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...
Through simultaneous but unequal electromechanical amplification and cooling processes, we create a method for nearly noiseless pulsed measurement of mechanical motion. We use transient (TEA) to monitor single motional quadrature with total added noise −8.5±2.0 dB relative the zero-point motion oscillator, or equivalently quantum limit both quadratures. demonstrate that TEA can be used resolve fine structure in phase space oscillator by tomographically reconstructing density matrix squeezed...
Quantum processors based on linear arrays of trapped ions have achieved exceptional performance, but scaling to large qubit numbers requires realizing two-dimensional ion as envisioned in the quantum charge-coupled device (QCCD) architecture. Here, we present a scalable method for control crystals grid-based surface-electrode Paul trap and characterize it context transport operations that sort reorder multispecies crystals. By combining cowiring electrodes at translationally symmetric...
We present a scalable method for the control of ion crystals in grid-based surface electrode Paul trap and characterize it context transport operations that sort reorder multispecies crystals. By combining co-wiring electrodes at translationally symmetric locations each grid site with site-wise ability to exchange voltages applied two special gated by binary input, site-dependent are achieved using only fixed number analog voltage signals single digital input per site. In separate...
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.
