This thesis experiences on significant steps in the direction of the belief of scalable quantum networks. It addresses the experimental implementation of a deterministic interplay mechanism among flying optical photons and a unmarried trapped atom. particularly, it demonstrates the nondestructive detection of an optical photon. To this finish, unmarried rubidium atoms are trapped in a three-d optical lattice on the heart of an optical hollow space within the powerful coupling regime. complete regulate over the atomic nation — its place, its movement, and its digital country — is accomplished with laser beams utilized alongside the resonator and from the aspect. while faint laser pulses are mirrored from the resonator, the mixed atom-photon kingdom acquires a state-dependent part shift. In a primary sequence of experiments, this can be hired to nondestructively realize optical photons through measuring the atomic kingdom after the mirrored image procedure. Then, quantum bits are encoded within the polarization of the laser pulse and within the Zeeman kingdom of the atom. The state-dependent part shift mediates a deterministic common quantum gate among the atom and one or successively mirrored photons, that's used to generate entangled atom-photon, atom-photon-photon, and photon-photon states out of separable enter states.
