Structural encoding with classical codes for computational-basis bit-flip correction in the early fault-tolerant regime
IlKwon Sohn, Changyeol Lee, Wooyeong Song +2
Achieving reliable performance on early fault-tolerant quantum hardware will depend on protocols that manage noise without incurring prohibitive overhead. We propose a novel framew…
