Quantum networking has achieved stable and high-fidelity communication through existing fibre networks with no missing data or data corruption.
A recent experiment demonstrates that quantum data can be safely transmitted through the same fibre cables used for the internet today, with a 99% accuracy rate.
The system utilizes entanglement, a connection between two particles that remains even when they are far apart, by sending special light particles called entangled photons through telecom fibres.
Scientists used atoms of ytterbium-171 (¹⁷¹Yb) to match the wavelength with the telecom range, creating photons at a wavelength of 1389 nanometres, which fits directly into the telecom range.
Author's summary: Quantum networking achieves high accuracy.
