Fate of the non-Abelian Moore-Read manifold under the non-Hermitian skin effect
Jiaxuan Guo, Simin Nie, Xiting Zhang +1 more·Aug 26, 2026
We study a non-Abelian Moore-Read fractional Chern insulator under a translation-preserving, nonreciprocal deformation that generates the non-Hermitian skin effect under open boundaries. The model combines the imaginary-gauge Hatano-Nelson deformatio...
Simultaneous Digital Communication and Deformation Sensing over a Single Stretchable Interconnect
Yuji Isano, Hiroki Ota·Aug 26, 2026
Stretchable hybrid electronics integrate rigid solid-state electronics with stretchable materials and structures to achieve both high deformability and stable electronic performance. However, most existing systems treat stretchability only as a mecha...
The View from Within: What Can Embedded Observers (Not) Learn?
Tomáš Gonda, Johannes Fankhauser, Gemma De les Coves·Aug 26, 2026
Physics is usually done from a third-person perspective, as if the world were described from outside. Yet, observers are themselves physical systems within the world they observe. Here, we investigate this tension using a toy model of classical parti...
Fault-tolerant $|\sqrt{ \mathrm{T} }\rangle$ state preparation and injection for more efficient fine-grained quantum circuit synthesis
Berat Yenilen, Markus Müller, Manuel Rispler·Aug 26, 2026
Magic-state injection is a standard route to realize universal fault-tolerant quantum computation. Whereas the set of Clifford gates in combination with the non-Clifford T gate is a widely used universal gate set, extending the available set of non-C...
Quantum sampling in hybrid light-matter systems with mixed statistics
Franziska Barkhausen, Laura Ares, Stefan Schumacher +1 more·Aug 26, 2026
Boson sampling is one of the most prominent methods to verify quantum advantage, harnessing the computational complexity of the permanent of a network matrix. Similar quantum sampling problems utilize other expressions for the output probabilities, s...
Update Disturbance-Resilient Analog ReRAM Crossbar Arrays for In-Memory Deep Learning Accelerators
Wooseok Choi, Tommaso Stecconi, Donato Francesco Falcone +14 more·Aug 26, 2026
Resistive memory (ReRAM) technologies with crossbar array architectures hold significant potential for analog AI accelerator hardware, enabling both in-memory inference and training. Recent developments have successfully demonstrated inference accele...
Study of Resistive Switching Dynamics and Memory States Equilibria in Analog Filamentary Conductive-Metal-Oxide/HfOx ReRAM via Compact Modeling
Matteo Galetta, Donato Francesco Falcone, Victoria Clerico +7 more·Aug 26, 2026
Resistive Random Access Memory (ReRAM) devices offer a promising solution for next-generation non-volatile memory and neuromorphic computing systems. Yet, existing compact models fail to capture analog resistive switching behavior of ReRAM devices. T...
The Geometric Phase as a Diagnostic for Driven-Dissipative Oscillators
Zeen Sun, Yuan Shen, Haitao Ding +2 more·Aug 26, 2026
Driven-dissipative quantum oscillators lock their phase, deform their limit cycles, and undergo dissipative phase transitions, yet these behaviors are read from unrelated quantities defined on the same steady-state density matrix. We show that a sing...
Physics-informed quantum algorithms for glueball-like excitations in a $\mathbb{Z}_2$ lattice gauge theory
Dan-Bo Zhang·Aug 26, 2026
Glueball spectroscopy with quantum computing requires both a correlated gauge vacuum and a systematic construction of its low-lying pure-gauge excitations. We develop a physics-informed quantum-computing framework for these tasks in a $(2+1)$-dimensi...
Quantum motility-induced phase separation
Laurin Brunner, Ricard Alert, Reyhaneh Khasseh +1 more·Aug 26, 2026
Motility-induced phase separation (MIPS) describes a central clustering phenomenon in active matter systems where particles spontaneously separate into dense and dilute phases even in the absence of interparticle attractive forces. Recent theoretical...
Phase-sensitive cascade quantum amplifier with nearly noiseless operation
Ilari Lilja, Ekaterina Mukhanova, Michael Perelshtein +5 more·Aug 26, 2026
Phase-sensitive parametric devices enable quadrature-selective amplification with the potential for sub-quantum-limited noise performance. In this work, we investigate the operation of a SQUID-based Josephson Parametric Amplifier (JPA), comparing its...
GNSS-free quantum gravity-aided navigation and fine-scale marine surveying with a strapdown quantum gravimeter
Patrick J. Everitt, Donald H. White, Todd Lyon +19 more·Aug 26, 2026
Global navigation satellite systems (GNSS) are often disrupted or unavailable at sea, and unaided inertial navigation systems (INS) drift without correction. Quantum-sensing-based gravity map matching offers a passive, infrastructure-free aid, but fi...
Certified decoding of quantum LDPC codes
Ragavi Krishnamoorthy, Florian Gerhardt, Johannes Knaute +8 more·Aug 26, 2026
Quantum low-density parity-check (qLDPC) codes reduce the qubit overhead of fault-tolerant quantum computation by an order of magnitude, but their decoding is harder than its classical counterpart: because many physical errors are equivalent up to st...
A universal loss-limited optimum for fixed multi-pass quantum sensing per absorbed photon
Christoph F. Wildfeuer·Aug 26, 2026
Multi-pass schemes send a photon through a sample several times to learn more about it. When the sample rather than the light is scarce, the natural figure of merit is the information gained per photon the object absorbs. We show that one constant fi...
Superextensive learning in quantum reservoirs at the onset of information scrambling
Jonas Freiheit, Francesco Campaioli·Aug 26, 2026
The idea that information processing is optimised near the boundary between order and chaos has emerged as a recurring principle across neuroscience, complex systems, and machine learning. Here we test this hypothesis in quantum many-body systems, nu...
High-Fidelity Entangled States in a Connectivity-Four Fluxonium Quantum Processor
J. Schirk, N. Bruckmoser, S. M. Taubenberger +10 more·Aug 26, 2026
A central challenge in fluxonium-based quantum processors is the extension of the qubit connectivity to two-dimensional lattices compatible with quantum code-error correction. Here, we present a fluxonium quantum processor that employs lumped-element...
Low-leakage superconducting-qubit measurement with sub-100-ns total duration
Peter A. Spring, Adrian L. Hesse, Shiyu Wang +2 more·Aug 26, 2026
Fast, accurate, and low-leakage qubit measurement is a key requirement for quantum error correction. Here, we demonstrate measurement of a superconducting transmon qubit with a total duration of 97(1) ns, defined as the time from the start of the mea...
Interpretable Activation-Selection Neural Networks for Symbolic Regression of Parameter-Dependent Hamiltonian Eigenvalues
Alexander Yu. Kharin, Kirill F. Sheberstov·Aug 26, 2026
Analytical approximations to eigenvalues of parameter-dependent Hamiltonians can provide physical insight that is not readily apparent from numerical diagonalization alone. Here, we introduce an activation-selection network (ASN), a differentiable sy...
Competing Soft Modes and Tunable Multicriticality in a Generalized Two-Mode Quantum Rabi Model
Xiufeng Cao, Ofri Adiv, Neil G. R. Broderick·Aug 26, 2026
Multicritical phenomena play a central role in quantum many-body systems, yet their microscopic origin in light--matter platforms remains largely unexplored. Here we investigate a generalized two-mode quantum Rabi model with independently tunable rot...
The temperature-dependent non-Abelian gauge potential
Zheng-Chuan Wang·Aug 26, 2026
This study shows that the usual time evolution operator can act as a U(1) gauge transformation on the initial wavefuntion. When considering the spin freedom in the system, the time evolution operator corresponds to a non-Abelian SU(2) gauge transform...
