Bosonic analog of Dicke superradiance shows strong-interaction superradiant emission and weak-interaction subradiant crossover, both capturable by analogous rate equations via permutational symmetry.
Some absolutely separable states can generate entanglement probabilistically via purity-non-generating operations, but completely absolutely separable states cannot; a new sufficient separability condition based only on largest and smallest eigenvalues and local dimension is derived.
Adjusting quantum gate timing via scheduling suppresses idling errors and improves accuracy in simulations and hardware experiments without added gates, supported by an analytical density-matrix derivation.
For product and X-form separable noise, exact Bell-mixing thresholds for entanglement and teleportation advantage are derived as 'absorption capacities' mapped by lambda = C/(1+C).
Multilevel anharmonic transmon probes extract more quantum Fisher information about temperature than qubit probes, with bounded anharmonic models confirming robustness beyond the Duffing regime.
Demonstrated gate-tunable supercurrents in Josephson junctions on Ge quantum wells with Ic >100 nA and IcRn=8.63 μV using in-situ Al contacts and deep mesa etch for low-loss integration.
Mixed Floquet lattices realize momentum-resolved Weyl topology via power transfer but the integrated real-space response follows Rice-Mele pumping rather than static Weyl semimetal behavior.
Derives KL_W and R_DV regularizers from Girsanov's theorem that reduce infidelity by up to 50% and improve robustness to noise mismatch on single- and multi-qubit benchmarks including an IBM Kingston calibration.
Canonical mapping of quantum-dot-superconductor clusters enables neural quantum-state calculations that reveal trivial singlet, Heisenberg-like, and critical regimes with 1D gaplessness and 2D triplet states.
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.
A single flux line with cryogenic filtering and compensated waveform synthesis enables high-fidelity XY/Z control and reset on fluxonium qubits while preserving >100 μs coherence.
Feedback calibration policies outperform open-loop baselines in low-latency quantum runtime regimes when workloads are quality-sensitive and start with aged calibrations.
A one-bit feedback protocol estimates a superconducting qubit's bistable frequency from a single shot and stabilizes gate performance with 77% error reduction at 136 kHz bandwidth.
A theoretical framework is proposed for direct generation of flying cat-qubit states from vacuum with simultaneous logical control and noise robustness in Kerr and two-photon-dissipation systems.
Lindblad dynamics admits a universal closed algebra of Hermitian operators with model dependence isolated in a single set of coefficients.
A pipelined framework with speculation for logical operations in fault-tolerant quantum computation reduces total pipeline steps by 20-40% on benchmarks by overlapping control, execution, and decoding stages.
A new class of superconducting tunable resonators enables fast, low-loss magnetometry at milli-kelvin temperatures with MHz sampling rates.
Benchmark comparison finds the three-mode Duffing model tracks the circuit-based transmon reference more closely than the effective two-level model for spectra and two-qubit terms, while driven dynamics show multilevel effects absent from the effective model.
QRQT protects quantum teleportation's classical channel with PQC, showing quantum memory coherence as the central bottleneck that caps secure distance at 191-199 km and produces a non-monotonic joint attack probability.
A transmon quantum battery charged by coherent ancillas achieves improved control of stored energy and extraction in experimentally accessible parameter regimes.
Proposes a fabless-foundry ecosystem for superconducting quantum chips built on certified PDKs, SPICE-Q multiphysics modeling, parameterized cells, Q-EDA automation, and a quantum-IP market.
For noisy near-term quantum devices, the paper recommends shallow angle encoding over amplitude encoding once two-qubit error rates exceed roughly 10^-3.
Introduces a JAX-based framework for pulse-level QML with composable ansatze, end-to-end pulse optimization, and Fourier-analytic diagnostics.
