Controlling transmon qubits with a low-power cryogenic CMOS AWG

View publication

Abstract

Next generation quantum computers will undergo a paradigm shift whereupon multi qubit devices will predominantly perform circuits that support quantum error correction. This new era of quantum computing will require orders of magnitude more qubits than are currently being produced today, and at that scale cryogenic control electronics are considered a key technology in order to facilitate high performance operations. Here we present results demonstrating coherent control of transmon qubits using a low-power general-purpose CMOS RF AWG in 14nm FinFET technology, that is thermally anchored to the 4K stage of a dilution refrigerator. We evaluate the impact of control noise on qubit performance, and draw comparisons between the cryogenic CMOS RF AWG and standard RF room control electronics.
