Nonstabilizerness in open XXZ spin chains: Universal scaling and dynamics
Doru Sticlet, Balázs Dóra, Dominik Szombathy +2 more·Apr 15, 2025
Magic, or nonstabilizerness, is a crucial quantum resource, yet its dynamics in open quantum systems remain largely unexplored. We investigate magic in the open XXZ spin chain under either boundary gain and loss, or bulk dephasing using the stabilize...
Experimental Observation of Single- and Multisite Matter-Wave Solitons in an Optical Accordion Lattice
Robbie Cruickshank, Francesco Lorenzi, Arthur La Rooij +5 more·Apr 15, 2025
We report the experimental observation of discrete bright matter-wave solitons with attractive interaction in an optical lattice. Using an accordion lattice with adjustable spacing, we prepare a Bose-Einstein condensate of cesium atoms across a defin...
Measuring coherent dynamics of a superconducting qubit in an open waveguide
Aidar Sultanov, Evgeniya Mutsenik, Matthias Schmelz +5 more·Apr 15, 2025
We measured the relaxation and decoherence rates of a superconducting transmon qubit in a resonator-free setting. In our experiments, the qubit is coupled to an open coplanar waveguide such that the transmission of microwaves through this line depend...
Room-temperature hybrid 2D-3D quantum spin system for enhanced magnetic sensing and many-body dynamics
Haoyu Sun, Pei Yu, Xu Zhou +10 more·Apr 15, 2025
Advances in hybrid quantum systems and their precise control are pivotal for developing advanced quantum technologies. Two-dimensional (2D) materials with optically accessible spin defects have emerged as a promising platform for building integrated ...
Q-Cluster: Quantum Error Mitigation Through Noise-Aware Unsupervised Learning
Hrushikesh Pramod Patil, Dror Baron, Huiyang Zhou·Apr 15, 2025
Quantum error mitigation (QEM) is critical in reducing the impact of noise in the pre-fault-tolerant era, and is expected to complement error correction in fault-tolerant quantum computing (FTQC). In this paper, we propose a novel QEM approach, Q-Clu...
Algorithmic Advances Towards a Realizable Quantum Lattice Boltzmann Method
Apurva Tiwari, Jason Iaconis, Jezer Jojo +4 more·Apr 15, 2025
The Quantum Lattice Boltzmann Method (QLBM) is one of the most promising approaches for realizing the potential of quantum computing in simulating computational fluid dynamics. Many recent works mostly focus on classical simulation, and rely on full ...
Post-Variational Ground State Estimation via QPE-Based Quantum Imaginary Time Evolution
Nora M. Bauer, G. Siopsis·Apr 15, 2025
Quantum phase estimation (QPE) plays a pivotal role in many quantum algorithms, offering provable speedups in applications such as Shor's factoring algorithm. While faulttolerant quantum algorithms for combinatorial and Hamiltonian optimization often...
Dynamical Casimir effect in superconducting cavities: from photon generation to universal quantum gates
F. Lombardo, P. I. Villar·Apr 15, 2025
This chapter explores various aspects of the Dynamical Casimir Effect (DCE) and its implications in the context of circuit quantum electrodynamics (cQED). We begin by reviewing the origin and fundamental properties of the DCE, including three equival...
Assessing Tensor Network Quantum Emulators for Hamiltonian Simulation of Pharmaceutical Molecules: Challenges and Limitations in Drug Discovery Applications
Marek Kowalik, E. Michael, Peter Pog'any +1 more·Apr 15, 2025
Quantum computing holds promise for revolutionizing computational chemistry simulations, particularly in drug discovery. However, current quantum hardware is limited by noise and scale, necessitating bridging technologies. This study provides an init...
Iterative Linear Quadratic Regulator for Quantum Optimal Control
D. Heimann, Felix Wiebe, Tahereh Abad +4 more·Apr 15, 2025
Quantum optimal control for gate optimization aims to provide accurate, robust, and fast pulse sequences to achieve gate fidelities on quantum systems below the error correction threshold. Many methods have been developed and successfully applied in ...
Heat operator approach to quantum stochastic thermodynamics in the strong-coupling regime
Sheikh Parvez Mandal, Mahasweta Pandit, Khalak Mahadeviya +2 more·Apr 14, 2025
Heat exchanged between an open quantum system and its environment exhibits fluctuations that carry crucial signatures of the underlying dynamics. Within the well-established two-point measurement scheme, we identify a 'heat operator,' whose moments w...
Non-Hermitian Multipole Skin Effects Challenge Localization
Jacopo Gliozzi, Federico Balducci, Taylor L. Hughes +1 more·Apr 14, 2025
We study the effect of quenched disorder on the non-Hermitian skin effect in systems that conserve a U(1) charge and its associated multipole moments. In particular, we generalize the Hatano-Nelson argument for a localization transition in disordered...
High-Resolution Casimir Force Sensing Across a Superconducting Transition
Minxing Xu, Robbie J. G. Elbertse, Ata Keşkekler +4 more·Apr 14, 2025
The Casimir effect and superconductivity are foundational quantum phenomena whose interplay is an open question in physics, with significant implications for electron physics, quantum gravity, and high-temperature superconductivity. Determining how C...
The stellar decomposition of Gaussian quantum states
Arsalan Motamedi, Yuan Yao, Kasper Nielsen +4 more·Apr 14, 2025
We introduce the stellar decomposition, a novel method for characterizing non-Gaussian states produced by photon-counting measurements on Gaussian states. Given an $(m+n)$-mode Gaussian state $G$, we express it as an $(m+n)$-mode "Gaussian core state...
Purcell-enhanced quantum adsorption
Dennis P. Clougherty·Apr 14, 2025
Cold atoms can adsorb to a surface with the emission of a single phonon when the binding energy is sufficiently small. The effects of phonon damping and adsorbent size on the adsorption rate in this quantum regime are studied using the multimode Rabi...

Iason Tsiamis, Georgios Doultsinos, Andreas F. Tzortzakakis +5 more·Apr 14, 2025
Rydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an atom chip, depending on the sign of the dipole moment of the Rydberg-S...
