Quantum Networking Achieves 99% Accuracy Using Optical Fiber Cable
Quantum networking achieves stable and high-fidelity communication through existing fibre networks with no missing data or data corruption.
A new quantum networking experiment demonstrates that quantum data can be safely transmitted through the same fibre cables used for the internet today, with a system achieving 99% accuracy.
The system utilizes entangled photons, sent through telecom fibres, and exploits entanglement, a link between two particles that remains connected even when they are far apart.
- Earlier experiments suffered from data loss due to a mismatch between the wavelength of the light used for communication and that used in fibre cables.
- In this new approach, scientists used atoms of ytterbium-171 (¹⁷¹Yb) to match the wavelength with the telecom range by creating photons at a wavelength of 1389 nanometres.
