| DWPI Title: Reconfigurable phononic device e.g. scalable and microfabricated quantum transducer device for providing quantum transduction between microwave quantum information systems and flying optical photon qubit in optical fiber at telecommunications band wavelengths, has shifter coupled to splitter output |
| Abstract: Various reconfigurable phononic devices, including phase shifters, mirrors, Mach Zehnder interferometers, memories, and transducers for use in both classical and quantum computing systems are disclosed. The individual phononic devices may be combined in various configurations to implement desired, more complex functionality. The phononic devices may be coupled together to implement the desired functionality using phononic waveguides. The phononic devices include one or more phase shifters that are operationally based on either hyperelasticity or a moving boundary effect. |
| Use: Reconfigurable phononic device e.g. scalable and microfabricated quantum transducer device for providing quantum transduction between microwave quantum information systems and flying optical photon qubits in optical fibers at telecommunications band wavelengths for use in classical and quantum processing systems. |
| Advantage: The device provides optimal memory functionality for microwave-based quantum information systems to function in sophisticated transparent optical networks when switching protocols are used to maximize utilization of quantum network resources and realizes use of established and efficient techniques for creating itinerant non-Gaussian microwave fields using microwave qubits with the ability to measure properties of the itinerant photon field in the optical domain after the microwave-to-optical transduction. The device provides improved operation performance, increases piezoelectric transducer efficiency of transduction and decreases piezoelectric transducer bandwidth. |
| Novelty: The device has a first phononic phase shifter coupled to a first phononic beam splitter output to receive first phononic beam splitter output signal. The first phononic phase shifter provides first phase shift in the first phononic beam splitter output signal to couple phase shifted first phononic beam splitter output signal to a first phononic phase shifter output. A second phononic phase shifter is coupled to a second phononic beam splitter output to receive second phononic beam splitter output signal, where the second phononic phase shifter induces second phase shift in the second phononic beam splitter output signal to couple phase shifted second phononic beam splitter output signal to a second phononic phase shifter output. An input end of a phononic beam combiner is coupled to the second phononic phase shifter output to couple a portion of the second phase shifted second phononic beam splitter output signal to the first phononic beam combiner output. |
