New Method to Combine Conventional Internet with the Quantum Internet
Context:
A team of researchers from the Institute of Photonics at Leibniz University Hannover have created a novel transmitter-receiver system for sending entangled photons through optical fibres.
Key Highlights:
- This breakthrough could pave the way for the quantum internet, allowing next-generation telecommunications to be routed through optical fibres.
- Colour Synchronisation: The researchers can adjust the colour of a laser pulse with a high-speed electrical signal to match the colour of entangled photons. This allows the integration and separation of laser pulses and entangled photons in the same optical fibre.
- Impact on Data Channels: Previously, entangled photons blocked data channels in optical fibres, limiting conventional data transmission. The new concept allows photons to share the same colour channel as laser light, thus enabling the use of all colour channels for conventional data transmission.
- Security and Quantum Computing: The quantum internet promises eavesdropping-proof encryption that even future quantum computers can’t break, ensuring the security of critical infrastructure.
Implications:
- The practical implementation of hybrid networks is now within reach, thanks to this groundbreaking research.
- By combining the strengths of both conventional and quantum communication, we move closer to a more secure and efficient global network.
