Latest Patents
One of Duncan'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 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 properties of the quantum light or cavity, effectively trapping the quantum light. Subsequent application of this mechanism switches properties to release the quantum light from the optical cavity. Additionally, it offers quasi-deterministic single-photon generation through temporal multiplexing of a photon pair source integrated within the cavity.
Another notable patent is "Ultrafast temporal filtering for quantum communications." This method involves preparing photons encoded in a single spatial, spectral, and temporal (SST) mode to form a quantum signal at the sender's end. 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. The system performs active temporal filtering by switching the polarization of the quantum signal without substantially adding noise, minimizing saturation of the detector.
