Latest Patents

One of his latest patents is titled "Method and system for hybrid classical-quantum communication." This invention focuses on a method that involves transmitting a single photon with a specific quantum state over a communication medium using a quantum mode set. Simultaneously, it transmits a classical light beam over the same medium using a classical mode set. The invention highlights the use of non-separable modes, which may include two degrees of freedom of a single photon or classical light, such as spatial modes and polarization.

Another notable patent is the "Optical communication method and system." This invention pertains to methods and systems designed for optical communication. It creates a multiplexed beam from an incident beam, where the multiplexed beam consists of a predetermined number of spatial modes generated and multiplexed together independently of wavelength. The system allows for de-multiplexing downstream in a simultaneous manner, yielding the predetermined number of spatial modes used as channels or bits in encoding schemes.
