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...
Quantum skyrmion parallelism via metasurface-tailored high-dimensional entanglement
Pedro Ornelas, Ramona Bedford, Fazilah Nothlawala +6 more·Aug 26, 2026
Quantum skyrmions are topological structures that have garnered significant interest due to their demonstrated robustness and versatility across diverse optical platforms. However, existing approaches for their generation are limited to producing pre...
Affine-Profile Stabilizer Thresholds for Magic in Codeword-Stabilized Quantum Codes
Li-Yi Hsu, En-Jui Kuo·Aug 26, 2026
Codeword-stabilized quantum codes give a unified graph-state description of stabilizer and nonadditive quantum error-correcting codes. Although each individual CWS word state is stabilizer, coherent superpositions of different word states can be nons...
Non-Hermitian topological Euler insulators
Longwen Zhou·Aug 26, 2026
Topological Euler insulators emerge in multiband systems with real Bloch Hamiltonians and wavefunctions. Their fragile topologies are characterized by the Euler class of degenerate bands and protected by the $PT$ or $C_2T$ symmetry in two dimensions,...
GPU-Accelerated Quantum Annealing-Inspired UAV Path Planning for Smart Agriculture
Maho Hirahara, Aohan Li·Aug 26, 2026
Traditional path planning methods are often constrained by local optima, limited scalability, and slow convergence, which significantly restrict their effectiveness in solving large-scale problems. To address these limitations, this paper shifts the ...
The Pauli Lightcone: Information-Theoretic Error Mitigation Beyond the Autocorrelation
Paolo D'Alberto·Aug 26, 2026
We introduce the wavemap: a spatial portrait of noise effects that assigns each site a per-noise-level arrival delay l_γ(v) and cross-entropy loss L_γ(v). These observables are exact at the lightcone frontier, where bond dimension χis small and the s...
Dynamical Consequences of Nontrivial Topology of Molecular Conical Intersections
Indranil Ghosh, Kush Banker, Gregory S. Engel·Aug 25, 2026
The topology of the electronic structure for an avoided crossing and a conical intersection (CI) is different and is characterized by the presence of the geometric phase in the electronic wavefunction in the latter. Using the linear Jahn-Teller model...
Next-generation O-RAN Edge: Energy-aware Joint Placement and Migration of Cloud-Native Functions
Nguyen Phuc Tran, Brigitte Jaumard, Oscar Delgado·Aug 25, 2026
The transition toward Open Radio Access Networks (O-RANs) is reshaping how cellular infrastructure is deployed, managed, and optimized. This paper investigates the energy-aware joint placement and migration of cloud-native functions (CNFs) in an O-RA...
HORIZON: A Read-Efficient Firmware for DNA Storage with Horizontal Layout
Alex Sensintaffar, Roop Kiran, Yang Chen +2 more·Aug 25, 2026
DNA storage is a promising medium for long-term archiving, but its read performance is limited by coarse-grained random access. Existing random-access DNA storage designs suffer from high read amplification because their sequential layouts co-locate ...
Certified Randomness without Structure Against Shallow-Query Adversaries
Dakshita Khurana, Bhaskar Roberts, Avishay Tal·Aug 25, 2026
In a recent breakthrough, Yamakawa and Zhandry (J. ACM 2024) constructed a proof of quantumness in the quantum random oracle model (QROM) in which the quantum prover samples a codeword preimage of a publicly computable function H. They conjectured th...
Reliability Limits and Decoding for Partial Nanopore Protein Rereads With Persistent State
Hongbin Ni, Haofan Dong, Ozgur B. Akan·Aug 25, 2026
Repeated observations of one physical object need not constitute independent channel uses. We model partial nanopore protein rereads as a finite-alphabet channel with canonical content, persistent readout, and pass-local coverage and synchronization....
Masked Differential-linear Distinguishers and Quantum Approaches
Shobhit Pandey, Sarbani Sen, Debajyoti Bera +1 more·Aug 25, 2026
We introduce masked auto-correlation, a new primitive for the cryptanalysis of symmetric-key primitives, together with a quantum attack pipeline built on it. For a permutation $f$, output masks $α,β$, and an input difference $w$, masked auto-correlat...
Graphix: A software framework for Measurement-Based Quantum Computation
Mateo Uldemolins, Pranav Nair, Emlyn Graham +3 more·Aug 25, 2026
Measurement-based quantum computing (MBQC) is a powerful model for quantum computation, but dedicated software tools that bridge its theoretical foundations with practical research workflows remain limited. We present Graphix, a software framework fo...
Scalable Lindblad Noise Learning via Stochastic Tensor-Network Simulation
Alejandro R. Ramos Ramos, Maximilian Fröhlich, Aaron Sander +4 more·Aug 25, 2026
Learning dissipation rates in large-scale open quantum systems is a major obstacle for near-term quantum technologies, as existing Lindblad estimation methods are typically limited to small system sizes due to the computational complexity of repeated...
A Dynamic-Kernel/QPacket Executable for Quantum Repeater Chains in Q2NS/ns-3
Adam Pearson, Marcello Caleffi, Angela Sara Cacciapuoti·Aug 25, 2026
The Quantum Internet operates on entanglement, a non-local, non-copyable, stateful network resource, which motivates protocol organization beyond classical layering. We present a first executable specialization of the Dynamic Kernel/QPacket logic fro...
A unified dynamical modeling framework for cruise control and adaptive cruise control
Mingfeng Shang, Shian Wang·Aug 24, 2026
Adaptive cruise control (ACC) vehicles are the first generation of automated vehicles. While fully automated vehicles are expected to benefit traffic flow, field experiments have shown that commercially available ACC vehicles may instead degrade it b...
Dissipation-induced Sachdev-Ye-Kitaev physics in many-body cavity quantum electrodynamics
Pietro Pacchioni, Filippo Ferrari, Vincenzo Savona +1 more·Aug 24, 2026
We show that cavity quantum electrodynamics (QED) devices can realize dissipative Sachdev-Ye-Kitaev (SYK) physics, a paradigmatic setting for quantum chaos in open many-body systems. Ultracold fermions with disordered, all-to-all cavity-mediated inte...
