Abstract

Radio frequency cryogenic switches are a critical enabling technology for quantum information science, both for calibration and high throughput testing of samples. Traditionally solenoid-based switches have been used, but transition is being made to MEMS-based switches due to their lower power dissipation, smaller size, and the tendency of solenoid switches to produce current pulses which destroy expensive cryogenic amplifiers. These MEMS switches require a 90-volt signal to be applied to the control lines which determine the state of the switches. Switches exist which have built in CMOS-based control electronics to drive the 90 V, but these do not work at the cryogenic temperatures used in quantum information science. The instrument presented here is a 19-inch rack-mount controller for a cryogenic MEMS switch network which allows a human operator to see the state of the switch via a row of clearly marked indicator lights, and to change the state manually via buttons on an LED-based indicator board or automatically via Python-based serial port commands. The design can also be modified for to control other switches that require either a large voltage or current to switch.
