- Quantum dots tuned to C-Band telecoms frequencies will be compatible with existing fibre-optic telecoms networks
- This offers enormous potential for global quantum telecoms networks and the quantum internet of the future
- Tiny semiconductor particles can, according to their size, emit any colour of light
- Indistinguishable photons to enable scalable schemes of quantum comms
At some point, maybe in 10 years or so but more likely within a generation, quantum telecoms and the quantum internet should be the global norm for the generation, distribution, storage and processing of data via quantum bits (qubits) linked across different quantum nodes via quantum states of light.
To work across fibre-optic networks and within the bounds of accepted, standardised methodologies and compatibilities (not to mention the immutable laws of physics), long-distance quantum telecoms networks will need quantum repeaters operating in telecoms frequencies. Semiconductor quantum dots (QDs) show great promise in this regard.
