Quantum Networking Achieves 99% Accuracy Using Optical Fiber Cable
Quantum networking has achieved stable and high-fidelity communication through existing fibre networks with no data loss or corruption.
A recent experiment demonstrates that quantum data can be safely transmitted through standard fibre cables used for the internet, with a fidelity of 99%.
The system utilizes entangled photons, which are special light particles connected through entanglement, a phenomenon where two particles remain linked despite distance.
- Entanglement enables secure communication.
- Previous experiments suffered from wavelength mismatch, causing data loss and reduced reliability.
- Scientists used ytterbium-171 (¹⁷¹Yb) atoms to match the wavelength with the telecom range, creating photons at 1389 nanometres.
No data loss or corruption occurs in this quantum networking approach.
Author's summary: Quantum networking achieves 99% accuracy through fibre cables.
