Circuit-level benchmarks of GKP-concatenated qLDPC Codes
Yuan Yao, Ruipeng Xing, Jianshuo Gao +1
Scalable fault-tolerant quantum error correction based on Gottesman-Kitaev-Preskill (GKP) codes requires finite-rate outer codes that can exploit analog GKP information under reali…
Low-cost algorithm-to-execution framework for surface-code quantum computing
Yunxin Tang, Zixuan Huo, Junxiang Huang +14
Fault-tolerant quantum computing is progressing from demonstrations of individual logical components toward the execution of useful quantum algorithms on large-scale error-correcte…
Symmetry-Enforced Topological Structures in Quantum Phase Diagrams
Linhao Li, Yuan Yao
We study the topological structure of the quantum phase diagram of gapped systems by identifying the noncontractibility of loops, so-called -families, within the gapped phase…
Gaplessness indicator by topologically trivial twisting operators
Yuan Yao, Linhao Li, Feng-Feng Song
We propose several general necessary conditions for quantum many-body system in one dimension respecting U(1) symmetry to be gapped. We show that the ground-state expectation value…
Twisting-operator approach to identifying gaplessness in SU() fermionic systems
Hao Cheng, Hang Su, Yuan Yao
We propose a general necessary condition for a spinful fermion chain with SU(2) spin-rotation symmetry to be gapped. Specifically, we prove that the expectation value of a properly…
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…
A Three-Layer Architecture for Fault-Tolerant Quantum Computing
Zhirao Wang, Zhou You, Yiming Huang +4
Fault tolerance is an indispensable prerequisite for constructing large-scale universal quantum computers. Drawing philosophies from classical computer architecture, this paper pre…
A Variational Dissipative Framework for Quantum Algorithms
Yuan Yao, Ruipeng Xing, Yongjian Gu +2
Dissipation engineering has attracted growing interest as an approach to controlling open quantum systems through engineered system-environment interactions. Standard variational q…
A Review of Variational Quantum Algorithms: Insights into Fault-Tolerant Quantum Computing
Zhirao Wang, Junxiang Huang, Runyu Ye +8
Variational quantum algorithms (VQAs) have established themselves as a central computational paradigm in the Noisy Intermediate-Scale Quantum (NISQ) era. By coupling parameterized…
Mixed-State Topological Phase: Quantized Topological Order Parameter and Lieb-Schultz-Mattis Theorem
Linhao Li, Yuan Yao
We investigate the extension of pure-state symmetry protected topological phases to mixed-state regime with a strong U(1) and a weak symmetries in one-dimensional sp…
