Enhancing Optical Imaging via Quantum Computation
Aleksandr Mokeev, Babak Saif, Mikhail D. Lukin +1 more·Sep 11, 2025
Extracting information from weak optical signals is a critical challenge across a broad range of technologies. Conventional imaging techniques, constrained to integrating over detected signals and classical post-processing, are limited in signal-to-n...
Attributed-graphs kernel implementation using local detuning of neutral-atoms Rydberg Hamiltonian
Mehdi Djellabi, Matthias Hecker, Shaheen Acheche·Sep 11, 2025
We extend the quantum-feature kernel framework, which relies on measurements of graph-dependent observables, along three directions. First, leveraging neutral-atom quantum processing units (QPUs), we introduce a scheme that incorporates attributed gr...
Ergotropic advantage in a measurement-fueled quantum heat engine
Sidhant Jakhar, Ramandeep S. Johal·Sep 11, 2025
This paper investigates a coupled two-qubits heat engine fueled by generalized measurements of the spin components and using a single heat reservoir as sink. Our model extends the proposal of Yi and coworkers [Phys. Rev. E {\bf 96}, 022108 (2017)] wh...
Thermodynamic coprocessor for linear operations with input-size-independent calculation time based on open quantum system
I. V. Vovchenko, A. A. Zyablovsky, A. A. Pukhov +1 more·Sep 11, 2025
Linear operations, e.g., vector-matrix and vector-vector multiplications, are core operations of modern neural networks. To diminish computational time, these operations are implemented by parallel computations using different coprocessors. In this w...
Diabatic quantum annealing for training energy-based generative models
Gilhan Kim, Ju-Yeon Gyhm, Daniel K. Park·Sep 11, 2025
Energy-based generative models, such as restricted Boltzmann machines (RBMs), require unbiased Boltzmann samples for effective training. Classical Markov chain Monte Carlo methods, however, converge slowly and yield correlated samples, making large-s...
Speeding up Pontus-Mpemba effects via dynamical phase transitions
Andrea Nava, Reinhold Egger, Bidyut Dey +1 more·Sep 11, 2025
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up toward a predesignated target state is tied to the existence of a long...
Building globally controlled quantum processors with ZZ interactions
Roberto Menta, Francesco Cioni, Riccardo Aiudi +3 more·Sep 11, 2025
We present a comprehensive framework for constructing various architectures of globally driven quantum computers, with a focus on superconducting qubits. Our approach leverages static inhomogeneities in the Rabi frequencies of qubits controlled by a ...
Expanding the Class of Free Fermions via Twin-Collapse Methods
Jannis Ruh, Samuel J. Elman·Sep 11, 2025
We present a novel graph-theoretic approach to simplifying generic many-body Hamiltonians. Our primary result introduces a recursive twin-collapse algorithm, leveraging the identification and elimination of symmetric vertex pairs (twins), as well as ...
Programmable 200 GOPS Hopfield-inspired photonic Ising machine
Nayem Al-Kayed, Charles St-Arnault, H. Morison +5 more·Sep 11, 2025
Ising machines offer a compelling approach to addressing NP-hard problems1, but physical realizations that are simultaneously scalable, reconfigurable, fast and stable remain elusive. Quantum annealers, such as D-Wave’s cryogenic hardware, target com...
Evaluating Quantum Amplitude Estimation for Pricing Multi-Asset Basket Options
Muhammad Kashif, Shaf Khalid, Nouhaila Innan +2 more·Sep 11, 2025
Accurate and efficient pricing of multi-asset basket options poses a significant challenge, especially when dealing with complex realworld data. In this work, we investigate the role of quantum-enhanced uncertainty modeling in financial pricing optio...
Fault-tolerant transformations of spacetime codes
A. Pesah, Austin K. Daniel, I. Tzitrin +1 more·Sep 11, 2025
Recent advances in quantum error-correction (QEC) have shown that it is often beneficial to understand fault-tolerance as a dynamical process, a circuit with redundant measurements that help correct errors, rather than as a static code equipped with ...
Toward Quantum Enabled Solutions for Real-Time Currency Arbitrage in Financial Markets
Suman Kumar Roy, Rahul Rana, M. G. Chandra +2 more·Sep 11, 2025
Currency arbitrage leverages price discrepancies in currency exchange rates across different currency pairs to gain risk-free profits. It involves multiple trading, where short-lived price discrepancies require real-time, high-speed processing of vas...
Resource quantification for programming low-depth quantum circuits
Entong He, Yuxiang Yang·Sep 11, 2025
Noisy intermediate-scale quantum (NISQ) devices pave the way to implement quantum algorithms that exhibit supremacy over their classical counterparts. Due to the intrinsic noise and decoherence in the physical system, NISQ computations are naturally ...
Quantum-Enhanced Forecasting for Deep Reinforcement Learning in Algorithmic Trading
Jun-Hao Chen, Yu-Chien Huang, Yun-Cheng Tsai +1 more·Sep 11, 2025
The convergence of quantum-inspired neural networks and deep reinforcement learning offers a promising avenue for financial trading. We implemented a trading agent for USD/TWD by integrating Quantum Long Short-Term Memory (QLSTM) for short-term trend...
A hybrid quantum walk model unifying discrete and continuous quantum walks
Tianen Chen, Y. Shang·Sep 11, 2025
Quantum walks, both discrete and continuous, serve as fundamental tools in quantum information processing with diverse applications. This work introduces a hybrid quantum walk model that integrates the coin mechanism of discrete walks with the Hamilt...

Alexandru Cojocaru, Juan A. Garay, Qipeng Liu +1 more·Sep 11, 2025
We give novel lifting theorems for security games in the quantum random oracle model (QROM) in Noisy Intermediate-Scale Quantum (NISQ) settings such as the hybrid query model, the noisy oracle and the bounded-depth models. We provide, for the first t...
Exponential Lindbladian fast forwarding and exponential amplification of certain Gibbs state properties
Zhong-Xia Shang, Dong An, Changpeng Shao·Sep 11, 2025
We investigate Lindbladian fast-forwarding and its applications to estimating Gibbs state properties. Fast-forwarding refers to the ability to simulate a system of time $t$ using significantly fewer than $t$ queries or circuit depth. While various Ha...
