Classical Simulations of Low Magic Quantum Dynamics
Kemal Aziz, Haining Pan, M. Gullans +1 more·Aug 27, 2025
We develop classical simulation algorithms for adaptive quantum circuits that produce states with low levels of ``magic''(i.e., non-stabilizerness). These algorithms are particularly well-suited to circuits with high rates of Pauli measurements, such...
Composite-Dimensional Topological Codes with Boundaries and Defects
Mohamad Mousa, Amit Jamadagni, Eugene Dumitrescu·Aug 26, 2025
We introduce new algorithms and provide example constructions of stabilizer models for the gapped boundaries, domain walls, and $0D$ defects of Abelian composite-dimensional twisted quantum doubles. Using the physically intuitive concept of condensat...
Unquestionable Bell theorem for interwoven frustrated down conversion processes
Paweł Cieśliński, Jan-Åke Larsson, Marcin Markiewicz +2 more·Aug 26, 2025
Interwoven frustrated parametric down conversion (PDC) processes produce interference effects based on path identity [Phys. Rev. Lett. 118, 080401 (2017)]. In this letter we show Bell nonclassicality of the processes: a proper violation of the Clause...
Universal Dynamics with Globally Controlled Analog Quantum Simulators
Hong-Ye Hu, Abigail McClain Gomez, Liyuan Chen +6 more·Aug 26, 2025
Analog quantum simulators with global control fields have emerged as powerful platforms for exploring complex quantum phenomena. Despite these advances, a fundamental theoretical question remains unresolved: to what extent can such systems realize un...
Iterative Partition Search Variational Quantum Algorithm for Solving Shortest Vector Problem
Zi-Wen Huang, Xiao-Hui Ni, Jia-Cheng Fan +4 more·Aug 26, 2025
The Partition Search Algorithm (PSA) and Iterative Quantum Optimization with an Adaptive Problem (IQOAP) are leading variational quantum algorithms for solving Shortest Vector Problem (SVP). However, each has limitations that restrict its practical i...
Architecting Distributed Quantum Computers: Design Insights from Resource Estimation
Dmitry Filippov, Peter Yang, Prakash Murali·Aug 26, 2025
In the emerging field of Fault Tolerant Quantum Computation (FTQC), resource estimation is an important tool for quantitatively comparing prospective architectures, identifying hardware bottlenecks and informing which research paths are most valuable...
QAgent: An LLM-based Multi-Agent System for Autonomous OpenQASM programming
Zhenxiao Fu, Fan Chen, Lei Jiang·Aug 26, 2025
Noisy Intermediate-Scale Quantum (NISQ) devices have begun to exhibit early quantum advantages on classically intractable problems, spanning physics simulations to Gaussian boson sampling. Yet, realizing these benefits remains challenging for non-exp...
Full counting statistics and first-passage times in quantum Markovian processes: Ensemble relations, metastability, and fluctuation theorems
Paul Menczel, C. Flindt, F. Brange +2 more·Aug 26, 2025
We develop a comprehensive framework for characterizing fluctuations in quantum transport and nonequilibrium thermodynamics using two complementary approaches: full counting statistics and first-passage times. Focusing on open quantum systems governe...
Efficient and scalable inter-module switching for distributed quantum computing architectures
Kamil Bradler·Aug 26, 2025
Large-scale fault-tolerant quantum computers of the future will likely be modular by necessity or by design. Modularity is inevitable if the substrate cannot support the desired error-correction code due to its planar geometry or manufacturing constr...
Towards Quantum Machine Learning for Malicious Code Analysis
Jesus Lopez, Saeefa Rubaiyet Nowmi, Viviana Cadena +1 more·Aug 26, 2025
Classical machine learning (CML) has been extensively studied for malware classification. With the emergence of quantum computing, quantum machine learning (QML) presents a paradigm-shifting opportunity to improve malware detection, though its applic...
Quantum computing on encrypted data with arbitrary rotation gates
Mohit Joshi, Manoj Kumar Mishra, S. Karthikeyan·Aug 26, 2025
An efficient technique of computing on encrypted data allows a client with limited capability to perform complex operations on a remote fault-tolerant server without leaking anything about the input or output. Quantum computing provides information-t...
First-Quantized Quantum Simulation of Non-Relativistic QED with Emergent Topologically Protected Coulomb Interactions
Torin F. Stetina, Nathan Wiebe·Aug 26, 2025
We provide a simulation algorithm that properly addresses light matter interaction between non-relativistic first-quantized charged particles and quantum electromagnetic fields. Unlike previous work, our Hamiltonian does not include an explicit Coulo...
Enhanced algorithmic perfect state transfer on IBM quantum computers
Zong-Yuan Ge, Lian-Ao Wu, Zhao-Ming Wang·Aug 26, 2025
Perfect state transfer (PST) through a spin chain can be theoretically obtained via predesigned PST couplings. We perform the algorithmic PST simulations through short spin chains on IBM quantum computers, alongside Qiskit simulations. The results de...
Chiral Discrimination on Gate-Based Quantum Computers
Muhammad Arsalan Ali Akbar, Sabre Kais·Aug 25, 2025
We present a novel approach to chiral discrimination using gate-based quantum processors, addressing a key challenge in adapting conventional control techniques using modern quantum computing. Schemes such as stimulated rapid adiabatic passage (STIRA...
Entanglement dynamics of monitored noninteracting fermions on graphics processing units
Bo Fan, Can Yin, Antonio M. García-García·Aug 25, 2025
The description of the entanglement dynamics of monitored noninteracting fermions, including the existence of measurement-induced phase transitions (MIPTs), is a challenging problem with conflicting results in the literature. The mapping of the probl...
