Room-Temperature Electrical Readout of Spin Defects in van der Waals Materials
Shihao Ru, Liheng An, Haidong Liang +14 more·Nov 12, 2025
Negatively charged boron vacancy ($\mathrm{V_B^-}$) in hexagonal boron nitride (hBN) is the most extensively studied room-temperature quantum spin system in two-dimensional (2D) materials. Nevertheless, the current effective readout of $\mathrm{V_B^-...
Quantum-classical gravity distinction in reservoir-engineered massive quantum system
Ziqian Tang, Zizhao Han, Zikuan Kan +4 more·Nov 12, 2025
Massive quantum systems have emerged as compelling tabletop interface-systems for testing the quantum nature of gravity. However, conventional schemes that focus on directly using gravity to induce entanglement suffer from overwhelming environmental ...
Information Processing in Quantum Thermodynamic Systems: an Autonomous Hamiltonian Approach
Shou-I Tang, Emery Doucet, Akram Touil +2 more·Nov 12, 2025
Extending the quantum formulation of [Phys. Rev. X 3, 041003 (2013)] to a more general setting for studying the thermodynamics of information processing including initial correlations, we generalize the second law of thermodynamics to account for inf...
Complex Eigenvalues in a pseudo-Hermitian \b{eta}-Laguerre ensemble
Cleverson Andrade Goulart, Gleb Oshanin, Mauricio Porto Pato·Nov 12, 2025
Non-Hermitian PT-symmetric models have been extensively studied in recent years. Following the seminal work that reduced classical random matrix ensembles to a tridiagonal form, several efforts have aimed to generalize this framework to non-Hermitian...
Space-Time Optimisations for Early Fault-Tolerant Quantum Computation
Sanaa Sharma, Prakash Murali·Nov 12, 2025
Fault-tolerance is the future of quantum computing, ensuring error-corrected quantum computation that can be used for practical applications. Resource requirements for fault-tolerant quantum computing (FTQC) are daunting, and hence, compilation techn...
PQC-LEO: An Evaluation Framework for Post-Quantum Cryptographic Algorithms
Callum Turino, William J. Buchanan, O. Lo +1 more·Nov 12, 2025
Advances in quantum computing threaten digital communication security by undermining the foundations of current public-key cryptography through Shor's quantum algorithm. This has driven the development of Post-Quantum Cryptography (PQC), a new set of...
Modelling many-body quantum dynamics with stochastic trajectories: a critical test on the Tavis-Cummings model
A. Leonau, S. Chuchurka, V. Sukharnikov +2 more·Nov 11, 2025
We critically explore the applicability of a recently proposed framework to sample the quantum dynamics of a many-body quantum system interacting with light by stochastic trajectories, applying it to the closed and open Tavis-Cummings model (TCM). Th...
Cold-Atom Buoy: A Differential Magnetic Sensing Technique in Cold Quadrupole Traps
Árpád Kurkó, Dávid Nagy, Alexandra Simon +7 more·Nov 11, 2025
We present a differential technique for vector magnetic sensing based on a cold-atom cloud in a magnetic quadrupole trap. An external homogeneous magnetic field displaces the trap center in a direction and magnitude proportional to the field. By reve...
Continuous-time quantum walks on a defective lattice: boosting the spreading of delocalized states through Parrondo's strategy
João V. Cordeiro, Eduardo I. Duzzioni, Edgard P. M. Amorim·Nov 11, 2025
We investigate the quantum transport of delocalized states in continuous-time quantum walks (CTQWs) on a one-dimensional lattice containing a single defect. The defect is modeled by assigning complex-valued hopping amplitudes to the edges that connec...
Probing short-range gravity using quantum reflection
J. Boynewicz, C. A. Sackett·Nov 11, 2025
Quantum reflection occurs when ultra-cold atoms are incident on a material surface with sufficiently low velocity. The reflecting matter wave can interfere with the incident wave to form a detectable pattern, and this pattern contains information abo...
Exact Floquet dynamics of strongly damped driven quantum systems
Konrad Mickiewicz, Valentin Link, Walter T. Strunz·Nov 11, 2025
We present an approach for efficiently simulating strongly damped quantum systems subjected to periodic driving, employing a periodic matrix product operator representation of the influence functional. This representation enables the construction of ...
Topological subregions in Chern Simons theory and topological string theory
Gabriel Wong·Nov 11, 2025
The standard, gapped entanglement boundary condition in Chern Simons theory breaks the topological invariance of the theory by introducing a complex structure on the entangling surface. This produces an infinite dimensional subregion Hilbert space, a...
Hybrid Atomistic-Parametric Decoherence Model for Molecular Spin Qubits
Katy Aruachan, Sanoj Raj, Yamil J. Colón +2 more·Nov 11, 2025
Solid-state molecular qubits with open-shell ground states have great potential for addressability, scalability, and tunability, but understanding the fundamental limits of quantum coherence in these systems is challenging due to the complexity of th...
Experimental Realization of Thermal Reservoirs with Tunable Temperature in a Trapped-Ion Spin-Boson Simulator
Visal So, Mingjian Zhu, Midhuna Duraisamy Suganthi +5 more·Nov 11, 2025
We propose and demonstrate an experimental scheme to engineer thermal baths with independently tunable temperatures and dissipation rates for the motional modes of a trapped-ion system. This approach enables robust thermal-state preparation and quant...
Fractal structure of multipartite entanglement in monitored quantum circuits
Vaibhav Sharma, Erich J Mueller·Nov 11, 2025
We analyze the distribution of multipartite entanglement in states produced in a one-dimensional random monitored quantum circuit where local Clifford unitaries are interspersed with single-site measurements performed with a probability $p$. This cir...
Universality and weak-ergodicity breaking in quantum quenches
Guido Giachetti, Andrea Solfanelli, Nicolò Defenu·Nov 11, 2025
Sudden quenches in quantum many-body systems often lead to dynamical evolutions that unveil surprising physical behaviors. In this work, we argue that the emergence of weak ergodicity breaking following quantum quenches in certain local many-body sys...
Variational Method in Quantum Field Theory
Arthur Hutsalyuk, Márton Lájer, Giuseppe Mussardo +1 more·Nov 11, 2025
We develop a variational framework for addressing two-dimensional non-integrable quantum field theories through the exact structure of their integrable counterparts. Concentrating on the $\varphi^4$ Landau-Ginzburg model, we use the analytical Vacuum...
Quantum tunneling from excited states in the steadyon picture
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser·Nov 11, 2025
Recent developments in the understanding of real-time path integrals led to the development of the ``steadyon picture'' for the semi-classical calculation of quantum tunneling rates. We discuss tunneling out of a generic localized initial state in th...
Path integral predictions for pre-asymptotic false vacuum decay
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser·Nov 11, 2025
When tunneling occurs out of generic initial states, a significant fraction of probability is lost at early times during which the dynamics is governed by excited resonance states. However, first-principles analyses based on path integrals have only ...
