Quantum-classical crossover in fault-tolerant quantum dynamics simulation
Jinzhao Sun, Bozhen Zhou, Jue Xu +28
While quantum computers promise to solve classically intractable problems, identifying the point at which fault-tolerant quantum computation outperforms the best classical algorith…
Entanglement-facilitated macroscopic cluster formation in quantum many-body dynamics
Xiao Wang, Alexander Yosifov, Aditya Iyer +1
The study examines how correlated (entangled) initial states in a 2D quantum Ising model change false‑vacuum decay, promoting the growth of large connected clusters instead of many…
Trotter error compensation with polylogarithmic precision and nested-commutator scaling without ancillas
Xinzhao Wang, Shuo Zhou, Ziruo Wang +5
The paper introduces a high‑order nested‑commutator compensation (HNCC) algorithm that reduces the circuit size needed for Hamiltonian simulation to polylogarithmic dependence on p…
Gauge Symmetry in Quantum Simulation
Masanori Hanada, Shunji Matsuura, Andreas Schafer +1
Quantum simulation of non-Abelian gauge theories requires careful handling of gauge redundancy. We address this challenge by presenting universal principles for treating gauge symm…
Extensible universal photonic quantum computing with nonlinearity
Shang Yu, Jinzhao Sun, Kuan-Cheng Chen +17
Universal quantum computing requires an architecture that supports both linear circuits and, crucially, strong nonlinear resources. For quantum photonic systems, integrating such n…
High-precision and low-depth quantum algorithm design for eigenstate problems
Jinzhao Sun, Pei Zeng, Tom Gur +1
Estimating the eigenstate properties of quantum systems is a long-standing, challenging problem for both classical and quantum computing. Existing universal quantum algorithms typi…
