Phoniton systems, devices, and methods

摘要

An artificial composite object combines a quantum of sound with a matter excitation. A phonon in a confinement structure containing the matter excites it from an initial state to an excited state corresponding to a frequency of the phonon. Relaxation of the matter back to the initial state emits a phonon of the same frequency into the confinement structure. The phonon confinement structure, for example, a cavity, traps the emitted phonon thereby allowing further excitation of the matter. The coupling between the phonon and the matter results in a quantum quasi-particle referred to as a phoniton. The phoniton can find application in a wide variety of quantum systems such as signal processing and communications devices, imaging and sensing, and information processing.

1. A method for producing a phoniton, the method comprising:
trapping a phonon in a cavity; and coupling the trapped phonon to a quantum two-level system in the cavity, the quantum two-level system having a first energy state and a second energy state, the phonon being coupled such that a mode of the trapped phonon corresponds to a transition at or near a difference between the first and second energy states, the quantum two-level system being arranged at an anti-node or a node of the trapped phonon.
