Power and limitations of distributed quantum state purification
Benchi Zhao, Yu-Ao Chen, Xuanqiang Zhao +3 more·Sep 10, 2025
Quantum state purification protocols, which mitigate noise by converting multiple copies of noisy quantum states into fewer copies with a lower noise level, have applications in quantum communication and computation with imperfect devices. Here, we s...
Simulating magic state cultivation with few Clifford terms
Kwok Ho Wan, Zhenghao Zhong, Ainhoa Zapirain·Sep 10, 2025
Building upon [arXiv:2509.01224], we present a few methods on how to simulate the non-Clifford $d=5$ magic state cultivation circuits [arXiv:2409.17595] with a sum of $\approx 8$ Clifford ZX-diagrams on average, at $0.1\%$ noise. Compared to a magic ...
Loss-tolerant parallelized Bell-state generation with a hybrid cat qudit
Z. M. McIntyre, W. A. Coish·Sep 10, 2025
Having multiple Bell pairs shared by distant quantum registers provides a key resource for both quantum networks and distributed quantum computing. In this paper, we present a protocol for parallelized Bell-pair generation that uses the phase of a co...
Benchmarking Optimization Algorithms for Automated Calibration of Quantum Devices
Kevin Pack, Shai Machnes, Frank K. Wilhelm·Sep 10, 2025
We present the results of a comprehensive study of optimization algorithms for the calibration of quantum devices. As part of our ongoing efforts to automate bring-up, tune-up, and system identification procedures, we investigate a broad range of opt...
Robustness of quantum algorithms: Worst-case fidelity bounds and implications for design
Julian Berberich, Tobias Fellner, Robert L. Kosut +1 more·Sep 10, 2025
Errors occurring on noisy hardware pose a key challenge to reliable quantum computing. Existing techniques such as error correction, mitigation, or suppression typically separate the error handling from the algorithm analysis and design. In this pape...
Addressing requirements for crosstalk-free quantum-gate operation in many-body nanofiber cavity QED systems
Tim Keller, Seigo Kikura, Rui Asaoka +3 more·Sep 10, 2025
A distributed network architecture in which flying photons connect individual modules containing stationary atomic qubits is a promising approach for scaling up neutral-atom based quantum-computing platforms. We consider an all-fiber based platform c...
Towards solving industrial integer linear programs with Decoded Quantum Interferometry
Francesc Sabater, Ouns El Harzli, Geert-Jan Besjes +6 more·Sep 10, 2025
Optimization via decoded quantum interferometry (DQI) has recently gained a great deal of attention as a promising avenue for solving optimization problems using quantum computers. In this paper, we apply DQI to an industrial optimization problem in ...
The Born rule as a natural transformation of functors
Boyu Yang, James Fullwood·Sep 10, 2025
In this work, we show that the quantum mechanical notions of density operator, positive operator-valued measure (POVM), and the Born rule, are all simultaneously encoded in the categorical notion of a natural transformation of functors. In particular...
Comparing quantum incompatibility of device sets from an operational perspective
Kensei Torii, Ryo Takakura, Ryotaro Imamura·Sep 10, 2025
To effectively utilize quantum incompatibility as a resource in quantum information processing, it is crucial to evaluate how incompatible a set of devices is. In this study, we propose an ordering to compare incompatibility and reveal its various pr...
Enhancing Sum Capacity via Quantum and No-Signaling Cooperation Between Transmitters
Seung-Hyun Nam, Hyun-Young Park, Jiyoung Yun +3 more·Sep 10, 2025
We consider a communication scenario over a discrete memoryless interference channel or multiple access channel without feedback, where transmitters exploit classical, quantum, or no-signaling cooperation. In this scenario, several previous works hav...
Tripartite Correlation Signal from Multipartite Entanglement of Purification
Ning Bao, Keiichiro Furuya, Joydeep Naskar·Sep 10, 2025
We propose a signal $Δ^{(3)}_p$ for genuine tripartite entanglement in finite-dimensional quantum systems and $Δ^{(3)}_w$ for holographic systems. We prove that $Δ^{(3)}_p$ is non-negative for any tripartite entangled mixed states. Based on the conje...
Quantum Fisher information matrix via its classical counterpart from random measurements
Jianfeng Lu, Kecen Sha·Sep 10, 2025
Preconditioning with the quantum Fisher information matrix (QFIM) is a popular approach in quantum variational algorithms. Yet the QFIM is costly to obtain directly, usually requiring more state preparation than its classical counterpart: the classic...
Estimation of deuteron binding energy with renormalization group-based effective interactions using the variational quantum eigensolver
Sreelekshmi Pillai, S. Ramanan, V. Balakrishnan +1 more·Sep 10, 2025
We have obtained the binding energy of the deuteron on a quantum simulator using the variational quantum eigensolver for renormalization group (RG)-based low-momentum effective interactions. The binding energy (BE) has been calculated in the truncate...

Quantum Error Correction in Adversarial Regimes
Rahul Arvind, Nikhil Bansal, Dax Enshan Koh +2 more·Sep 10, 2025
In adversarial settings, where attackers can deliberately and strategically corrupt quantum data, standard quantum error correction reaches its limits. It can only correct up to half the code distance and must output a unique answer. Quantum list dec...
