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.
Claims8
A device comprising:
- a phononic crystal, the phononic crystal including:
- a phononic crystal waveguide, the phononic crystal waveguide adapted to carry a phononic signal;
- a signal I/O port, the signal I/O port located at a first end of the phononic crystal waveguide, the signal I/O port adapted to couple the phononic signal into and out of the phononic memory cell for a read or a write process;
- a phononic mirror, the phononic mirror located at a second end of the phononic crystal waveguide opposite the first end of the phononic crystal waveguide, the phononic mirror adapted to reflect the phononic signal;
- a phononic phase shifter, the phononic phase shifter located adjacent the phononic crystal waveguide, the phononic phase shifter adapted to induce a phase shift in the phononic signal;
- and
- a phononic nanocavity, the phononic nanocavity located adjacent the phononic crystal waveguide, the phononic nanocavity adapted to at least one of transfer, store, or exchange phonons with the phononic crystal waveguide.
