Xanadu and AMD have launched Backline, an open-source framework integrated into Xanadu's PennyLane platform, to connect quantum and classical hardware. It provides ultra-low-latency links across CPUs, GPUs, FPGAs, and SmartNICs, resolving the classical-quantum data bottleneck for applications like quantum error correction. Backline enables Python-native, microsecond-scale communication, allowing standard processors to handle real-time quantum feedback loops and offering a hardware-agnostic architecture for hybrid quantum applications.
