Compilation-informed probabilistic logical-error cancellation
Giancarlo Camilo, Thiago O. Maciel, Allan Tosta +4 more·Aug 27, 2025
The potential of quantum computers to outperform classical ones in practically useful tasks remains challenging in the near term due to scaling limitations and high error rates of current quantum hardware. While quantum error correction (QEC) offers ...
Resolving Microscopic Correlated Electron Dynamics via 2000-Qubit Quantum Simulation
Jaka Vodeb·Aug 27, 2025
Understanding how quantum materials return to equilibrium after being driven into excited states is a fundamental problem in condensed matter physics. A prototypical material, 1T-TaS$_2$, exhibits complex electronic textures made up of domain walls, ...
A method of an on-demand beamsplitter for trapped-ion quantum computers
Takanori Nishi·Aug 27, 2025
Quantum information processing using local modes of trapped ions has been applied to implementing bosonic quantum error correction codes and conducting efficient quantum simulation of bosonic systems. However, control of entanglement among local mode...
Direct probing of the simulation complexity of open quantum many-body dynamics
Lucia Vilchez-Estevez, Alexander Yosifov, Jinzhao Sun·Aug 27, 2025
Simulating open quantum systems is key to understanding non-equilibrium processes, as persistent influence from the environment induces dissipation and can give rise to steady-state phase transitions. A common strategy is to embed the system-environm...
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...
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...
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...
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...
