RSFQ is regarded as a well-developed technique for communications between classic parts and quantum parts of superconducting quantum computer.
Accordingly, all controls and data-exchanges with classically operated electronics can be brought by high-speed on chip RSFQ circuitry.
Besides, external communications between RSFQ and semiconductors at room temperature can be realized by using optical fiber channels combined with MSM ( metal-semiconductor-metal ) switches and laser-emitting diodes.
