Abstract: A technique relates to a superconducting quantum device. A fixed frequency transmon qubit (110A) is provided. A tunable frequency transmon qubit (110B) is provided. The fixed frequency transmon qubit (110A) is coupled to the tunable frequency transmon qubit (110B) to form a single qubit (100).

Abstract: A technique relates to frequency conversion. A mechanical resonator is configured to oscillate at a mechanical resonance frequency with a displacement in an axis. An optical resonator includes a first mirror opposite a second mirror in which an optical cavity is formed between. The first mirror is fixed to the mechanical resonator such that the first mirror is moved to change an optical length of the optical cavity according to the displacement of the mechanical resonator. Changing the optical length changes an optical resonance frequency of the optical resonator. A microwave resonator is positioned to move according to the displacement of the mechanical resonator such that moving the mechanical resonator changes a Josephson inductance of the microwave resonator, thereby changing a microwave resonance frequency of the microwave resonator.
