Unmanned underwater vehicles (UUVs) play a major role in deep oceanic applications, such as underwater pipeline and cable inspection, underwater terrain mapping, as well as in military applications such as mine detection, harbor monitoring and anti-submarine warfare. These applications mostly take place in deep sea environments and include time consuming, heavy duty tasks that are not suitable to be performed by divers. Some underwater operations (e.g., surveying a large area or an area with a complex seafloor topography) require more than one UUV for efficient task completion. In these cases, the deployment of multiple UUVs in formation can perform such tasks and reduce operational time and expenses.

A requirement for a group of UUVs to move in a controlled formation is an underwater communication link between the UUVs. In addition to UUV operation in formation, underwater communication links can also be used for UUV docking or data transfer from an operating UUV to a data storage platform. The two latter applications allow UUVs to operate with longer periods underwater without the need for excessive emerging/submerging.

To that effect, the invention provides for the design of optical detectors and methods of optical detection for UUVs. The detectors can be used to dynamically position UUVs in both static-dynamic systems (e.g. a fixed light source as a guiding beacon and a UUV) and dynamic-dynamic systems (e.g., a moving light source mounted on the crest of a leader UUV and a follower UUV).

#9,824,065 - Systems and Methods for Chaotic Entanglement Using Cupolets

Kevin M. Short (CEPS – Mathematics); Matthew Morena
Advances in development of quantum computers are being hindered by the difficulty in controlling and managing extremely small-scale quantum effects that are necessary to achieve required data processing capabilities. The chaotic nature of quantum systems creates special challenges from a stability viewpoint. Interacting chaotic systems have bound or entangled states that need to be stabilized without external intervention in order to harness the quantum capabilities for different applications around computing and communications. Cupolets (Chaotic, Unstable, Periodic Orbit-LETS) are a new class of waveforms detected when control of chaotic systems is performed. These cupolets can in turn be used in the generation of other waveforms for various applications such as secure communications, image processing and data compression. This invention has come up with a novel technique to control and stabilize entangled cupolets so they can be used in different quantum computing devices and applications.

This invention is able to impact several areas around quantum computing and information security. In the area of encryption, information that needs to be encrypted is stored in one system but can only be retrieved through a second system, where the two systems are entangled, and the entanglement is broken after the data storage has been completed. Reestablishing entanglement is necessary to recover the data that was encrypted, and this helps increase the security level of the data.
