A NETWORK NODE, A TRANSMITTER AND A RECEIVER FOR QUANTUM KEY DISTRIBUTION OVER AN OPTICAL FIBER NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056294 titled 'A NETWORK NODE, A TRANSMITTER AND A RECEIVER FOR QUANTUM KEY DISTRIBUTION OVER AN OPTICAL FIBER NETWORK

Simplified Explanation

The abstract describes a network node in an optical fiber network that includes a quantum key distribution (QKD) communication unit capable of operating in different modes.

  • The network node has a QKD communication unit that can communicate with other network nodes using CV-QKD and/or DV-QKD modes.
  • A control unit is in place to manage the operation of the QKD communication unit, switching between CV-QKD and DV-QKD modes as needed.
    • Potential Applications:**
  • Secure communication networks
  • Quantum cryptography systems
  • Data encryption and decryption
    • Problems Solved:**
  • Ensuring secure communication in optical fiber networks
  • Preventing eavesdropping and data breaches
  • Enhancing data security and privacy
    • Benefits:**
  • Enhanced security for sensitive data transmission
  • Protection against cyber threats and attacks
  • Efficient and reliable encryption methods


Original Abstract Submitted

a network node configured to operate in an optical fiber network can comprise a quantum key distribution (qkd) communication unit adapted to communicate with another qkd communication unit of at least one other network node of the optical fiber network according to a cv-qkd mode and/or a dv-qkd mode. a control unit can be configured to control the qkd communication unit to operate in at least one of the cv-qkd mode and the dv-qkd mode. the control unit can be configured to switch operation of the qkd communication unit between the cv-qkd mode and the dv-qkd mode.
