20090188788 | Method for Chlorinating Water by Electrolysis and/or Light Projection for Pool Operating with Mechanical Energy of the Delivery Nozzle - The invention concerns a system for chlorinating water by electrolysis and/or light projection for pool operating with mechanical energy of the delivery nozzle. The invention concerns a system for chlorinating water by electrolysis and illumination of pools provided with a water circulating system. The system is easily set on the entire pool without affecting its sealed character and uses a free and safe source of energy, the motive power of the water from the delivery nozzle, the device consisting of a hollow single-unit assembly ( | 07-30-2009 |

20150077734 | BIPHOTON RANGING WITH HOM INTERFERENCE - A method for range finding of a target including: generating a first photon and a second photon identical to the first photon; transmitting the first photon towards the target and delaying the second photon by a time delay; receiving the first photon reflected from the target and the delayed second photon; interacting the reflected first photon and the delayed second photon to produce HOM interference; detecting photo-statistics at an output of the HOM interference; when the two photons are output at the same output port, repeating the above processes; when the reflected first single photon and the delayed second single photon are output at different output ports, changing the time delay and repeating the above processes; repeating the above processes for a number of times to arrive at a final estimate for a value of the time delay corresponding to the final estimate of the target range. | 03-19-2015 |

20110280405 | SYSTEMS AND METHODS FOR STABILIZATION OF INTERFEROMETERS FOR QUANTUM KEY DISTRIBUTION - Systems and methods are described in which both a quantum key distribution (QKD) transmitter and QKD receiver may keep both of their two-path interferometers stable, with regard to path length drift, relative to an internal reference laser are described. Systems and methods are also proposed whereby the transmitter interferometer may have only a single path (e.g., Sagnac interferometers). The systems and methods described herein may greatly improve the performance of quantum cryptographic transceivers that may make use of these systems and methods. | 11-17-2011 |
20120076503 | SYSTEMS AND METHODS FOR QUANTUM ILLUMINATION DETECTION FOR OPTICAL COMMUNICATIONS AND TARGET DETECTION - A detection system including a receiver, a transmitter, and a processor for stealthy target detection or optical communications is described. Optical communications may be spread spectrum encoded communications over a bright background communication channel. The transmitter includes a quantum frequency entanglement source for outputting a signal beam and an idler beam, and transmission optics for directing the signal beam towards a remote surface. Photons in the idler beam are quantum-mechanically entangled in frequency with photons the signal beam. The transmitter includes a first spectrometer for measuring a frequency band associated with photons in the idler beam. The receiver includes a second spectrometer for identifying the frequency band associated with the photons in the received return beam. The system includes a processor configured to process the output of the spectrometers to determine the presence of a target in a target region or a message encoded in the received return beam. | 03-29-2012 |
