it to all pairs yields a complete test for any finite family of states.
In U(1)-symmetric random circuits, initial states with lower stabilizer Rényi entropy generate nonstabilizerness faster than those with higher entropy, with the effect also depending on spatial charge structure and extending to SU(2) circuits and Hamiltonian dynamics.
Dynamic Bayesian network reconstruction yields backaction-free fluctuation diagnostics for an engineered population-inverted qubit Otto engine, revealing enhanced work and power with reduced relative noise in full thermalization and structured operating sectors for finite-time cycles.
Complex measurements in three-qubit entanglement protocols concentrate more bipartite entanglement and cut required bond occupation probability by 22.7% in honeycomb-lattice quantum network percolation.
A three-site open quantum bosonic chain with local parametric driving, nonlinear damping, and nonlocal dissipative couplings exhibits Turing-type pattern formation and mode competition, bridging classical reaction-diffusion dynamics with quantum master-equation dynamics.
Continuous temporal processing in open quantum reservoirs is shown to obey a generalized Landauer bound, with predictive performance tied to resonant energy-gap matching and to quantum coherence.
A quantum Zeno dynamics protocol confines the evolution of a finite-time Otto-cycle quantum heat engine to a subspace that preserves instantaneous energy populations, recovering quasistatic efficiency with added thermodynamic costs from monitoring and switching.
Two quantum states ρ₁ and ρ₂ commute exactly when tr(ρ₁²ρ₂²) = tr(ρ₁ ρ₂ ρ₁ ρ₂).
An intrinsic reference basis yields a cohesion index that contracts exponentially under aligned dephasing, giving operational classicality and candidate pointer sectors.
Conservation laws in quantum circuits and Hamiltonians replace logarithmic coherence saturation with slow hydrodynamic relaxation globally and produce algebraic peak-time growth locally, unlike ergodic cases.
Magnetoresistance originates from decoherence throughout the Fermi sea, with conductivity parameterized by two complex decoherence times that scales linearly with impurity density, unlike the inverse scaling in the Drude model.
A nonlinear criterion detects coherence transfer in quantum networks with only two measurements of network-state populations, remaining valid even with uncharacterized checkpoint nodes, and is experimentally shown in four- and six-photon entanglement networks.
Krylov shadow tomography produces exponentially converging bounds on quantum Fisher information that exactly match the QFI for low-rank states and outperform existing polynomial lower bounds.
A new optimization-based protocol estimates quantum coherence from scarce data with system-size-independent cost and is experimentally demonstrated.
Coherence enables anomalous work extraction in qubit gate dynamics via negative Kirkwood-Dirac quasiprobabilities, with a compositional relation connecting circuit-level work statistics to individual gates.
The authors propose a catalytic coherence-amplification protocol claimed to recover known quantum states from noisy copies without an error threshold, using 8-32 copies in numerical benchmarks.
A quantum speed limit for observables is formulated from the trace-norm asymmetry of the time-dependent state, observable through weak measurements and bounding the quantum Fisher information for the conjugate parameter.
Defines isoergotropic states and ergotropy-preserving operations that redistribute coherent-incoherent or displacement-squeezing components in quantum batteries without changing total ergotropy.
