Description |
The shot noise of photons is a big barrier in a range of applications like the coherent processing of signals, quantum communication and quantum metrology. Use of squeezed light would be a way out and great progress has been made towards producing light with large squeezing. In this talk I would discuss a newer possibility i.e. the use of sources of light which produce entangled photon pairs. I would describe the progress made using entangled photon pairs and the challenges ahead. |
