Xanadu and AMD speed up quantum computing with Backline link
Xanadu and AMD have introduced Backline, an open-platform interface intended to move data between quantum processors and classical CPUs, GPUs, and FPGAs with latency measured in microseconds. The design is presented as a way to support tighter coupling of quantum and classical compute for hybrid workloads.

Within two years, Backline could allow Xanadu's photonic processors to use AMD FPGAs for low-latency feedforward operations, such as conditional state preparation or correction based on measurement outcomes, without a host-PC round trip.
Microsecond-scale latency is comparable to the timescales needed for classical feedforward in photonic measurement-based quantum computing, and AMD already ships FPGA and adaptive SoC lines that can be co-located with quantum control electronics. The main remaining gap is integration engineering rather than new physics.
