Quantum Support Vector Regression for Robust Anomaly Detection
Kilian Tscharke, Maximilian Wendlinger, Sebastian Issel +1 more·May 2, 2025
Anomaly Detection (AD) is critical in data analysis, particularly within the domain of IT security. In this study, we explore the potential of Quantum Machine Learning for application to AD with special focus on the robustness to noise and adversaria...
Distributed Quantum Circuit Cutting for Hybrid Quantum-Classical High-Performance Computing
Mar Tejedor, Berta Casas, Javier Conejero +2 more·May 2, 2025
Most quantum computers today are constrained by hardware limitations, particularly the number of available qubits, causing significant challenges for executing large-scale quantum algorithms. Circuit cutting has emerged as a key technique to overcome...
Engineering CSS surgery: compiling any CNOT in any code
Cl'ement Poirson, Joschka Roffe, R. Booth·May 2, 2025
We introduce a framework for implementing logic in CSS quantum error correction codes, building on the surgery methods of Cowtan and Burton [CB24]. Our approach offers a systematic methodology for designing and analysing surgery protocols. At the phy...
Qracle: A Graph-Neural-Network-Based Parameter Initializer for Variational Quantum Eigensolvers
Chi Zhang, Lei Jiang, Fangjing Chen·May 2, 2025
Variational Quantum Eigensolvers (VQEs) are a leading class of noisy intermediate-scale quantum (NISQ) algorithms with broad applications in quantum physics and quantum chemistry. However, as system size increases, VQE optimization is increasingly hi...
Divide-and-Conquer Simulation of Open Quantum Systems
Thiago Melo D. Azevedo, C. Almeida, Pedro Linck +2 more·May 2, 2025
One of the promises of quantum computing is to simulate physical systems efficiently. However, the simulation of open quantum systems - where interactions with the environment play a crucial role - remains challenging for quantum computing, as it is ...
Hardware-Efficient Universal Linear Transformations for Optical Modes in the Synthetic Time Dimension
Jasvith Raj Basani, Chaohan Cui, Jack Postlewaite +2 more·May 1, 2025
Recent progress in photonic information processing has spurred strong demand in scalable and reconfigurable photonic circuitry. Conventional spatially-meshed multi-port interferometers require a number of components growing quadratically with the sys...
Theory of quasiparticle generation by microwave drives in superconducting qubits
Shoumik Chowdhury, Max Hays, Shantanu R. Jha +4 more·May 1, 2025
Microwave drives play a central role in the control of superconducting quantum circuits, enabling qubit gates, readout, and parametric interactions. As the drive frequencies are typically an order of magnitude smaller than (twice) the superconducting...
Offset Charge Dependence of Measurement-Induced Transitions in Transmons
Mathieu Féchant, Marie Frédérique Dumas, Denis Bénâtre +9 more·May 1, 2025
A key challenge in achieving scalable fault tolerance in superconducting quantum processors is readout fidelity, which lags behind one- and two-qubit gate fidelity. A major limitation in improving qubit readout is measurement-induced transitions, als...
Probing excited-state dynamics of transmon ionization
Zihao Wang, Benjamin D'Anjou, Philippe Gigon +2 more·May 1, 2025
The fidelity and quantum nondemolition character of the dispersive readout in circuit QED are limited by unwanted transitions to highly excited states at specific photon numbers in the readout resonator. This observation can be explained by multiphot...
Improved Fermionic Scattering for the NISQ Era
Michael Hite·May 1, 2025
In the era of noisy intermediate scale quantum (NISQ) hardware, digital quantum computers are limited to shallow circuits on the order of a thousand layers due to system noise and qubit decoherence. Thus, every step of a simulation must be as efficie...
Relativistic orbital-free kinetic energy density functional for one-particle nuclear systems
X. H. Wu, Z. X. Ren, H. Z. Liang +1 more·May 1, 2025
This letter aims to derive the exact relativistic orbital-free kinetic energy density functional for one-particle nuclear systems in one-dimensional case. The kinetic energy is expressed as a functional of both vector and scalar densities. The functi...
Exact treatment of the memory kernel under time-dependent system-environment coupling via a train of delta distributions
Yuta Uenaga, Kensuke Gallock-Yoshimura, Takano Taira·May 1, 2025
Memory effects in a quantum system coupled to an environment are one of the central features in the theory of open quantum systems. The dynamics of such quantum systems are typically governed by an equation of motion with a time-convolution integral ...
On the Schrödingerization method for linear non-unitary dynamics with optimal dependence on matrix queries
Shi Jin, Nana Liu, Chuwen Ma +2 more·May 1, 2025
The Schrödingerization method converts linear partial and ordinary differential equations with non-unitary dynamics into systems of Schrödinger-type equations with unitary evolution. It does so via the so-called warped phase transformation that maps ...
Experimental evidence for the physical delocalization of individual photons in an interferometer
Ryuya Fukuda, Masataka Iinuma, Yuto Matsumoto +1 more·May 1, 2025
It is generally assumed that the detection of a single photon as part of an interference pattern erases all possible which-path information. However, recent insights suggest that weak interactions can provide non-trivial experimental evidence for the...

Reuben Demirdjian, Thomas Hogancamp, Daniel Gunlycke·May 1, 2025
Herein, we present a polylogarithmic decomposition method to load the matrix from the linearized 1-dimensional Burgers' equation onto a quantum computer. First, we use the Carleman linearization method to map the nonlinear Burgers' equation into an i...
A new approximate Eastin-Knill theorem
