Cutting stabiliser decompositions of magic state cultivation with ZX-calculus
Kwok Ho Wan, Zhenghao Zhong·Sep 1, 2025
We apply the cutting stabiliser decomposition techniques [arXiv:2403.10964] to the quantum states generated from magic state cultivation [arXiv:2409.17595], post-selected upon all $+1$ measured values for simplicity. The resultant states to the $d=3$...
Electron transfer between surface-acoustic-wave-induced moving and static quantum dots
M. Olano, G. Giedke·Sep 1, 2025
Fast long-range interactions between distant quantum dots in arrays remains an unsolved issue, which can be key to solve scalability issues in quantum simulation and computation processes, particularly related to the overhead associated with quantum ...
Enhanced measurements on quantum computers via the simultaneous probing of non-commuting Pauli operators
R. P. Simon, Zheng Shi, C. Nation +2 more·Sep 1, 2025
Measuring the state of quantum computers is a highly non-trivial task, with implications for virtually all quantum algorithms. We propose a novel scheme where identical copies of a quantum state are measured jointly so that all Pauli operators within...
Quantum Brush: A quantum computing-based tool for digital painting
Joao S. Ferreira, Arianna Crippa, Astryd Park +5 more·Sep 1, 2025
We present Quantum Brush, an open-source digital painting tool that harnesses quantum computing to generate novel artistic expressions. The tool includes four different brushes that translate strokes into unique quantum algorithms, each highlighting ...
The Chaotic Art: Quantum Representation and Manipulation of Color
Guosheng Hu·Sep 1, 2025
Due to its unique computing principles, quantum computing technology will profoundly change the spectacle of color art. Focusing on experimental exploration of color qubit representation, color channel processing, and color image generation via quant...
Are Enterprises Ready for Quantum-Safe Cybersecurity?
Tran Duc Le, Phuc Hao Do, T. Dinh +1 more·Sep 1, 2025
Quantum computing threatens to undermine classical cryptography by breaking widely deployed encryption and signature schemes. This paper examines enterprise readiness for quantum-safe cybersecurity through three perspectives: (i) the technologist vie...
Sampling Continuous Quantum Dynamics from a Single Static State
S. Gemsheim, Felix Fritzsch·Sep 1, 2025
While quantum simulation is one of the most promising applications of modern quantum devices, accessible simulation times are fundamentally limited by finite coherence times due to omnipresent noise. Based on the ideas of relational dynamics/time and...
Measuring Less to Learn More: Quadratic Speedup in learning Nonlinear Properties of Quantum Density Matrices
Yukun Zhang, Yusen Wu, You Zhou +1 more·Sep 1, 2025
A fundamental task in quantum information science is to measure nonlinear functionals of quantum states, such as $\mathrm{Tr}(\rho^k O)$. Intuitively, one expects that computing a $k$-th order quantity generally requires $O(k)$ copies of the state $\...
Phase-Sensitive Measurements on a Fermi-Hubbard Quantum Processor
Alberto R. Cavallar, Luis Escalera-Moreno, Titus Franz +4 more·Sep 1, 2025
Fermionic quantum processors are a promising platform for quantum simulation of correlated fermionic matter. In this work, we study a hardware-efficient protocol for measuring complex expectation values of the time-evolution operator, commonly referr...
In Silico Benchmarking of Detectable Byzantine Agreement in Noisy Quantum Networks
Mayank Bhatia, Shaan Doshi, Daniel Winton +3 more·Sep 1, 2025
Quantum communication resources offer significant advantages for fault-tolerant distributed protocols, particularly in Byzantine Agreement (BA), where reliability against adversarial interference is essential. Quantum Detectable Byzantine Agreement (...
Do quantum linear solvers offer advantage for networks-based system of linear equations?
Disha Shetty, Supriyo Dutta, Palak Chawla +5 more·Aug 31, 2025
In this exploratory numerical study, we assess the suitability of Quantum Linear Solvers(QLSs)toward providing a quantum advantage for Networks-based Linear System Problems (NLSPs). NLSPs naturally arise from graphs, and are of importance as they are...
Emergence of non-Markovian Decoherent Histories in Integrable Environment: A "Tape Recorder" Model for Local Quantum Observables
Nataliya Arefyeva, Evgeny Polyakov·Aug 31, 2025
We propose a new approach to coarse-grained description of quantum evolution that provides an explicit recipe to construct and evaluate multi-time decoherent histories in a controlled way, applicable to non-Markovian and integrable systems. Specifica...
Self-Organising Memristive Networks as Physical Learning Systems
Francesco Caravelli, Gianluca Milano, Adam Z. Stieg +3 more·Aug 31, 2025
Learning with physical systems is an emerging paradigm that seeks to harness the intrinsic nonlinear dynamics of physical substrates for learning. The impetus for a paradigm shift in how hardware is used for computational intelligence stems largely f...
Implementing Pearl's $\mathcal{DO}$-Calculus on Quantum Circuits: A Simpson-Type Case Study on NISQ Hardware
Pilsung Kang·Aug 31, 2025
Distinguishing correlation from causation is a central challenge in machine intelligence, and Pearl's $\mathcal{DO}$-calculus provides a rigorous symbolic framework for reasoning about interventions. A complementary question is whether such intervent...
Classical algorithms for measurement-adaptive Gaussian circuits
Changhun Oh, Youngrong Lim·Aug 31, 2025
Gaussian building blocks are essential for photonic quantum information processing, and universality can be practically achieved by equipping Gaussian circuits with adaptive measurement and feedforward. The number of adaptive steps then provides a na...
