TANNER CROWDER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Low brightness, entanglement-based, semi-passive private communication protocol
    Patent number: 10924191
    Abstract: A communications apparatus includes an entangled-photon generator for generating entangled pairs of photons including a plurality of idler photons and a corresponding plurality of signal photons. The communications apparatus includes a quantum memory for storing the plurality of idler photons. The communications apparatus includes a transmitter for transmitting the plurality of signal photons. The communications apparatus includes an optical element for selectively reflecting the plurality of signal photons to encode a reflected signal. The communications apparatus includes a receiver for detecting a plurality of incoming photons. The communications apparatus includes a correlator configured to determine the reflected signal from the plurality of incoming photons. The correlator determines an entanglement correlation between the plurality of incoming photons with the plurality of idler photons.
