Latest Patents

One of Gupta's latest patents is an "Apparatus and method for adjusting the phase-modulator's modulating signal time reference in a quantum-key-distribution system." This invention relates to quantum key distribution (QKD) and introduces an apparatus and method for adjusting the phase modulator's modulating signal time reference in a phase-based QKD system. The system includes a pulse generator that generates optical pulses and a phase modulator that modulates the phase of each pulse. The apparatus comprises a beam splitter, a 1-bit delay interferometer, two photodetectors, and a processing device. The processing device measures the average power at both legs of the interferometer to detect delays and aligns the phase modulator with the pulse generator accurately.

Another notable patent is for a "mirrored serial interface (MSI) for transferring data." This invention pertains to a mirrored serial interface for accessing peripherals through a four-wire serial interface. It features a serial peripheral protocol with a looped-back mechanism, ensuring data integrity by comparing the contents of the source data line with the destination line at every clock edge.
