Brownian Motion in Orthogonal and Symplectic Groups
Zhiyang Tan, Piet W. Brouwer·Jul 6, 2026
Matrix Brownian motion provides a powerful framework for studying crossover ensembles in quantum chaos and quantum transport, as well as thermalization and information scrambling in many-body dynamics. Here, we develop a unified diagrammatic framewor...
Transmon Phase Gates Controlled by Superconducting Soliton DAC
Derek Reitz, Tony X. Zhou, Aditya Sharma +10 more·Jul 6, 2026
We introduce a superconducting digital-to-analog converter (DAC) that filters control noise, provides native multiplexing, performs quantum gates in nanoseconds, and can be controlled by CMOS. This is achieved by transducing a trapezoidal drive pulse...
Emergent cosmology and gravity from quantum time?
Ovidiu Cristinel Stoica·Jul 6, 2026
Macroscopic observables allow the recovery of intrinsic dynamics from stationary quantum states. I show that, by interpreting the squared amplitude as the probability density for each definite value of intrinsic time, a curvature emerges in the time ...
Geometric Characteristics of Subproblems in Ising-Machine-Assisted Large Neighborhood Search
Masashi Yamashita, Shu Tanaka·Jul 6, 2026
Large-scale quadratic unconstrained binary optimization (QUBO) formulations of constrained combinatorial optimization problems often exceed the input-size limit of present Ising machines or suffer from degraded solution quality as the number of binar...
Investigating Role of Electron Correlation Effects via Triple Excitations for Precise Evaluation of Energies and Hyperfine Structure Constants in $^{23}$Na
Vaibhav Katyal, B. K. Sahoo·Jul 6, 2026
Accurate determination of hyperfine structure constants in atomic systems provides important insight into the interplay of electron correlation and relativistic effects in the nuclear region. Although sodium (Na) is a relatively light atom, previous ...
Canonical quantization of neurons
Alexander He, Nana Liu, Mark M. Wilde·Jul 6, 2026
Canonical quantization provides a systematic procedure for constructing quantum models from classical Hamiltonians. Here, we apply this principle to a fundamental computational primitive of machine learning: the neuron. Specifically, by viewing a neu...
Quantum Hashing via Constrained Rydberg Many-Body Dynamics
Han-Chao Chen, Xin Liu, Zheng-Yuan Zhang +2 more·Jul 6, 2026
In this Letter, we show that constrained many-body dynamics in Rydberg atom arrays naturally gives rise to a quantum hashing mechanism. By encoding ternary strings into deterministic trajectories in the state space, the classical information space is...
LLM for the development of FCM
Alexis Kafantaris·Jul 6, 2026
This article is about the development of a fuzzy cognitive map using a local large language model. In the light of recent advances it is evident that large language models, and even local large language models are capable of extracting quantities fro...
Extending the Bloch sphere model to an N-qubit system
Francisco Piñero, Cristian Franco, Hernán I. de la Cruz +5 more·Jul 6, 2026
The Bloch sphere is an elegant tool for representing single-qubit states. However, a widely accepted generalization for multi-qubit systems with entanglement remains absent. We propose a novel geometric model extending the Bloch sphere representation...
Super-molasses returns: All optical near-resonance laser cooling and trapping of neutral atoms from background vapor
Matt Himsworth, Chester Camm, Max Carey +12 more·Jul 6, 2026
Laser cooled and trapped atoms have been the workhorse of atomic physics for the past four decades. The predominant method has been the highly versatile Magneto-Optical Trap. We describe an alternative laser trap involving a simple geometry of collim...
Contraction and Expansion Values of Quantum Channels
Ruben Ibarrondo, Mikel Sanz·Jul 6, 2026
The contraction coefficient of the trace distance is a central tool in quantum information, quantifying how strongly a quantum channel degrades the distinguishability of states. However, being an extremal ratio, it captures only the most optimistic b...
Noise-limited secret key agreement with twin optical physically unclonable functions
Georgios M. Nikolopoulos·Jul 6, 2026
We investigate the use of twin optical fingerprints derived from correlated physical unclonable functions (PUFs), as a hardware-based platform for cryptographic key generation and distribution. Each fingerprint is associated with a random, yet reprod...
How Hard Is Quantum Advantage? A Cloud Microphysics Stress Test for Variational Quantum Models
Felix Herbort, Ellen Sarauer, Daniel Ohl de Mello +7 more·Jul 6, 2026
Quantum machine learning (QML) could have the potential to leverage advantages of quantum over classical computing but still lacks strong evidence of actual improvements and scalability, partly due to phenomena such as barren plateaus. In this paper,...
Error Mitigation in Bosonic Systems via Virtual Distillation
Leonardo Finocchiaro, Marco Robbio, Diogo Gomes +5 more·Jul 6, 2026
Virtual distillation is a promising error-mitigation technique that exploits multiple copies of a noisy quantum state to estimate observables as if measured on a purified state. Although originally introduced in the context of bosonic many-body syste...
Quantum orientation, Noether structure, composition of systems and operations
Heinz-Jürgen Schmidt·Jul 6, 2026
In this paper we argue that, in addition to the statistical structure of quantum theory, another structure, referred to here as the ``Noether structure," is necessary to describe the composition of systems and to define completely positive operations...
Photonic Cluster State Generation from a Quantum Dot Emitting in the Telecom C-band
Giora Peniakov, Reza Hekmati, Johannes Michl +9 more·Jul 6, 2026
Photonic cluster states are a key resource for photonic quantum information processing. So far, deterministic generation of these states has been limited to the near-infrared wavelength range. To achieve quantum advantage in communication while maint...
A Unified Electrostatic-to-Spin Framework for Asymmetric Multi-Gate CMOS Quantum Devices
Zeheng Wang, Yan Liu, Yue Hao +1 more·Jul 6, 2026
In advanced complementary metal-oxide-semiconductor (CMOS) quantum chips, compact gate stacks make it difficult to connect lithographic geometry, electrostatic confinement and many-electron spin filling in one transparent model. This connection is ce...
Emergence of the Scrooge Ensemble in the Sachdev-Ye-Kitaev Model
Zeyu Liu, Pengfei Zhang·Jul 6, 2026
The probabilistic nature of quantum measurement provides a direct window into the structure and complexity of many-body wave functions. When only part of a system is measured, the remaining degrees of freedom form an ensemble of post-measurement stat...
No Distributed Quantum Advantage for 3-Coloring Rooted Trees and 2-Coloring Even Cycles
Pierre Fraigniaud, Frédéric Magniez, Isabella Ziccardi·Jul 6, 2026
Significant effort has been devoted over the past decade to understanding whether quantum resources can provide advantages in distributed computing, and in particular whether they can help overcome locality constraints in networks, typically in Linia...
HamQASBench: A Hamiltonian-Informed Diagnostic Benchmark for Evaluating Quantum Architecture Search
Jiayang Niu, Akib Karim, Yan Wang +5 more·Jul 6, 2026
Quantum Architecture Search (QAS) automates the design of parameterized quantum circuits for variational quantum algorithms, yet existing benchmarks organize instances by molecular identity or qubit count -- criteria agnostic to Hamiltonian structure...
