A Sejong University research team, in collaboration with German researchers from RWTH Aachen University, has pinpointed a critical threshold for quantum error correction, a significant hurdle in the field of quantum computing. Led by professor Kim Se-yong of the Department of Physics and Astronomy, the university's research team determined a fundamental probability threshold for prevalent errors that arise at the circuit level during quantum computing operations.
Working alongside professor Markus Müller's team from Germany, the findings were published last month in npj Quantum Information under the title "The random coupled-plaquette gauge model and the surface code under circuit-level noise." Quantum computing experts worldwide are currently concentrating on devising quantum error correction technologies to mitigate computational errors caused by external environmental noise.
Employing the parallel tempering Monte Carlo technique, the joint research team analyzed the random coupled-plaquette gauge model in statistical simulations.
