Abstract
A method of exchanging quantum information between a photon and a micro/nano scale resonant structure is provided. The method comprises providing the resonant structure (15) in an optical waveguide (10). The method further comprises passing a photon (18) through the resonant structure in the optical waveguide. The method also comprises applying a driving signal (17) to the resonant structure to cause phonic oscillation of the resonant structure and to modulate a wavelength of the photon such that the passing the photon through the resonant structure results in an exchange of quantum information between the photon and a quantum state in a phonon of the resonant structure.

A method of exchanging quantum information between a photon and a micro/nano scale resonant structure, the method comprising:
- providing the resonant structure in an optical waveguide;
- passing a photon through the resonant structure in the optical waveguide;
- and
- applying a driving signal to the resonant structure to cause phonic oscillation of the resonant structure and to modulate a wavelength of the photon such that the passing the photon through the resonant structure results in an exchange of quantum information between the photon and a quantum state in a phonon of the resonant structure.
A system comprising:
- an optical waveguide;
- a micro/nano scale resonant structure within the optical waveguide;
- and
- a driving system configured to apply a driving signal to the resonant structure and cause phonic oscillation of the resonant structure and thus modulate a wavelength of a photon passing through the resonant structure and hence exchange quantum information between the photon and a quantum state in a phonon of the resonant structure.
A method of entangling two photons, the method comprising:
- providing a first micro/nano scale resonant structure in a first optical waveguide;
- providing a second micro/nano scale resonant structure in a second optical waveguide;
- entangling the first and second resonant structures;
- passing a first photon through the first resonant structure of the first optical waveguide;
- and
- passing a second photon through the second resonant structure of the second optical waveguide.
A system comprising:
- a first optical waveguide;
- a second optical waveguide;
- a first micro/nano scale resonant structure in the first optical waveguide;
- a second micro/nano scale resonant structure in the second optical waveguide;
- and
- a driving system configured to apply an incident signal to the first resonant structure and the second resonant structure and hence excite and entangle the first and second resonant structures.
