Low-cost algorithm-to-execution framework for surface-code quantum computing
Yunxin Tang, Zixuan Huo, Junxiang Huang +12
The execution of useful quantum algorithms on fault-tolerant processors requires more than a mapping from logical gates to encoded operations: the spatial organization, non-Cliffor…
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…
Accelerating Fault-Tolerant Quantum Computation with Good qLDPC Codes
Guo Zhang, Yuanye Zhu, Ying Li
We propose a fault-tolerant quantum computation scheme that is broadly applicable to quantum low-density parity-check (qLDPC) codes. The scheme achieves constant qubit overhead and…
Planar fault-tolerant logical measurements with low qubit overhead
Yingli Yang, Guo Zhang, Ying Li
Fault-tolerant quantum computation critically depends on architectures uniting high encoding rates with physical implementability. Quantum low-density parity-check (qLDPC) codes, i…
Constant-Overhead Magic State Injection into qLDPC Codes with Error Independence Guarantees
Guo Zhang, Yuanye Zhu, Xiao Yuan +1
Magic states are essential yet resource-intensive components for realizing universal fault-tolerant quantum computation. Preparing magic states within emerging quantum low-density…
