Memory-assisted decoder for approximate Gottesman-Kitaev-Preskill codes
Kwok Ho Wan, Alex Neville, Steve Kolthammer · Physical Review Research · 2020
The authors propose an explicit decoder for the approximate Gottesman-Kitaev-Preskill code. The scheme is formulated for multiple rounds of displacement error followed by syndrome extraction measurements and its error estimation is enhanced by considering all recorded syndromes.
