HybridQC: Hardware-Grounded Simulation of Tightly Integrated Hybrid Quantum-Classical Systems
Panayiotis Christou, Shuwen Kan, Ying Mao·Jul 15, 2026
Hybrid quantum-classical application performance is increasingly limited by classical control, host-to-QPU communication, and scheduling rather than quantum execution. Existing simulators and runtime interfaces analyze individual kernels but fail to ...
StreamingQEC: Streaming Quantum Error Correction in Tightly Integrated Quantum-Classical Systems via Certified Recurrence
Panayiotis Christou, Shuwen Kan, Hao Wang +1 more·Jul 15, 2026
Fault-tolerant quantum computing requires a continuous hybrid quantum error correction (QEC) pipeline comprising measurement readout, syndrome transport, decoding, feedback, and control. Existing QEC simulators primarily evaluate circuits, noise mode...
Marker-free deformable registration and fusion for augmented reality-guided positive margin localization during tumor resection surgery
Yue Yang, Annie Benson, Matthieu Chabanas +7 more·Jul 15, 2026
Positive margins in head and neck oncologic surgery require mapping specimen-side pathology findings to the patient resection bed. This is challenging because pathologists identify the positive margin on slices of the resected, deformed specimen, whi...
A versatile laser-machined rf trap for arrays of 100+ ions
Frank G. Schroer, Ilyoung Jung, Thomas W. Burkle +4 more·Jul 15, 2026
Large ion crystals in diverse geometries are a key resource for quantum simulation experiments. In this work, we introduce a macroscopic rf trap that supports a wide variety of one-dimensional ion configurations as well as lateral two-dimensional cry...
A Reality Check on Quantum Optimisation: Evidence from an Industrial Case Study
Hila Safi, Karen Wintersperger, Oliver von Sicard +2 more·Jul 14, 2026
Quantum Processing Units promise speed-ups for selected computational problems, including combinatorial optimisation, but their industrial utility remains an open challenge. We study an industrial variant of the Job-Shop Scheduling Problem using quan...
Precision quantum simulation of magnon spectra and interactions
Trond I. Andersen, Nikita Astrakhantsev, Jeronimo Martinez +329 more·Jul 14, 2026
Quantum simulation promises to advance materials discovery by accurately simulating complex states of matter, their microscopic excitations, and macroscopic response functions. The central challenge in resolving the underlying interacting dynamics is...
A Measurement Plane for Quantum Networking
Abderrahim Amlou, Amar Abane, Anouar Rahmouni +6 more·Jul 14, 2026
Quantum networking testbeds lack a distinct plane for coordinating distributed measurements and collecting experimental data across heterogeneous devices. To address this gap, we present the Measurement Plane, a dedicated plane that complements the d...
Exactly Solvable Diffraction-Grating Scattering Problems for TE and TM waves
Farhang Loran, Ali Mostafazadeh·Jul 14, 2026
In J.~Phys.~A {\bf 31}, 3493 (1998), Berry provides an analytic solution of the problem of determining the diffracted beam intensities for atoms incident upon a grating given by the potential, $v(x,y):=iV_0(e^{i\mathfrak{K}\,y}-1)$ for $0\leq x\leq\e...
Quantum Motion from Local Transition Susceptibility
Jan Klaers·Jul 14, 2026
We characterize quantum motion based on the susceptibility of a quantum state to weak local state conversion. The inverse susceptibility can be interpreted as a passage speed characterizing local motion independently of probability transport. For ind...
Let the Qudit Do the Jacobi: A Structured Quantum Algorithm for Spectral Decomposition
A. Mandilara·Jul 14, 2026
Jacobi diagonalization is a long-established numerical algorithm for the spectral decomposition of Hermitian and, more generally, normal matrices. In this work, we develop a qudit-native quantum realization of the Jacobi diagonalization algorithm for...
Proof in a Bottle: Long-Lived Verifiable Secret Sharing via Pre-Quantum Commitment and Immutable Ledger Binding
Markus Jakobsson, Keir Finlow-Bates·Jul 14, 2026
Traditional secret sharing techniques such as Verifiable Secret sharing (VSS) are vulnerable to quantum attacks by a Cryptographically Relevant Quantum Computer (CRQC) running Shor's algorithm. We observe that the binding a VSS needs is required only...
Comparing the three W-like states with the W state
Dafa Li·Jul 14, 2026
In [Phy. Rev. Lett., 98, 260501 (2007)] and previous papers, the W-like states were used in many quantum communication schemes, distillation, teleportation and superdense coding. So far, no one has compared the W-like states with the W state. We inve...
A Fibre-Integrated SPDC Heralded Single-Photon Source Using Zn-Indiffused PPLN Ridge Waveguides at Telecom Wavelengths
Peter Iveson, Paolo L. Mennea, Goronwy Tawy +7 more·Jul 14, 2026
We report a fibre-integrated heralded single-photon source based on a commercial Zn-indiffused MgO:PPLN ridge waveguide operated in Type-0 degenerate spontaneous parametric down-conversion (SPDC). The device emits a broadband spectrum spanning approx...
An Information-Theoretic Characterization of Optimal Value-Readout in Response-Register Quantum Oracles
Milad Ghadimi, Hesam Soltanpanahi, Vahid Salari·Jul 14, 2026
Response-register quantum oracles admit two complementary operational interpretations: value readout and phase kickback. Although their computational equivalence is well understood, the quantitative relation between these two operational interpretati...
Two-Tower Quantum Matrix Chain Multiplication: Trading Qubits for Depth
Giacomo Antonioli, Anna Bernasconi, Alessandro Berti +2 more·Jul 14, 2026
Matrix chain multiplication -- computing $\mathcal{W} = M^{(0)}\cdots M^{(K-1)}$ where $M^{(k)} \in \mathbb{R}^{P_k \times P_{k+1}}$ -- arises in scientific computing, machine learning, and graph analysis. Despite the importance of this problem, for ...
Robust Nonperturbative Trapped-Ion Quantum Logic
Luca Stefanescu, Florian Mintert·Jul 14, 2026
Entangling gates of trapped ions are typically mediated by collective motional degrees of freedom. Weak coupling between qubit and motional degrees of freedom and the resulting harmonic dynamics give access to a broad range of gate schemes, but also ...
Emulating XX catalysts for quantum annealing via self-consistent transverse fields
Mohammadhossein Dadgar, Christopher L. Baldwin·Jul 14, 2026
Fully-connected transverse interactions have been considered as catalysts for quantum annealing that could mitigate exponentially small gaps and circumvent first-order phase transitions, but their experimental implementation remains challenging. In t...
A robust and modular cesium magneto-optical trap using diverging laser beams
Paola Luna, Kenneth Nakasone, Andrei Zhukov +4 more·Jul 14, 2026
Magneto-optical traps (MOTs) are a workhorse technology for neutral-atom quantum sensing, simulation, and computing. Here, we demonstrate a MOT optimized for inertial quantum sensing and precision metrology applications. Our MOT traps $4\times10^8$ c...
Classical and quantum mechanics across representations: an operational reading of the Wigner Weyl correspondence
Samuel Schlegel, Borivoje Dakić, Flavio Del Santo·Jul 14, 2026
The physical content of a theory is not intrinsically tied to any single mathematical formalism. Both classical and quantum mechanics admit equivalent representations, notably in phase space and in Hilbert space, related by the Wigner-Weyl correspond...
Magic without a phase: phase-independent stabilizer Rényi entropy in gluon scattering
Jinwei Chu, Savan Kharel·Jul 14, 2026
Magic, also known as non-stabilizerness, measures the usefulness of a quantum state for quantum computation. While magic is defined relative to a choice of computational basis, in some physical settings the available data determine this basis only up...
