- 58TEFull-Rank Noise Forbids Long-Range Entanglement Swapping
Proves full-rank noise caps entanglement-swapping depth; superconducting-processor experiment shows rank-deficient links sustain concurrence where full-rank ones cannot.
Thursday 10 September 2026 · 10 papers · Experimental realization of quantum-computing-enhanced sensing
- 84EExperimental realization of quantum-computing-enhanced sensing
Runs Grover search inside a microwave cavity of 128+ photons, with a transmon sensor turning an unknown signal into the oracle.
- 72TNon-Hermitian topology in driven-dissipative systems: correspondence with quantum correlations and a resource for entanglement
Shows non-Hermitian topological amplifiers produce exponentially growing correlations between modes while entanglement stays local.
- 62TRecovering Readout-Limited Fisher Information in Superconducting-Qubit Magnetometry with Squeezed Microwaves
Computes how squeezed-microwave dispersive readout recovers Fisher information lost in qubit state assignment, 27 percent sensitivity gain.
- 55TRobustness of Dynamical Casimir Effect-Induced Quantum Synchronization
Tests whether dynamical-Casimir-induced synchronization of two qubits survives realistic cQED loss, dephasing dominates.
- 55TEStrong-Drive Limits in Josephson Circuits: From Chaos to an Unbound-Resonance Threshold
Maps chaos and unbound-resonance thresholds for strongly driven Josephson circuits and confirms the flux-bias dependence in a SQUID.
- 45TKerr Induced Control of Synchronization and Quantum State Recovery in a Driven van der Pol Oscillator
Kerr nonlinearity shifts the synchronization boundary of a squeezed van der Pol oscillator, decoupled from photon statistics.
- 42TGradient-based optimal control of the non-Hermitian skin effect in optomechanical arrays
Optimizes a two-chain non-reciprocal optomechanical ladder to separate amplification from noise, mapped to cQED parameters.
- 40TResidual detuning in the laboratory-frame anti-Jaynes--Cummings model with a squeezed vacuum
Argues a laboratory-frame residual detuning in the anti-Jaynes-Cummings model cannot be cancelled by Kerr for squeezed vacuum.
- 35TPulse-Controlled Topologically Protected Quantum Batteries
Proposes topologically protected long-distance energy transfer along a pulse-modulated superconducting qubit chain.
- 30TTunable topological enhancement of covariant quantum Fisher information via non-Bloch skin effect in non-Hermitian SSH lattices
Extends covariant quantum Fisher information to non-Hermitian SSH lattices, skin effect gives 30x enhancement.
