- Quantum error correction is vital for quantum computers to achieve their full potential and avoid exponential slowdowns.
- The study demonstrates low-latency feedback using a scalable FPGA decoder integrated into a superconducting quantum processor's control system.
- An 8-qubit stability experiment with up to 25 decoding rounds showed a sub-microsecond mean decoding time per round, indicating the backlog problem can be avoided.
- Logical error suppression was observed as the number of decoding rounds increased, enhancing error correction effectiveness.
- A fast-feedback experiment achieved a decoding response time of 9.6 μs for 9 measurement rounds, highlighting real-time decoding capabilities.
