Xanadu and AMD Launch Backline With a 2.3-Microsecond FPGA-to-CPU Round Trip, Measured Without a Quantum Processor
Xanadu researchers timed round trips of 16-byte messages between an AMD FPGA board and an AMD Threadripper CPU at a median 2.305 microseconds, first as a plain echo and then with a small lookup-table decoder. No quantum processor was attached.
