Nonlocal non-Gaussian operations engineer entangled probe states that outperform two-mode squeezed states and local non-Gaussian protocols in signal-to-noise ratio for quantum illumination under photon loss.
Nonlocal magic in fermionic Gaussian states is bounded by the entanglement spectrum of the covariance matrix, is extensive in the Haar ensemble, peaks at criticality in the Kitaev chain, and grows diffusively under random circuits.
A VMBQC model restricted to one extra trainable parameter generates distributions that the corresponding unitary model cannot learn.
VaFES constructs a latent space from reversible collective variables and variationally optimizes a tractable-density generative model to produce a continuous free energy surface from which rare events are directly sampled.
Introduces absolute Schmidt number for states invariant under global unitaries, with witness and moment-based detection methods plus resource measures, extended to covariant channels.
A pre-training diagnostic map based on spectral correlation resemblance to IQP circuits and excess structural complexity identifies suitable datasets like turbulence data for quantum generative models, yielding competitive low-resource performance.
A hybrid classical-quantum scheme compresses and disentangles bottleneck layers of pre-trained neural networks into MPO form for execution on quantum devices, validated via proof-of-concept on MNIST and CIFAR-10 image classification.
The authors introduce MuTA as a universal quantum neural network for MBQC and numerically demonstrate its ability to learn gates, classify quantum states, and process data under noise, including photonic hardware constraints.
Non-stabilizerness of the Hubbard dimer is computed with robustness of magic and stabilizer Rényi entropy, revealing it as a resource distinct from fermionic non-Gaussianity and superselected entanglement.
Averaged accessible information under Haar-random local measurements is a function of local purity and distinguishes dynamical confinement, ballistic transport, scar revivals, and many-body localization in quantum many-body systems.
Ergotropy in the battery corresponds one-to-one with total nonstabilizerness under U(1)-symmetric charger-battery interactions, while maximum average charging power in Clifford evolution is achievable even with zero initial magic.
A no-cloning-style bound proves that observable exterior quantum hair on semiclassical black holes is incompatible with exact horizon smoothness unless the infalling state is pre-entangled.
A hybrid policy with classical preprocessing and a parameterized quantum circuit learns effective multiqubit disentanglement scheduling from partial two-qubit reduced-state observations, with preprocessing dominating performance and wider circuits outperforming deeper ones.
Dressed states generated by static fields protect Heisenberg scaling in quantum metrology for low-temperature noise precisely when the signal generator lies outside the linear span of the system-environment coupling operators.
A mean-field phase-space method emulates continuous-time dynamics of up to thousands of qubits with quadratic cost, capturing single-qubit observables qualitatively on transverse-field Ising models.
Derives closed-form effective inverse temperatures for qubit thermalization via quantum SWITCH with identical/asymmetric baths and identifies optimal control parameters for enhanced heating/cooling.
A QMC-based framework tests the lattice-Bisognano-Wichmann ansatz for reconstructing entanglement Hamiltonians in 2D systems without Lorentz invariance or translational symmetry, finding good accuracy for ordinary boundaries.
Introduces non-Gaussian control parameters (s0, δ0) and an optimization method that reduces photon detections by a factor of three and increases preparation probability by nearly 10^8 for GKP states, with gains shown across cat, cubic phase, and random states.
Interference between local measurement histories on two qubits generates entanglement, persisting even after averaging over detector readouts.
In the random-field XXZ model, Wehrl-Rényi entropy growth for z-polarized product states shows non-monotonic dependence on initial entanglement, with the first regime set by local integrals of motion and the second by inter-site correlations.
Disorder does not alter the presence or absence of measurement-induced phase transitions in noninteracting fermions; the long-time behavior is controlled by the same nonlinear sigma model with renormalized parameters.
Experimental detection of entanglement in multimode Gaussian states via high-order intensity correlation moments from parametric down-conversion sources.
Physics-informed quantum neural networks trained on noisy measurements can construct nontrivial decision boundaries to classify quantum states via order parameters and are suited for NISQ hardware due to links with Markovian open many-body systems.
