Real-time decoding of quantum error correction codes using high-performance computing
Lingling Lao, Qiang Wang, Yuanqi Liu +10
Quantum error correction (QEC) is indispensable for building scalable fault-tolerant quantum computers. Effective QEC demands stringent real-time decoding: the decoder must process…
An iterative Ising decoder for quantum error correction codes
Yuanqi Liu, Weilei Zeng, Peixiang Li +6
The Ising framework maps the decoding problem in quantum error correction onto ground-state optimization of a classical Hamiltonian, in which - error correlations enter as cr…
A Concatenated Dual Displacement Code for Continuous-Variable Quantum Error Correction
Fucheng Guo, Frank Mueller, Yuan Liu
The continuous-variable (CV) Gaussian no-go theorem fundamentally limits the suppression of Gaussian displacement errors using only Gaussian gates and states. Prior studies have em…
COMPAS: A Distributed Multi-Party SWAP Test for Parallel Quantum Algorithms
Brayden Goldstein-Gelb, Kun Liu, John M. Martyn +4
The limited number of qubits per chip remains a critical bottleneck in quantum computing, motivating the use of distributed architectures that interconnect multiple quantum process…
General quantum computation on photons assisted with double single-sided cavity system
Jiu-Ming Li, Jun-Yan Liu, Yuan-Yuan Liu +2
We propose a physical system consisting of two optical cavities and a two-level system (TLS), which can be viewed as a double single-sided cavity system. The two cavities are cross…
Unification of Finite Symmetries in Simulation of Many-body Systems on Quantum Computers
Victor M. Bastidas, Nathan Fitzpatrick, K. J. Joven +5
Symmetry is fundamental in the description and simulation of quantum systems. Leveraging symmetries in classical simulations of many-body quantum systems can results in significant…
