“…1. The exponential dependence of L t on d implies that it is advantageous to work at small separations (nano-slots) in order to increase the sensitivity of the splitting ratio to small deformations and to reduce the device footprint [24]. Full switching is only possible if light transfers at least once from one waveguide to the next i.e.…”

The merger between integrated photonics and quantum optics promises new opportunities within photonic quantum technology with the very significant progress on excellent photon-emitter interfaces and advanced optical circuits. A key missing functionality is rapid circuitry reconfigurability that ultimately does not introduce loss or emitter decoherence, and operating at a speed matching the photon generation and quantum memory storage time of the on-chip quantum emitter. This ambitious goal requires entirely new active quantum-photonic devices by extending the traditional approaches to reconfigurability. Here, by merging nano-optomechanics and deterministic photonemitter interfaces we demonstrate on-chip single-photon routing with low loss, small device footprint, and an intrinsic time response approaching the spin coherence time of solid-state quantum emitters. The device is an essential building block for constructing advanced quantum photonic architectures on-chip, towards, e.g., coherent multi-photon sources, deterministic photon-photon quantum gates, quantum repeater nodes, or scalable quantum networks. * These authors contributed equally to this work.

“…There are many physical mechanisms that mediate the exchange of microwave and optical photons [11]. Among these, as in the classical case, mechanically mediated conversion offers strong coupling rates and low energy consumption [5,12,13]. * wentao@stanford.edu † safavi@stanford.edu Electro-optomechanical conversion using MHz-frequency mechanical membranes [14,15] to mediate interactions between a Fabry-Pérot cavity and a superconducting microwave resonator has been demonstrated with 47% efficiency and 38 added noise photons [16].…”

Efficient interconversion of both classical and quantum information between microwave and optical frequency is an important engineering challenge. The optomechanical approach with gigahertzfrequency mechanical devices has the potential to be extremely efficient due to the large optomechanical response of common materials, and the ability to localize mechanical energy into a micron-scale volume. However, existing demonstrations suffer from some combination of low optical quality factor, low electrical-to-mechanical transduction efficiency, and low optomechanical interaction rate.Here we demonstrate an on-chip piezo-optomechanical transducer that systematically addresses all these challenges to achieve nearly three orders of magnitude improvement in conversion efficiency over previous work. Our modulator demonstrates acousto-optic modulation with Vπ = 0.02 V. We show bidirectional conversion efficiency of 10 −5 with 3.3 µW red-detuned optical pump, and 5.5% with 323 µW blue-detuned pump. Further study of quantum transduction at millikelvin temperatures is required to understand how the efficiency and added noise are affected by reduced mechanical dissipation, thermal conductivity, and thermal capacity. arXiv:1909.04627v1 [quant-ph]

“…The quantum entanglement between microwaves, light and microwave could be distributed to other network nodes through the entanglement swapping protocol [22][23][24][25]. In addition, this quadripartite system can be fabricated on chips [26][27][28], which proposes a new approach to realize the integrated microwave source for quantum illumination radar systems. This paper is organized as follows.…”

We in theory proposed a hybrid system consisting of a mechanical resonator, an optical Fabry-Perot cavity and two superconducting microwave circuits to generate stationary continuous-variable quantum entanglement between two microwave modes. We show that the hybrid system can also achieve quantum entanglement of other bipartite subsystems in experimentally accessible parameter regimes, which has the potential to be useful in quantum information processing and quantum illumination radar.
