Xanadu and AMD Launch Open-Source Backline Extension for PennyLane
Xanadu and AMD have released Backline, an open-source extension for PennyLane designed to link quantum processors to classical compute resources including CPUs, GPUs, FPGAs, and SmartNICs. The framework provides Python-native, microsecond-scale communication aimed at removing the data bottleneck between classical and quantum systems for workloads such as quantum error correction.
Backline could make real-time quantum error correction experiments practical on near-term quantum processors by supplying microsecond-latency feedback between quantum hardware and classical decoders.
