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.
Discovered back in 1980, quantum dots are incredibly small semiconductor particles ranging in diameters of between 2 and 10 nanometres. They have a unique optical property in that they can absorb light energy, achieve an ‘excited’ state, and then release photons as they return to their original ‘ground’ state. According to their size, quantum dots fluoresce to emit light of different colours when light energy is applied to them.
