A Sejong University research team, in collaboration with German researchers, has determined a crucial threshold for quantum error correction, addressing one of the major obstacles in the field of quantum computing. Led by Professor Kim Se-yong from the Department of Physics and Astronomy, the university's team calculated the fundamental threshold probability for typical errors that arise at the circuit level of quantum computing, alongside researchers from RWTH Aachen University in Germany.
Professor Markus Müller headed the German research group. Their 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 presently concentrating on developing quantum error correction technologies to tackle computational errors stemming from environmental noise.
The joint research team employed the parallel tempering Monte Carlo technique to examine the random coupled-plaquette gauge model statistically.
