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…
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…
Simple and high-precision Hamiltonian simulation by compensating Trotter error with linear combination of unitary operations
Pei Zeng, Jinzhao Sun, Liang Jiang +1
Trotter and linear-combination-of-unitary (LCU) are two popular Hamiltonian simulation methods. We propose Hamiltonian simulation algorithms using LCU to compensate Trotter error,…
Quantum subspace verification for error correction codes
Junjie Chen, Pei Zeng, Qi Zhao +2
Benchmarking the performance of quantum error correction codes in physical systems is crucial for achieving fault-tolerant quantum computing. Current methodologies, such as (shadow…
