Title: Innovations of J Howell Mitchell, Jr.
Introduction
J Howell Mitchell, Jr. is a notable inventor based in Amherst, NH (US). He has made significant contributions to the field of quantum key distribution (QKD) with a total of six patents to his name. His work focuses on enhancing the security and efficiency of communication systems through innovative methods.
Latest Patents
One of his latest patents is a QKD system with synchronization channel verification. This invention discloses systems and methods for verifying error-free transmission of the synchronization channel in a QKD system. The method involves sending a first pseudo-random bit stream (PRBS) over the sync channel from Alice to Bob, and verifying the accurate transmission of this stream at Bob. Additionally, it includes sending a second PRBS from Bob to Alice, with verification at Alice. If certain bits in both PRBSs are error-free, the sync channel is verified, allowing the QKD system to commence operation.
Another significant patent is related to multiplexing QKD channels. This invention outlines systems and methods for multiplexing two or more channels of a QKD system. The method includes putting the optical public channel signal in return-to-zero format in a transmitter at one QKD station and amplifying this signal just before detection at the other station. This approach allows for a lower power public channel signal, making it more suitable for multiplexing with other QKD signals.
