A Low-Power CMOS Quantum Controller for Transmon Qubits

The development of large-scale quantum computers will require the implementation of scalable control and measurement electronics, which may have to operate at a temperature as low as 4 K. In this paper, we review a first-generation control IC that has been implemented for use with transmon qubits. We first explain the requirements which such an IC must meet and then present the circuit design. We then describe a series of quantum control experiments. The paper concludes with a discussion of future work.
