Photonic quantum networks positioned as future foundation of quantum connectivity
Semiconductor Review Europe has highlighted the growing role of photonic quantum networks as a critical building block for the future quantum internet. According to the report, these networks, powered by photons that carry quantum information, are emerging as a promising pathway toward ultra secure communication and distributed quantum computing.
The technology relies on quantum nodes such as quantum processors, memory units, sensors and repeaters, which are connected through quantum channels including optical fibre, free space links and satellite based communication. By transmitting quantum states rather than classical signals, photonic quantum networks enable quantum secure data transfer, real time synchronisation between quantum systems and highly precise distributed sensing.
The report notes that the stability and scalability of photonics give these networks a clear advantage over other quantum platforms. Photons can travel long distances with minimal loss, and the industry is working to integrate quantum photonic components onto compact chips to improve practicality and scalability.
Researchers around the world are now developing the key hardware required for these networks, including entangled photon sources, quantum repeaters and integrated quantum photonic circuits, in an effort to support large scale deployment.
With continued progress, photonic quantum networks are expected to play a central role in secure communication infrastructure, the advancement of quantum computing and the growth of emerging quantum enabled applications across science, defence and telecommunications.
