Latest Patents

One of Terai's latest patents is a superconducting single-photon detection system. This system includes multiple optical transmission paths through which photons emitted from a light source are transmitted. It features a plurality of superconducting single-photon detectors (SSPDs) that operate independently and correspond one-to-one with the optical transmission paths. Additionally, a superconducting logic circuit multiplexes the first pulse signals output from the SSPDs. The photon entry time varies for each optical transmission path, ensuring that the difference in entry time exceeds the pulse width of the second pulse signals output from the superconducting logic circuit.

Another notable patent is a photon detection device that comprises a superconducting photon detector array. This array consists of several superconducting photon detectors (SPDs) arranged in a specific configuration. The device includes first transmission lines connected to the SPDs to transmit detection currents, an address information generation circuit that creates an address information signal based on the detection current, and a second transmission line that is magnetically coupled to all first transmission lines. A time information generation circuit is also included, which generates a time information signal indicating when a photon is incident on the superconductive photon detection SPDs.
