The demonstration of a quantum link between microwave and optical frequencies would be an important step toward the realization network superconducting processors. A major impediment to electro-optic transduction in all platforms explored date is noise added by thermal occupation modes involved process, it has proved difficult realize low occupancy concurrently with other desirable features like high duty cycle efficiency. In this work, we present efficient continuously operating...
The dielectric loss of silicon nitride (${\mathrm{Si}}_{3}{\mathrm{N}}_{4}$) limits the performance microwave-frequency devices that rely on this material for sensing, signal processing, and quantum communication. Using superconducting resonant circuits, we measure cryogenic tangent either as-deposited or high-temperature annealed stoichiometric ${\mathrm{Si}}_{3}{\mathrm{N}}_{4}$ as a function drive strength temperature. internal behavior electrical resonators is largely consistent with...
A transducer capable of faithfully converting single quanta between microwave and optical frequencies would enable an network superconducting quantum computers. primary challenge in the ongoing effort to bridge these frequency scales is detrimental effect that photons have on circuits. This manuscript details membrane-optomechanical Fabry-P´erot architecture we employ a high-efficiency electrooptomechanical transducer. We use chemical bonding process create integrated membrane-mirror etalon...
Entangling superconducting quantum processors via light would enable new means of secure communication and distributed computing. However, transducing signals between these disparate regimes the electromagnetic spectrum remains an outstanding goal, interfacing qubits with electro-optic transducers presents significant challenges due to deleterious effects optical photons on superconductors. Moreover, many remote entanglement protocols require multiple qubit gates both preceding following...
We perform dispersive readout of a superconducting qubit using optical heterodyne detection via mechanical electro-optic transducer, without causing significant backaction on the qubit. This is key milestone in linking remote quantum processors.
The dielectric loss of silicon nitride (Si$_3$N$_4$) limits the performance microwave-frequency devices that rely on this material for sensing, signal processing, and quantum communication. Using superconducting resonant circuits, we measure cryogenic tangent either as-deposited or high-temperature annealed stoichiometric Si$_3$N$_4$ as a function drive strength temperature. internal behavior electrical resonators is largely consistent with standard tunneling model two-level systems (TLS),...
