Measurement-and Feedback-Driven Non-Equilibrium Phase Transitions on a Quantum Processor
Zhiyi Wu, Xuandong Sun, Songlei Wang +8 more·Dec 8, 2025
Mid-circuit measurements and feedback operations conditioned on the measurement outcomes are essential for implementing quantum error-correction on quantum hardware. When integrated in quantum many-body dynamics, they can give rise to novel non-equil...
Coherence-limited digital control of a superconducting qubit using a Josephson pulse generator at 3 K
M. A. Castellanos-Beltran, A. J. Sirois, L. Howe +4 more·Dec 8, 2025
Compared to traditional semiconductor control electronics (TSCE) located at room temperature, cryogenic single flux quantum (SFQ) electronics can provide qubit measurement and control alternatives that address critical issues related to scalability o...
Strong-field regime within effective field theory
Sebastián Franchino-Viñas, Jérémie Quevillon, Diego Saviot·Dec 8, 2025
Building upon the Covariant Derivative Expansion, we develop a method to compute effective actions that is able to capture non-perturbative effects induced by strong background fields. We demonstrate the method in scalar QED, by deriving the full sec...
Exchange Symmetry in Multiphoton Quantum Interference
Shreya Kumar, Alex E Jones, Daniel Bhatti +1 more·Dec 8, 2025
Photons are bosons, and yet, when prepared in specific entangled states, they can exhibit non-bosonic behaviour. While this phenomenon has so far been studied in two-photon systems, exchange symmetries and interference effects in multi-photon scenari...
Vortex leapfrogging and superfluid dissipation mechanisms in a fluid of light
Myrann Baker-Rasooli, Nathan du Toit, Nicolas Pavloff +1 more·Dec 8, 2025
We report the experimental observation of vortex leapfrogging in a two-dimensional fluid of light. By imprinting two vortex-antivortex pairs and tracking their real-time evolution through phase-resolved imaging, we observe a dynamics that is accurate...
Comparing quantum channels using Hermitian-preserving trace-preserving linear maps: A physically meaningful approach
Arindam Mitra, Jatin Ghai·Dec 8, 2025
In quantum technologies, quantum channels are essential elements for the transmission of quantum states. The action of a quantum channel usually introduces noise in the quantum state and thereby reduces the information contained in it. These are math...
Fast-feedback protocols for calibration and drift control in quantum computers
Alicia B. Magann, Nathan E. Miller, Robin Blume-Kohout +2 more·Dec 8, 2025
We introduce two classes of lightweight, adaptive calibration protocols for quantum computers that leverage fast feedback. The first enables shot-by-shot updates to device parameters using measurement outcomes from simple, indefinite-outcome quantum ...
Nonlinear Quantum Mechanics and Artificial Intelligence
Jonathan Oppenheim·Dec 8, 2025
We examine a criterion for relativistic covariance of nonlinear quantum field theory recently proposed by GPT-5 and published in Physics Letters B. We show that this criterion inadvertently tests a different property -- locality of the Hamiltonian --...
LUNA: LUT-Based Neural Architecture for Fast and Low-Cost Qubit Readout
M. A. Farooq, G. Di Guglielmo, A. Rajagopala +3 more·Dec 8, 2025
Qubit readout is a critical operation in quantum computing systems, which maps the analog response of qubits into discrete classical states. Deep neural networks (DNNs) have recently emerged as a promising solution to improve readout accuracy . Prior...
Trapped Fermions Through Kolmogorov-Arnold Wavefunctions
Paulo F. Bedaque, Jacob Cigliano, Hersh Kumar +2 more·Dec 8, 2025
We investigate a variational Monte Carlo framework for trapped one-dimensional mixture of spin-$\frac{1}{2}$ fermions using Kolmogorov-Arnold networks (KANs) to construct universal neural-network wavefunction ansätze. The method can, in principle, ac...
Strongly driven cavity quantum electrodynamical-optomechanical hybrid system
Xuxin Wang, Jiahe Pan, Tobias J. Kippenberg +1 more·Dec 8, 2025
Hybrid quantum systems harness the distinct advantages of different physical platforms, yet their integration is not always trivial due to potential incompatibilities in operational principles. Here, we theoretically propose and demonstrate a scheme ...
Statistical properties of quantum jumps between macroscopic states of light: reading an operational coherence record
Th. K. Mavrogordatos·Dec 8, 2025
We propose an experimental apparatus to reveal the quantum coherence manifested in downward quantum jumps of amplitude bistability. The underlying coherent superposition of macroscopic quantum states is translated into the statistical properties of t...
Real-time collisions of fractional charges in a trapped-ion Jackiw-Rebbi field theory
Alan Kahan, Pablo Viñas, Torsten V. Zache +1 more·Dec 8, 2025
We propose and analyze a trapped-ion quantum simulator of the Jackiw-Rebbi model, a paradigmatic quantum field theory in (1+1) dimensions where solitonic excitations of a scalar field can bind fermionic zero modes leading to fractionally-charged exci...
Strong zero modes in integrable spin-S chains
Fabian H. L. Essler, Paul Fendley, Eric Vernier·Dec 8, 2025
We derive exact strong zero mode (ESZM) operators for integrable spin-S chains with open boundary conditions and a boundary field. Their locality properties are generally weaker than in the previously known cases, but they still imply infinite cohere...
A scalable and real-time neural decoder for topological quantum codes
Andrew W. Senior, Thomas Edlich, Francisco J. H. Heras +21 more·Dec 8, 2025
Fault-tolerant quantum computing will require error rates far below those achievable with physical qubits. Quantum error correction (QEC) bridges this gap, but depends on decoders being simultaneously fast, accurate, and scalable. This combination of...
The Native Spiking Microarchitecture: From Iontronic Primitives to Bit-Exact FP8 Arithmetic
Zhengzheng Tang·Dec 8, 2025
The 2025 Nobel Prize in Chemistry for Metal-Organic Frameworks (MOFs) and recent breakthroughs by Huanting Wang's team at Monash University establish angstrom-scale channels as promising post-silicon substrates with native integrate-and-fire (IF) dyn...
Grand Canonical vs Canonical Krylov Complexity in Double-Scaled Complex SYK Model
Stefan Forste, Yannic Kruse, Saurabh Natu·Dec 8, 2025
We consider the complex SYK model in the double-scaling limit. We obtain the transfer matrix for the grand canonical ensemble and symmetrize it. In the (n,Q)- basis of chord states, the grand canonical transfer matrix is block diagonal, where each bl...
Brazilian Twin Photons 32nd anniversary
Renné Medeiros de Araújo, Raphael César Souza Pimenta, Lucas Marques Fagundes +4 more·Dec 8, 2025
We present a historical review of the development and impact of spontaneous parametric down-conversion (SPDC) in Brazil, marking over three decades since the first twin-photon experiments were performed in the country. This article traces the pioneer...
A Framework for Data Valuation and Monetisation
Eduardo Vyhmeister, Bastien Pietropaoli, UdoBub +2 more·Dec 8, 2025
As organisations increasingly recognise data as a strategic resource, they face the challenge of translating informational assets into measurable business value. Existing valuation approaches remain fragmented, often separating economic, governance, ...
Single-Operation Rydberg Phase Gates via Dynamic Population Suppression
Sebastian C. Carrasco, Jabir Chathanathil, Svetlana A. Malinovskaya +2 more·Dec 8, 2025
We propose a versatile control protocol based on modulated zero-pulse-area fields that dynamically suppresses Rydberg excitation while retaining Rydberg-Rydberg interactions as an entangling phase resource. This mechanism enables single-step, perfect...
