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...
