OPTICAL TRANSMITTER FOR A QUANTUM KEY DISTRIBUTION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048242 titled 'OPTICAL TRANSMITTER FOR A QUANTUM KEY DISTRIBUTION SYSTEM

Simplified Explanation

The abstract describes an optical transmitter for a quantum key distribution (QKD) system. The transmitter includes a multi-modal laser, a wavelength tuneable laser, and a modulator. The wavelength tuneable laser injects light into the cavity of the multi-modal laser, causing it to output light at a selected wavelength. The modulator controls the phase shift between successive pulses output by the transmitter.

  • The transmitter uses a multi-modal laser and a wavelength tuneable laser to generate pulses of light at a selected wavelength.
  • The modulator allows for precise control of the phase shift between successive pulses.
  • The technology is designed for use in a quantum key distribution system, which is a method of secure communication using quantum mechanics principles.

Potential applications of this technology:

  • Quantum key distribution systems: The optical transmitter can be used in QKD systems to securely transmit cryptographic keys using quantum mechanics principles.
  • Secure communication: The technology can be used to establish secure communication channels, ensuring the confidentiality and integrity of transmitted data.

Problems solved by this technology:

  • Security vulnerabilities: The technology addresses the need for secure communication by utilizing the principles of quantum mechanics to prevent eavesdropping and ensure the confidentiality of transmitted data.
  • Key distribution: The transmitter enables the generation and distribution of cryptographic keys, which are essential for secure communication.

Benefits of this technology:

  • Enhanced security: By utilizing quantum mechanics principles, the technology provides a high level of security, making it difficult for unauthorized parties to intercept or tamper with transmitted data.
  • Efficient key distribution: The transmitter allows for the generation and distribution of cryptographic keys, enabling secure communication without the need for pre-shared keys or complex key exchange protocols.


Original Abstract Submitted

an optical transmitter for a quantum key distribution (qkd) system, the transmitter comprising: a multi-modal laser; a wavelength tuneable laser arranged to inject light into a cavity of the multi-modal laser, so as to cause the multi-modal laser to output light at a selected wavelength for use in generating pulses to be output by the transmitter; and a modulator for controlling a phase shift between successive pulses output from the transmitter.
