Real-time Quantum Error Correction for a Surface-Code Logical Qubit
ORAL
Abstract
Achieving fault-tolerant universal quantum computation hinges on performing multi-round quantum error correction in real time. Several technical challenges, from instruction bandwidth to timing considerations, make it challenging to engineer a control system capable of real-time error correction. We present a control architecture for surface code with a tightly-coupled real-time quantum error decoder. We demonstrate real-time decoding of error syndromes for a Surface-17 logical qubit satisfying experimental timing constraints. We present the realization of multiple error decoding strategies and compare the hardware resources required for each implementation.
