Benchmarking Quantum Software Testing with Scalable Quantum Programs
Yuechen Li, Minqi Shao, Xiyuan Li +2 more·Jul 2, 2026
Quantum software testing (QST) checks whether quantum programs behave according to their intended specifications. A key requirement for QST research is a benchmark that supports rigorous empirical evaluation on programs that are testable and better r...
Mid-infrared pure-state quantum light source based on lithium niobate waveguides
Huang Yuhang, Wang Dongzhou, Ke Shaolin +1 more·Jul 2, 2026
Mid-infrared quantum light sources hold broad application prospects in fields such as gas sensing and infrared thermal imaging. However, currently used mid-infrared quantum entangled light sources primarily rely on bulk periodically poled lithium nio...
Local distinguishability of six bipartite orthogonal product states
Guang-Bao Xu, Hua-Kun Wang, Yu-Guang Yang +1 more·Jul 2, 2026
It is necessary to investigate the local distinguishability of orthogonal quantum state sets, as their adoption in protocol design helps diminish quantum state transmission and cut operational costs. In this paper, we explore the local distinguishabi...
Quantum sensing of aging transitions
Huining Zhang, Yunbo Zhang, Xiaoguang Wang +1 more·Jul 2, 2026
The aging transition is a critical phenomenon in which collective dynamics deteriorate as the fraction of inactive quantum nodes exceeds a threshold, referred to as the aging transition point. Such transitions are relevant to a broad range of biologi...
Compressive Spectrum Sensing via Spectral Multiplexing in Rydberg Atomic Receiver
Jun-Rong Chen, Yi-Ming Yin, Le-Bin Chen +7 more·Jul 2, 2026
Rydberg-atomic receivers exhibit exceptional sensitivity yet are fundamentally constrained by the narrow instantaneous bandwidth, limiting their practical deployment in broadband scenarios. Prior approaches typically expand the bandwidth by physicall...
Partially-Blind Single-Qubit Classification over a Prototype Hybrid Quantum Network
Matteo Pasini, Tzula Benjamin Propp, Janice van Dam +4 more·Jul 2, 2026
In the NISQ era, there is a need for resource-efficient proof-of-principle experiments that can be built up to genuine utility. Single-qubit classifiers (SQCs) are small-scale hybrid quantum-classical machines capable of performing a basic machine le...
False vacuum decay in a two-dimensional quantum spin system
Luka Pavešić, Ian G. Moss, Simone Montangero·Jul 2, 2026
False vacuum decay describes the relaxation of a metastable state through the nucleation and growth of bubbles of the stable phase. Despite describing a broad variety of phenomena across different fields, the quantum version of the nucleation theory ...
Insecurity of Measurement-Device-Independent Quantum Key Distribution
Konstantin Zaitsev, Polina Acheva·Jul 2, 2026
The security of practical quantum key distribution (QKD) systems is fundamentally constrained by vulnerabilities of single-photon detectors. Measurement-device-independent quantum key distribution (MDI-QKD) was proposed to remove this limitation by a...
Towards a Phonology-Informed Evaluation of Multilingual TTS
Sneha Ray Barman, Neeraj Kumar Sharma, Shakuntala Mahanta·Jul 2, 2026
Neural TTS systems can sound natural across languages, but naturalness does not guarantee the preservation of sound contrasts that distinguish words from their grammatical forms. Standard metrics like MOS do not test for this. We propose a classifier...
Hybrid quantum-classical neural network for sentiment analysis
Giacomo Cappiello, Filippo Caruso, Xing Liang +1 more·Jul 2, 2026
Quantum machine learning has recently emerged as a promising paradigm that leverages the expressive power of quantum circuits to address complex learning tasks. In this work, we investigate the applicability of hybrid quantum-classical neural network...
Tuning quantum magic of pure quantum chaotic states with a gravity dual
Antonio M. García-García, Xianlong Liu, Jie-ping Zheng·Jul 2, 2026
Quantum magic is a fundamental resource that quantifies to what extent quantum states can be efficiently simulated on a classical computer. We study it for states constructed from the Sachdev-Ye-Kitaev (SYK) Hamiltonian with $N$ Majoranas by the ferm...
Growth of Schrödinger cats in particle-number measurement schemes
S. B. Korolev, A. A. Silin, A. A. Poshevkina +1 more·Jul 2, 2026
In this work, we investigate the generation of squeezed Schrödinger cat states in schemes based on photon-number-resolving measurements on multimode Gaussian states. We derive analytical expressions for the states generated in two- and three-mode sch...
LUCI on IBM Hardware: Error Suppression with Almost Half Syndrome Density
Younghun Kim, Spiro Gicev, Martin Sevior +1 more·Jul 2, 2026
Long-lived logical qubits are essential for fault-tolerant quantum computation. However, the practical performance of traditional error correction protocols relies on performing specific syndrome circuits, causing vulnerability to hardware defects an...
Lubkin-Page typicality bounds for Type~II von~Neumann factors
Zhi-Wei Wang, Samuel L. Braunstein·Jul 2, 2026
Typicality arguments for emergent spacetime rely on the Lubkin-Page bounds, which show that generic quantum states have vanishing correlations between subsystems. These bounds assume a tensor-product Hilbert space (a Type~I von~Neumann algebra), but ...
Low-ancilla block encodings via Hamiltonian simulation
Yuxin Zhang, Changpeng Shao·Jul 2, 2026
Block encodings are a central primitive in quantum algorithms, but standard constructions typically require logarithmic ancilla overhead and complicated controlled operations. Recent lower bounds further show that such ancilla overhead is unavoidable...
Memory Device for Photons by exploiting Brillouin Interactions in Nanowires
Hashem Zoubi·Jul 2, 2026
Memory devices for single photons are notable components for quantum information processing and quantum communications. The present study investigates the possibility of achieving storage of light at the level of single photons inside nanofibers by e...
Extracting Work from Discrete Quantum Polytropic Processes
Vishal Anand, Swarup Kumar Giri, Avijit Misra +2 more·Jul 2, 2026
We establish an upper bound on extractable work for time-dependent, non-Markovian quantum heat engines operating with finite baths. This bound analytically isolates the distinct thermodynamic penalties arising from system-bath correlations, bath non-...
Interferometric characterization of the relative phase between two X-ray free-electron laser pulses using long-lived Mössbauer resonances
Lukas Wolff, Jörg Evers·Jul 2, 2026
Coherence-based spectroscopy methods are powerful tools to explore structure and dynamics of matter. However, towards higher photon energies, the generation of sequences of pulses with well-characterized relative delays and phases remains a challenge...
Structure-Aware Compilation for Scalable Neutral-Atom Quantum Computing
Dekuan Dong, Fengyu Zou, Hengzhun Chen +2 more·Jul 2, 2026
We study the compilation of structured quantum gate families on two-dimensional neutral-atom arrays, aiming to reduce addressing and transport overhead under realistic hardware constraints. For single-qubit gates, we exploit the algebraic structures ...
Performance of a two-mode coherent superposed channel in continuous-variable quantum teleportation
Deepak, Arpita Chatterjee·Jul 2, 2026
Glauber's coherent state is denoted by $\ketα$ and its two-mode extension is represented by $\ket{α,β}$. In this work, we introduce a two-mode superposition operator $A=tab+ra^\dagger b^\dagger$, whose action on the two-mode coherent state produces t...
