Latest Patents

One of Sussman's latest patents is titled "Fibre optic integrated quantum memory for light." This invention provides an efficient quantum memory for storing a quantum state of light, such as a photon, for a temporary period of time in a fibre-integrated optical cavity. It allows for the recall of the quantum state of light and quantum information at a later time with a high probability of success. The invention employs a nonlinear optical switching mechanism to modify at least one property of the quantum light or cavity, effectively trapping the quantum light in the optical cavity. Subsequent application of the nonlinear optical switching mechanism switches at least one property of the stored quantum light or cavity to release the quantum light from the optical cavity. Additionally, this patent offers quasi-deterministic single-photon generation by temporal multiplexing of a photon pair source integrated within the cavity.

Another significant patent by Sussman is "Ultrafast temporal filtering for quantum communications." This quantum communication method involves preparing photons encoded in a single spatial, spectral, and temporal (SST) mode to form a quantum signal at a sender. The quantum signal is then introduced into a quantum channel. At the receiver's end, a detector and filtering system optically process the quantum signal, rejecting background noise photons in the quantum channel. The method also includes active temporal filtering by switching the polarization of the quantum signal without substantially adding noise, minimizing saturation of the detector.
