Demonstrating efficient and scalable integration between a Qblox qubit control system and Deltaflow, a hardware-accelerated QEC system.

Fault-tolerant quantum computing requires that syndrome data is processed faster than the rate at which it is produced, as well as the low latency application of logical qubit corrections. This necessitates an effective integration between the quantum error correction system (QEC system) performing the decoding, and the qubit control system performing readout and real-time feedback. In this talk we will discuss a demonstration of the rotated planar surface code simulated on a Qblox Cluster control system and decoded on Deltaflow, a hardware-accelerated real-time QEC system. The integration is facilitated by QECi, a dedicated Quantum Error Correction interface aimed to support high-throughput and low-latency communication within a fault-tolerant quantum computing system. We will present results on the performance characteristics of the integration, and discuss how the system will scale to larger QEC demonstrations.
