Dependence of Lindbladian spectral statistics on the integrability of no-jump Hamiltonians and the recycling terms
Dingzu Wang, Hao Zhu, Guo-Feng Zhang +1 more·Mar 19, 2026
Spectral statistics probe integrability versus chaos and have recently been extended to Markovian open quantum systems described by Lindbladians, whose quantum-trajectory unraveling decomposes the evolution into no-jump dynamics generated by an effec...
Certifying ergotropy under partial information
Egle Pagliaro, Leonardo Zambrano, Mir Alimuddin +3 more·Mar 19, 2026
Ergotropy, the maximum work extractable from a quantum system, is a central resource in quantum physics. Computing ergotropy is well established when the system state is fully known, but its estimation under partial information remains an open proble...
Time-Multiplexed Distributed Quantum Sensing
Hanbom Yoo, Hyukgun Kwon, Seongjin Hong·Mar 19, 2026
Quantum metrology enables parameter estimation beyond classical limits by exploiting nonclassical resources such as squeezing and entanglement. In distributed quantum sensing, Heisenberg scaling has been extended from $1/N^2$ to $1/(NM)^2$ through en...

Mikolaj Żychowicz, Jakub J. Zakrzewski, Szymon Chorazy +1 more·Mar 19, 2026
Single-Molecule Magnets (SMMs) exhibit slow magnetic relaxation as a result of axial magnetic anisotropy inhibiting spin-phonon transitions. In order to establish a direct link between physical observables and the microscopic theory of magnetic relax...
Dissipative Phase Transition in a Parametrically Amplified Quantum Rabi Model with Two-photon decay
Mingjian Zhu, Han Pu·Mar 18, 2026
We investigate dissipative phase transitions (DPTs) in a parametrically amplified open quantum Rabi model (QRM) with both single- and two-photon decay. In the classical oscillator limit, four composite phases emerge, arising from the possible normal ...
Zeno and anti-Zeno effects in dark-state dynamics under thermal dephasing
Ran Chen, Jiangchuan You, Alexey Vladimirovich Kulagin +2 more·Mar 18, 2026
The quantum Zeno and anti-Zeno effects describe how frequent measurements can either suppress or accelerate quantum dynamics. While extensively studied in various platforms, their manifestation in dark-state dynamics remains largely unexplored. Here ...
Superactivation of genuine multipartite Bell nonlocality from two-party entanglement
Markus Miethlinger, Riccardo Castellano, Pavel Sekatski +1 more·Mar 18, 2026
Characterizing the relation between entanglement and Bell nonlocality is a long-standing open problem, notably challenging in the multipartite case. Here we investigate the effect of superactivation of genuine multipartite nonlocality. Specifically, ...

Postselection induced localization and coherence in quantum walks on heterogeneous networks
Adithya L J, Suraj S Hegde, Chandrakala Meena·Mar 18, 2026
Postselection of quantum trajectories is known effectively introduce nonlinearity into dynamics of open quantum systems. We study the effect of such non-linearity in continuous-time quantum walks (CTQWs) on networks with homogeneous and heterogeneous...
Geometry and restoration of the quantum Mpemba effect beyond weak-coupling regime in the spin-boson model
P. Chirico, G. Di Bello, G. De Filippis +1 more·Mar 18, 2026
Understanding relaxation dynamics in open quantum systems is a central problem in nonequilibrium quantum physics. Here we investigate the quantum Mpemba effect in the spin-boson model. In the weak-coupling Markovian regime we show that the occurrence...
Imaginary Gauge Field and Non-Hermitian Topological Transition Emerging Through Attenuation-Gauge Duality in Conservative Systems
Haoran Nie, Chaoran Jiang, Xiangying Shen +1 more·Mar 18, 2026
Non-Hermitian physics traditionally relies on active gain--loss modulation or non-reciprocal couplings, which often introduce significant complexity, compromise stability, and offer very limited scalability in conservative systems. Here we propose an...
Quantum Simulation of Non-Hermitian Linear Response via Schrödingerization
Jeongbin Jo·Mar 18, 2026
Linear response theory and Green's functions provide a universal framework for understanding dynamical correlations in strongly correlated open quantum systems. While the theoretical foundation for non-Hermitian linear response has been recently esta...

Eric J. Sung, Charles A. Stafford·Mar 17, 2026
In a recent paper arXiv:2205.06279, Danielson et al. demonstrated that the mere presence of a black hole causes universal decoherence of quantum superpositions (dubbed the DSW decoherence). This result has profound implications for the interplay of q...
