Title: Hiroo Kunimori: Innovator in Quantum Cryptography
Introduction
Hiroo Kunimori is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of quantum cryptography, holding a total of 2 patents. His work focuses on enhancing secure communication methods through innovative technologies.
Latest Patents
Kunimori's latest patents include an "Apparatus and method for quantum cryptography communication." This invention describes a quantum cryptography communication apparatus that facilitates secure communication between a transmitter and a receiver. The apparatus features a first communicating unit that transmits and receives a communication signal using relatively strong pulse light, and a second communicating unit that handles a relatively weak quantum cryptography signal during periods when the communication signal is off. This design allows for the adjustment of the receiver's attitude axis to align with that of the transmitter.
Another notable patent is the "Coherent optical receiver." This device incorporates a 90-degree optical hybrid circuit for inputting received signal light. It includes I-channel and Q-channel photo detectors, a clock extraction circuit for synchronizing the clock with the demodulated signal, and sampling circuits for processing the signal outputs. The digital signal processing section converts the sampled signals into a digital format and outputs them, while also compensating for light dispersion and phase fluctuations.
