India, Jan. 15 -- City-based Inter-University Centre for Astronomy and Astrophysics (IUCAA) has developed an indigenous technology called 'PhotonSync' that can convert ordinary telecom optical fibres into ultra-stable quantum channels. The development comes after 2025 was observed by UNESCO as the centenary year of quantum mechanics, marking a new phase for quantum science and technology worldwide.

One of the biggest challenges in building quantum networks is that normal optical fibres are affected by temperature changes, vibrations, seismic activity and other environmental factors which add noise to photons travelling through these fibres, making it difficult to transmit quantum information accurately. PhotonSync creates a phase coheren...
