One Key Good, L Keys Better: List Decoding Meets Quantum Privacy Amplification
Prateek P. Kulkarni·Mar 18, 2026
We introduce list privacy amplification (LPA), a relaxation of the final step of quantum key distribution (QKD) in which Alice and Bob extract a list of $L$ candidate keys from a raw string correlated with an eavesdropper Eve, with the guarantee that...
Quantum Field Approaches to Chemical Systems
Reza Karimpour, Matteo Gori, Alexandre Tkatchenko·Mar 18, 2026
Quantum-matter theory (QMT), based on the Schrödinger or Dirac equations, is firmly established for both intra- and intermolecular interactions. However, there are two key issues with QMT. First, its applicability to large molecular complexes is hind...
Quantum theory over dual-complex numbers
P. Arrighi, D. Bakircioglu, N. L. Houyet·Mar 18, 2026
We take quantum theory and replace $\mathbb{C}$ by $\mathbb{C}[\varepsilon]$ where $\varepsilon^2=0$, i.e. we extend quantum theory to the ring of dual complex numbers. The aim is to develop a common language in which to treat continuous quantum phys...
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...
On global dynamics for damped driven Jaynes-Cummings equations
A. I. Komech, E. A. Kopylova·Mar 18, 2026
The article concerns damped driven Jaynes-Cummings equation which describes quantised one-mode Maxwell field coupled to a two-level molecule. We consider a broad class of damping and pumping which are polynomial in the creation and annihilation opera...
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...
On dynamical semigroup for damped driven Jaynes-Cummings equations
A. I. Komech, E. A. Kopylova·Mar 18, 2026
The article addresses the damped driven Jaynes-Cummings for quantised one-mode Maxwell field coupled to a two-level molecule. We consider a broad class of damping and pumping which are polynomial in the creation and annihilation operators. Our main r...
Anyon-Induced Criticality and Dynamical Stability in Non-Hermitian Many-Body Systems
Yi Qin, Yee Sin Ang, Linhu Li +1 more·Mar 18, 2026
We show that anyonic statistics fundamentally reshapes non-Hermitian many-body physics by intrinsically breaking pseudo-Hermiticity, leading to a unique real-complex spectral transition with characteristically dense states in Im$E$. This anyon-induce...
General circuit compilation protocol into partially fault-tolerant quantum computing architecture
Tomochika Kurita·Mar 18, 2026
As we are entering an early-FTQC era, circuit execution protocols with logical qubits and certain error-correcting codes are being discussed. Here, we propose a circuit execution protocol for the space-time efficient analog rotation (STAR) architectu...
Stabilizing correlated pair tunneling of spin-orbit-coupled bosons in a non-Hermitian driven double well
Miaoqian Lu, Xinzhou Guan, Mohan Xia +4 more·Mar 18, 2026
We present an analytical framework for stabilizing second-order correlated tunneling of two spin-orbit-coupled bosons in a periodically driven non-Hermitian double-well potential. By combining Floquet theory with multiple-scale asymptotic analysis, w...
Anomalous localization and duality in non-Hermitian quasiperiodic models
Wenzhi Wang, Tianyu Li, Wei Yi·Mar 18, 2026
Boundary conditions can have dramatic impact in non-Hermitian systems, as exemplified by the non-Hermitian skin effect. Focusing on one-dimensional non-Hermitian quasiperioidic lattices, we show that the interplay of quasiperiodicity and the non-Herm...
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...
Engineering strong coupling with molecular coatings in optical nanocavities
Athul S. Rema, Adrián E. Rubio López, Felipe Herrera·Mar 18, 2026
Quantum emitters near the surface of silver nanoparticles undergo Rabi oscillations in electronic population dynamics due to strong coupling with near-field multipole modes that are not radiative. Low-frequency nanoparticle dipole modes are radiative...
Reinforcement Learning for Fast and Robust Longitudinal Qubit Readout
Yiming Yu, Yuan Qiu, Xinyu Zhao +2 more·Mar 18, 2026
Longitudinal coupling offers a compelling pathway for quantum nondemolition (QND) readout, but pulse design is constrained by hardware limitations such as the coupling strength and the photon number required to stay within the linear regime. We devel...
Efficient and flexible preparation of photonic NOON states in a superconducting system
Dong-Sheng Li, Yi-Hao Kang, Zhi-Cheng Shi +3 more·Mar 18, 2026
The NOON states play a critical role as physical resources in quantum information processing and quantum metrology, yet their preparation efficiency and applicability are often constrained by complicated operational procedures or the requirement for ...
Noise-resilient nonadiabatic geometric quantum computation for bosonic binomial codes
Dong-Sheng Li, Yang Xiao, Yu Wang +5 more·Mar 18, 2026
The binomial code is renowned for its parity-mediated loss immunity and loss-error recoverability, while geometric phases are widely recognized for their intrinsic resilience against noise. Capitalizing on their complementary merits, we propose a noi...
Comment on: "Coherent perfect absorption: Zero reflection without linewidth suppression"
Rui-Chang Shen, Jie Li·Mar 18, 2026
A recent paper, Phys. Rev. Research 8, 013261 (2026), claims that the polaromechanical normal-mode splitting (NMS) measured in Nat. Commun. 16, 5652 (2025) is not true based on their two results: $i$) there is no true splitting in the linear-scale sp...
Allocating Access to Quantum Computing: A Legal-Ethical Framework
Benedict Lane, Anushka Mittal, A. Torres-Knoop·Mar 18, 2026
Along with the increased availability and capabilities of quantum computers comes the core question: how can access to quantum computing be allocated in a responsible way? This report introduces a general legal-ethical framework that providers of acc...
Binary Latent Protein Fitness Landscapes for Quantum Annealing Optimization
T. Hy·Mar 18, 2026
We propose Q-BIOLAT, a framework for modeling and optimizing protein fitness landscapes in binary latent spaces. Starting from protein sequences, we leverage pretrained protein language models to obtain continuous embeddings, which are then transform...
Dynamical Drexhage Effect: Amplified Emission in Time-Modulated Electromagnetic Environments
Juan Carlos Obeso Jureidini, Michael Reitz, Piper Fowler-Wright +4 more·Mar 17, 2026
We investigate the effect of nonrelativistic motion on the emission dynamics of a dipole emitter moving next to a reflecting interface. Within the formalism of macroscopic QED, we obtain a general equation of motion for the dipole amplitude in terms ...
