Approaching the scaling limit of transport through lattices with dephasing
Subhajit Sarkar, Gabriela Wójtowicz, Bartłomiej Gardas +2 more·Oct 5, 2025
We examine the stationary--state equations for lattices with generalized Markovian dephasing and relaxation. When the Hamiltonian is quadratic, the single--particle correlation matrix has a closed system of equations even in the presence of these two...
Wormhole-Induced correlation: A Link Between Two Universes
Zhilong Liu, Wentao Liu, Xiaofang Liu +1 more·Oct 5, 2025
Motivated by the profound connection between quantum mechanics and spacetime geometry, particularly the conjectured correspondence between wormholes and quantum entanglement as proposed in the ER=EPR framework, this study investigate the influence of...
Plugging Leaks in Fault-Tolerant Quantum Computation and Verification
Theodoros Kapourniotis, Dominik Leichtle, Luka Music +1 more·Oct 3, 2025
With the advent of quantum cloud computing, the security of delegated quantum computation has become of utmost importance. While multiple statistically secure blind verification schemes in the prepare-and-send model have been proposed, none of them a...
Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers
Lucas Alves Zischler, Çağla Özkan, Tristan Vosshenrich +10 more·Oct 3, 2025
The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most recent proposals leverage novel fibers designed for space-division multipl...
Emulation of Coherent Absorption of Quantum Light in a Programmable Linear Photonic Circuit
Govind Krishna, Jun Gao, Sam O Brien +5 more·Oct 2, 2025
Non-Hermitian quantum systems, governed by nonunitary evolution, offer powerful tools for manipulating quantum states through engineered loss. A prime example is coherent absorption, where quantum states undergo phase-dependent partial or complete ab...
Characterizing Superconducting Qubits using Averaged Circuit Eigenvalue Sampling
Tauno Palomaki, Shu Xin Wu, Noah Huffman +7 more·Oct 2, 2025
Efficient characterization of noise during quantum gate operations is an essential step to building and scaling up a quantum computer. One such protocol is averaged circuit eigenvalue sampling (ACES) which efficiently characterizes a noisy gate set b...
Critical Quantum Sensing: a tutorial on parameter estimation near quantum phase transitions
George Mihailescu, Uesli Alushi, Roberto Di Candia +2 more·Oct 2, 2025
Quantum phenomena offer the possibility of measuring physical quantities with precision beyond classical limits. However, current progress is constrained by scalability, environmental noise, and challenges in practical integration. This highlights th...
HIV-1 protease cleavage sites detection with a Quantum convolutional neural network algorithm
Junggu Choi, Junho Lee, Kyle L. Jung +1 more·Oct 2, 2025
In this study, we propose a quantum convolutional neural network (QCNN)-based framework with the neural quantum embedding (NQE) to predict HIV-1 protease cleavage sites in amino acid sequences from viral and human proteins. To assess the effectivenes...
Digital quantum simulation of many-body localization crossover in a disordered kicked Ising model
Tomoya Hayata, Kazuhiro Seki, Seiji Yunoki·Oct 2, 2025
Simulating nonequilibrium dynamics of quantum many-body systems is one of the most promising applications of quantum computers. However, a faithful digital quantum simulation of the Hamiltonian evolution is very challenging in the present noisy quant...
Background Suppression in Quantum Sensing of Dark Matter via Collective Entangled-State Projection
Shion Chen, Hajime Fukuda, Yutaro Iiyama +5 more·Oct 2, 2025
We show that measuring dark matter signal by projecting quantum sensors in the collective excited state can highly suppress the non-collective noise background, hence improving the sensitivity significantly. We trace the evolution of the sensors' sta...
Extracting the photon indistinguishability error from measurable quantum observables
Franciscus H. B. Somhorst, Jason Saied, Eleanor G. Rieffel +1 more·Oct 2, 2025
We present a method to extract the photon indistinguishability error from Hong-Ou-Mandel interference measurements, accounting for the combined effects of loss and multiphoton noise that contaminate the single-photon Hilbert space. Our analysis resol...
Entanglement distribution via satellite: an evaluation of competing protocols assuming realistic free-space optical channels
Nicholas Zaunders, Timothy C. Ralph·Oct 2, 2025
A key technical requirement of any future quantum network is the ability to distribute quantum-entangled resources between two spatially separated points at a high rate and high fidelity. Entanglement distribution protocols based on satellite platfor...
Limitations of strong coupling in non-Markovian quantum thermometry
Qing-Shou Tan, Yang Liu, Xulin Liu +3 more·Oct 2, 2025
We investigate quantum thermometry using a single-qubit probe embedded in a non-Markovian environment, employing the numerically exact hierarchical equations of motion (HEOM) to overcome the limitations of Born-Markov approximations. Through a system...
A low-circuit-depth quantum computing approach to the nuclear shell model
Chandan Sarma, P. Stevenson·Oct 2, 2025
In this work, we introduce a new qubit mapping strategy for the Variational Quantum Eigensolver (VQE) applied to nuclear shell model calculations, where each Slater Determinant (SD) is mapped to a qubit, rather than assigning qubits to individual sin...
Quantum-inspired Benchmark for Estimating Intrinsic Dimension
Aritra Das, Joseph T. Iosue, Victor V. Albert·Oct 1, 2025
Machine learning models can generalize well on real-world datasets. According to the manifold hypothesis, this is possible because datasets lie on a latent manifold with small intrinsic dimension (ID). There exist many methods for ID estimation (IDE)...
Pre-Distillation of Magic States via Composite Schemes
Muhammad Erew, Moshe Goldstein, Yaron Oz +1 more·Oct 1, 2025
Magic state distillation (MSD) is a cornerstone of fault-tolerant quantum computing, enabling non-Clifford gates via state injection into stabilizer circuits. However, the substantial overhead of current MSD protocols remains a major obstacle to scal...
On the Relativity of Quantumness as Implied by Relativity of Arithmetic and Probability
Marek Czachor·Oct 1, 2025
A hierarchical structure of isomorphic arithmetics is defined by a bijection $g_\mathbb{R}:\mathbb{R}\to \mathbb{R}$. It entails a hierarchy of probabilistic models, with probabilities $p_k=g^k(p)$, where $g$ is the restriction of $g_\mathbb{R}$ to t...

Tatsuya Numajiri, Shion Yamashika, Tomonori Tanizawa +3 more·Oct 1, 2025
Graph states are entangled states that are essential for quantum information processing. As experimental advances enable the realization of large-scale graph states, efficient fidelity estimation methods are crucial for assessing their robustness aga...
Quantum Probabilistic Label Refining: Enhancing Label Quality for Robust Image Classification
Fang Qi, Lu Peng, Zhengming Ding·Oct 1, 2025
Learning with softmax cross-entropy on one-hot labels often leads to overconfident predictions and poor robustness under noise or perturbations. Label smoothing mitigates this by redistributing some confidence uniformly, but treats all samples equall...

Tomohiro Shitara, Gabriel Mintzer, Yuuki Tokunaga +1 more·Oct 1, 2025
Squeezed cat quantum error correction (QEC) codes have garnered attention because of their robustness against photon-loss and excitation errors while maintaining the biased-noise property of cat codes. In this work, we reveal the utility of the unexp...
