Experimental Quantum Channel Purification
Yue-Yang Fei, Zhenhuan Liu, Rui Zhang +7 more·Oct 31, 2025
Quantum networks, which integrate multiple quantum computers and the channels connecting them, are crucial for distributed quantum information processing but remain inherently susceptible to channel noise. Channel purification emerges as a promising ...
Quantum Secret Sharing Scheme on Hypercyclic Quantum Structures
Lei Li, Zhi Li·Oct 31, 2025
This paper investigates the construction of efficient quantum secret sharing schemes for quantum access structures based on hypergraphs with three hyperedges. We prove that hypercycles with three hyperedges are quantum access structures if and only i...
Dependence-Driven, Scalable Quantum Circuit Mapping with Affine Abstractions
Marouane Benbetka, Merwan Bekkar, Riyadh Baghdadi +1 more·Oct 31, 2025
Qubit Mapping is a critical task in Quantum Compilation, as modern Quantum Processing Units (QPUs) are constrained to nearest-neighbor interactions defined by a qubit coupling graph. This compiler pass repairs the connectivity of two-qubit gates whos...
FlowQ-Net: A Generative Framework for Automated Quantum Circuit Design
Jun Dai, Michael Rizvi-Martel, Guillaume Rabusseau·Oct 30, 2025
Designing efficient quantum circuits is a central bottleneck to exploring the potential of quantum computing, particularly for noisy intermediate-scale quantum (NISQ) devices, where circuit efficiency and resilience to errors are paramount. The searc...
Stesso: A reconfigurable decomposition of $n$-bit Toffoli gates using symmetrical logical structures and adjustable support qubits
Shanyan Chen, Ali Al-Bayaty, Xiaoyu Song +1 more·Oct 30, 2025
An $(n+1)$-bit Toffoli gate is mainly utilized to construct other quantum gates and operators, such as Fredkin gates, arithmetical adders, and logical comparators, where $n \geq 2$. Several researchers introduced different methods to decompose $(n+1)...
A Zero Added Loss Multiplexing (ZALM) Source Simulation
Jerry Horgan, Alexander Nico-Katz, Shelbi L. Jenkins +6 more·Oct 29, 2025
Zero Added Loss Multiplexing (ZALM) offers broadband, per channel heralded EPR pairs, with a rich parameter space that allows its performance to be tailored for specific applications. We present a modular ZALM simulator that demonstrates how design c...
Overcoming disorder in superconducting globally driven quantum computing
Riccardo Aiudi, Julien Despres, Roberto Menta +5 more·Oct 29, 2025
We study the impact of static disorder on a globally-controlled superconducting quantum computing architecture based on a quasi-two-dimensional ladder geometry [R. Menta et al., Phys. Rev. Research 7, L012065 (2025)]. Specifically, we examine how fab...
GHZ-Preserving Gates and Optimized Distillation Circuits
Mingyuan Wang, Guus Avis, Stefan Krastanov·Oct 29, 2025
Greenberger-Horne-Zeilinger (GHZ) states play a central role in quantum computing and communication protocols, as a typical multipartite entanglement resource. This work introduces an efficient enumeration and simulation method for circuits that pres...
Heuristic Quantum Advantage with Peaked Circuits
Hrant Gharibyan, Mohammed Zuhair Mullath, Nicholas E. Sherman +3 more·Oct 29, 2025
We design and demonstrate heuristic quantum advantage with peaked circuits (HQAP circuits) on Quantinuum's System Model H2 quantum processor. Through extensive experimentation with state-of-the-art classical simulation strategies, we identify a clear...
Transition-Aware Decomposition of Single-Qudit Gates
Denis A. Drozhzhin, Evgeniy O. Kiktenko, Aleksey K. Fedorov +1 more·Oct 29, 2025
Quantum computation with $d$-level quantum systems, also known as qudits, benefits from the possibility to use a richer computational space compared to qubits. However, for an arbitrary qudit-based hardware platform, the issue is that a generic qudit...
Detuning Choice for solving MIS and MWIS
Sem Saada Khelkhal, Louis Barcikowsky·Oct 29, 2025
We address the realization of Maximum Weighted Independent Set (MWIS) and quantum Maximum Independent Set (MIS) problems under Pasqal's neutral-atom QPU constraints: limited qubit number, bounds on Ω and Δ, sequence duration, confinement space, minim...
Efficient magic state cultivation with lattice surgery
Yutaka Hirano, Riki Toshio, Tomohiro Itogawa +1 more·Oct 28, 2025
Magic state distillation plays a crucial role in fault-tolerant quantum computation and represents a major bottleneck. In contrast to traditional logical-level distillation, physical-level distillation offers significant overhead reduction by enablin...
Tight Generalization Bound for Supervised Quantum Machine Learning
Xin Wang, Rebing Wu·Oct 28, 2025
We derive a tight generalization bound for quantum machine learning that is applicable to a wide range of supervised tasks, data, and models. Our bound is both efficiently computable and free of big-O notation. Furthermore, we point out that previous...
Optimizing Quantum Compilation via High-Level Quantum Instructions
Evandro C. R. Rosa, Jerusa Marchi, Eduardo I. Duzzioni +1 more·Oct 28, 2025
Current quantum programming is dominated by low-level, circuit-centric approaches that limit the potential for compiler optimization. This work presents how a high-level programming construct provides compilers with the semantic information needed fo...
Quantum evolution with classical fields
