Quantum annealing processors implement analog-digital quantum computing via effective XY-model evolution combined with auxiliary-qubit arbitrary-basis initialization and measurement, demonstrated through oscillations, fermionic quantum walks, and Anderson localization.
A nonsecular Floquet generalized master equation framework is developed for open ultrastrong cavity-QED, demonstrating that dissipation is governed by quasienergies rather than static dressed resonances.
Subsystem decoherence on extended cluster states generates a hierarchy of mixed SPT phases ending in Z2 SWSSB with glassy GHZ entanglement.
Proves TMSV optimality for finite-energy incoherent stochastic sensing and shows entanglement is required for independent gain estimation, with non-Gaussian to Gaussian transition in unentangled states as dead time grows.
Bosonic quantum statistics enhance collective phases in a 1D quantum active Ising model on a lattice.
Operators evolving under the adjoint Liouvillian in open quantum systems can exhibit a genuine Mpemba effect, with general conditions derived and validated across three setups.
Decoherence of the color code produces a mixed state with topological entanglement negativity ln 2 that corresponds to an emergent single toric code.
General probe-environment correlations enable non-completely positive encodings that surpass the thermal-state bound in quantum thermometry precision.
Temporal fluctuations of the aSTC distinguish integrable and chaotic regimes in both closed and open long-range XYZ spin chains, retaining diagnostic power under non-Markovian noise where OTOC fails.
A multilevel tensor-network technique compresses Lindblad dynamics of interacting bosonic modes by combining global purification, entanglement compression, and quantics Fock representation, demonstrated on cat qubits and transmon ionization.
Continuous driving in chiral quantum networks allows transient concurrence to exceed the undriven 2/e benchmark because nonsecular terms mix dressed-state coherences under strong driving.
Noise correlations increase the fidelity of randomly compiled Clifford circuits under a broad class of Gaussian noise.
Transient precision enhancement in Markovian quantum thermometry requires an initially cold probe and this requirement survives some memory effects but is eliminated by strong non-Markovian collisional dynamics.
Spin-induced noncommutativity in the Bateman oscillator yields discrete scaling covariance in amplified and damped modes, producing self-similar evolution and history-dependent non-Markovian reduced dynamics.
A Redfield master equation model of a thermoelectric information engine reveals that coherent tunneling enhances the autonomous Maxwell demon mechanism before phonon-induced decoherence suppresses both transport and information flow.
io-HEOM accurately captures non-Markovian waveguide QED arising from spatially non-local coupling and non-linear dispersion in different spectral densities.
A second-order perturbative framework decomposes coherence terms in the quantum first law into coherent heat and work, linking them to Fermi's golden rule transition rates.
Spin-induced deformation creates a Bateman dual oscillator whose reduced non-Markovian dynamics produces time-crystal-like ordering and fractal scaling in a closed quantum system.
Energy modeling and parameter optimization for cat-qubit superconducting quantum computers performing semiclassical QFT with error correction indicates an energetic advantage over classical systems for more than 26 qubits under cryogenic assumptions.
A driven-dissipative model for qudit-resonator systems is used to derive expressions for quantum/tunneling capacitances and Sisyphus/Hermes resistances that change when the two subsystems influence each other dynamically.
The paper demonstrates a quantum Mpemba-like effect during Unruh thermalization of a UDW detector and identifies maximum fidelity difference as a diagnostic distinguishing quantum Unruh thermalization from classical thermal bath effects.
Higher-dimensional two-way QKD protocols using mutually unbiased bases and Heisenberg-Weyl operators yield secret keys for stronger individual attacks and improved robustness to collective eavesdropping via entropic uncertainty relations.
Derives a generalized GKSL master equation for PT-symmetric two-level open quantum systems and compares non-Markovian witness, fidelity, and entanglement with Hermitian counterparts.
