Quantum Photonics: Improving Future Of Light-Based Computing
It is the study of producing, modifying, and detecting light in regimes where individual quanta of light field (photons) controlled
Future technologies including quantum metrology, quantum computing, and quantum key distribution are also anticipated to be greatly advanced by quantum photonics
Waveguides and other components made from miniature parts using sophisticated lithographic processes are naturally phase stable (coherent) and don’t need optical alignment
Miniaturization: A smaller system size results in an order of magnitude reduction in size, weight, and power consumption
Experiment size: A device that is just a few square centimeters in size may have a large number of optical components
There are several practical distinctions between quantum and conventional photonic integrated circuits, despite the fact that both employ the same basic components
Quantum communication: It may improve information security via QKD and other methods. Eavesdropping can be stopped using the non-cloning theorem
