International Classification:

H04B 10/02

US Classification:

398173, 398140, 398175

Abstract:

A distributed quantum relay architecture is disclosed. In one embodiment of this architecture, time and wavelength division multiplexing are used to enable a laser pump pulse, already used to create an initial entangled photon pair, to be distributed to a remote relay site, on the same optical fiber as a photon from that initial pair. At that remote site, the pump pulse is amplified and used to locally create the second entangled photon pair that is required for quantum teleportation. This embodiment enables the placement of quantum repeater stations at remote locations without complicated dedicated channels to distribute the pump or electronics. In addition, as lasers are generally among the most expensive components, a significant cost savings is gained, in this embodiment, by using only one pump laser instead of two (or more) as in previous quantum teleportation efforts.

US Classification:

250214R, 359107

Abstract:

A system and method is provided for a source for a heralded single photon comprising a correlated photon-pair generator that provides bursts of multiple photon pairs that may be odd or even in number of pairs, one of each pair having a first but not a second characteristic and the other of each pair having the second but not the first characteristic; a first optical path for photons of pairs having the first characteristic; a second optical path for photons of pairs having the second characteristic; a two-photon absorber in the first optical path that, for each burst of photons, reduces the number of first characteristic photons in the first path to zero or one, depending on whether the number of photon pairs in the burst is even or odd; a photon detector in the second path having a heralding signal output to indicate when the number of photons in the burst is odd; and an optical switch coupled to the output of the second optical path and connected to operate in response to the heralding signal.

International Classification:

H01J 25/50
G21G 4/00

US Classification:

315 3951, 2504931

Abstract:

A photon source capable of emitting, for example, a single photon or a single pair of photons on demand. The photon source may include an excitation region where a single instance of a quantum system is excited using excitation energy. A Stimulated Raman Adiabatic Passage (STIRAP) technique can be used for exciting the quantum system to a desired energy level. The photon source may include a photon emission region physically displaced from the excitation region. A transport device can be used for controllably moving an excited quantum system from the excitation region to the photon emission region. The photon emission region may include a resonant cavity tuned to the de-excitation frequency of the quantum system for inducing de-excitation of the quantum system and emission of a photon. The photon emission resonant cavity may be switchably coupled to an output port by a tunable resonant cavity coupling device.

International Classification:

Abstract:

A nonlinear fiber interferometer is disclosed suitable for fiber sensor and other applications. A first nonlinear fiber section amplifies probe and conjugate sidebands of a pump through four-wave mixing. A second section introduces a phase shift to be measured, for example from a sensor. A third nonlinear fiber section amplifies with phase-sensitive gain to increase signal-to-noise ratio. Based on phase-sensitive output power of probe and/or conjugate components, the phase shift can be measured. Superior performance can be obtained by balancing gain between the (first and third) nonlinear sections. Non-fiber, for example photonic integrated circuit, embodiments are disclosed. Differential sensing, alternative detection schemes, sensing applications, associated methods, and other variations are disclosed.
