The design is meant to supply all the room temperature control electronics to control the qubits in a superconducting based quantum computer. It is called QubiC and includes FPGAs, Analog to Digital Converters (ADC), Digital to Analog Converters (DAC) and other logic to generate the necessary control pulse to operate a superconducting qubit as well as perform the readout measurement to determine a qubit’s state. The design is customizable and modular and can be adapted to different user’s configurations. Although there are many commercial companies offering control electronic systems for controlling qubits, none of them are open sourced. AQT is hoping that an open-sourced design can be leveraged by the broader quantum information science community to access and improve the design in a way that is similar to what occurs frequently with open-sourced software. Additional information about this design can be found in a blog posted on Phys.org here, a more detailed technical paper posted on IEEE Xplore here, and the open-sourced design files posted on GitHub here.
