AUTO COMPENSATED QUANTUM KEY DISTRIBUTION TRANSMITTER, RECEIVER, SYSTEM AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048368 titled 'AUTO COMPENSATED QUANTUM KEY DISTRIBUTION TRANSMITTER, RECEIVER, SYSTEM AND METHOD

Simplified Explanation

The abstract describes a patent application for a quantum key distribution (QKD) transmitter apparatus. The apparatus includes various components such as a beam splitter, a first photodetector, an optical storage line, a phase modulator, a polarization rotation mirror, a second photodetector, and processing circuitry.

  • The beam splitter is designed to receive an initial pulse train of optical pulse pairs.
  • The first photodetector is used to detect the optical pulses from the beam splitter.
  • The optical storage line is used to store the detected optical pulses.
  • The phase modulator is responsible for modulating the phase of the stored optical pulses.
  • The polarization rotation mirror is used to rotate the polarization of the modulated optical pulses.
  • The second photodetector is used to detect the modulated and polarized optical pulses.
  • The processing circuitry is responsible for various tasks related to quantum key distribution.

Potential applications of this technology:

  • Quantum key distribution (QKD) is a method used for secure communication, and this apparatus can be used in QKD systems.
  • The technology can be applied in secure communication networks, where the transmission of encryption keys is critical.

Problems solved by this technology:

  • Quantum key distribution ensures secure communication by using the principles of quantum mechanics to detect any eavesdropping attempts.
  • The apparatus provides a reliable and efficient way to generate and distribute encryption keys.

Benefits of this technology:

  • The use of quantum mechanics principles ensures high-level security in communication.
  • The apparatus provides a simplified and efficient method for generating and distributing encryption keys.
  • The technology can be integrated into existing communication systems without significant modifications.
