Hybrid CV-DV Quantum Communications and Quantum Networks

Case ID:
UA22-131
Invention:

This technology is a robust and efficient quantum network that allows for a large number of entangled states to be delivered over the nodes in the network. The network makes use of simultaneous discrete variable (DV) and continuous variable (CV) entanglement unlike existing state of the art quantum networks, making it ideal for serving as the backbone of a quantum internet.

Background: 
Quantum communication networks are important because they provide a higher level of security than traditional communications. To protect traditional communications, encryption is typically applied. But as computers get faster, they can break encryption protocols more easily, and encryption often has other security flaws and can slow down communications. Quantum communication, on the other hand, is inherently more secure and has the potential for higher speeds. 

Hybrid CV-DV quantum states can be entangled and measured when working with light-based communications. Traditionally, when creating light-based quantum networks, the light is either treated like a particle, leading to DV-based quantum technologies, or the light is treated like a wave, leading to CV-based quantum technologies. However, recent research has suggested a third approach, the hybrid CV-DV approach, which does both. This technology serves to build upon that research to create a practical and effective implementation of hybrid CV-DV quantum communications.

Applications: 

  • Quantum communication networks
