A Scalable Decoder Micro-architecture for Fault-Tolerant Quantum Computing

Understand

Quantum computation promises significant computational advantages over classical computation for some problems.

• However, quantum hardware suffers from much higher error rates than in classical hardware.
• As a result, extensive quantum error correction is required to execute a useful quantum algorithm.
• The decoder is a key component of the error correction scheme whose role is to identify errors faster than they accumulate in the quantum computer and that must be implemented with minimum hardware resources in order to scale to the regime of practical applications.
