Entanglement Before Spacetime in Quantum-Gravity-Induced Interactions

Hollis Williams·Feb 5, 2026

Quantum-gravity-induced entanglement of massive systems (QGEM) is commonly approximated in the nonrelativistic static limit by a Newtonian interaction between spatially separated masses. In this work, we reformulate the gravitationally mediated inter...

Quantum scattering in helically twisted geometries: Coulomb-like interaction and Aharonov-Bohm effect

Augusto Tadeu P. de Araújo, Edilberto O. Silva·Feb 5, 2026

We investigate the scattering of a charged quantum particle in a helically twisted background that induces an effective Coulomb-like interaction, in the presence of an Aharonov-Bohm (AB) flux. Starting from the nonrelativistic Schrödinger equation in...

Distributed Quantum Error Mitigation: Global and Local ZNE encodings

Maria Gragera Garces·Feb 4, 2026

Errors are the primary bottleneck preventing practical quantum computing. This challenge is exacerbated in the distributed quantum computing regime, where quantum networks introduce additional communication-induced noise. While error mitigation techn...

Taming multiparty entanglement at measurement-induced phase transitions

Liuke Lyu, James Allen, Yi Hong Teoh +2 more·Feb 4, 2026

Measurement-induced phase transitions (MIPT) give rise to novel dynamical states of quantum matter realized by balancing unitary evolution and measurements. We present large-scale numerical simulations of a trapped-ion native MIPT, argued to belong t...

Ising-Induced Spectral Broadening Resolves the Relaxation Bottleneck in Superradiant Masers

Hongze Ding, Jiuqing Liang·Feb 4, 2026

The recent observation of self-induced superradiant masing [[W. Kersten et al., Nat. Phys. 22, 158 (2026)]] revealed a collective relaxation timescale significantly slower than predicted by standard coherent transport models. Here, we elucidate the m...

Restoring Landauer's Principle for Unitarily Transformed Thermal Reservoirs

Hao Xu·Feb 4, 2026

Landauer's principle, a cornerstone of quantum information and thermodynamics, appears to be violated when the thermal reservoir is replaced by a squeezed thermal state (STS). We introduce a formal extension of the principle to such unitarily transfo...

Squeezing-Enhanced Rotational Doppler Metrology

Javier Navarro, Mateo Casariego, Gabriel Molina-Terriza +2 more·Feb 4, 2026

A rotating surface can induce a frequency shift in incident light by changing its angular momentum, a phenomenon known as the rotational Doppler effect. This effect provides a means to estimate the angular velocity of the rotating surface. In this wo...

Restoring Sparsity in Potts Machines via Mean-Field Constraints

Kevin Callahan-Coray, Kyle Lee, Kyle Jiang +1 more·Feb 4, 2026

Ising machines and related probabilistic hardware have emerged as promising platforms for NP-hard optimization and sampling. However, many practical problems involve constraints that induce dense or all-to-all couplings, undermining scalability and h...

Stochastic Thermodynamics of Quantum-Induced Stochastic Dynamics

Pedro V. Paraguassú·Feb 3, 2026

Quantum-Induced Stochastic Dynamics arises from the coupling between a classical system and a quantum environment. Unlike standard thermal reservoirs, this environment acts as a dynamic bath, capable of simultaneously exchanging heat and performing w...

Mind the Gap: Anti-Critical Quantum Metrology

George Mihailescu, Karol Gietka·Feb 3, 2026

Critical quantum metrology exploits the dramatic growth of the quantum Fisher information near quantum phase transitions to enhance the precision of parameter estimation. This enhancement is commonly associated with a closing energy gap, which causes...

Device variability of Josephson junctions induced by interface roughness

Yu Zhu, Félix Beaudoin, Hong Guo·Feb 3, 2026

As quantum processors scale to large qubit numbers, device-to-device variability emerges as a critical challenge. Superconducting qubits are commonly realized using Al/AlO$_{\text{x}}$/Al Josephson junctions operating in the tunneling regime, where e...

Inducing, and enhancing, many-body quantum chaos by continuous monitoring

Xianlong Liu, Jie-ping Zheng, Antonio M. García-García·Feb 2, 2026

It is intuitively expected, and supported by earlier studies, that many-body quantum chaos is suppressed, or even destroyed, by dissipative effects induced by continuous monitoring. We show here that this is not always the case. For this purpose, we ...

Optimal enhancement of the Overhauser and Solid Effects within a unified framework

Sarfraj Fency, Rangeet Bhattacharyya·Feb 2, 2026

The Overhauser effect (OE) and the Solid effect (SE) are two Dynamic Nuclear Polarization techniques. These two-spin techniques are widely used to create nonequilibrium nuclear spin states having polarization far beyond its equilibrium value. OE is c...

Exceptional phase transition in a single Kerr-cat qubit

Pei-Rong Han, Tian-Le Yang, Wen Ning +4 more·Feb 2, 2026

Exceptional points in non-Hermitian quantum systems give rise to novel genuine quantum phenomena. Recent explorations of exceptional-point-induced quantum phase transitions have extended from discrete-variable to continuous-variable-encoded quantum s...

Quantum vortex channels as Josephson junctions

Natalia Masalaeva, Wyatt Kirkby, Francesca Ferlaino +1 more·Feb 2, 2026

In quantum gases, weak links are typically realized with externally imposed optical potentials. We show that, in rotating binary condensates, quantized vortices in one component form hollow channels that act as self-induced weak links for the other, ...

Phase Dynamics of Self-Accelerating Bose-Einstein Condensates

Maximilian L. D. D. Pellner, Georgi Gary Rozenman·Feb 1, 2026

Self-accelerating Airy matter waves offer a clean setting to access the cubic Kennard phase. Here we reconstruct the relative phase of simulated Airy-shaped Bose-Einstein condensates in free space, a regime approached in microgravity, from interferen...

Single-site dissipation stabilizes a superconducting nonequilibrium steady state in a strongly correlated system
