Two photon interference experiment | 🗖 nosplit | ↑ parent "Single photon production and detection experiments" | 229
The basic experiment for a photonic quantum computer.
Can be achieved in two ways it seems:
- macroscopic beam splitter and optical table
- photolithography
Animation of Hong-Ou-Mandel Effect on a silicon like structure by "Quantum Light University of Sheffield" published on May 29, 2014: https://www.youtube.com/watch?v=ld2r2IMt4vg No maths, but gives the result clear: the photons are always on the same side.
- quantum dot source. TODO how do you produce identical photons from two separate quantum dots? See also: quantum dot single photon source.
- superconducting nanowire detector. So the device has to be cooled then? Video 140. "Jeremy O'Brien: "Quantum Technologies" by GoogleTechTalks (2014)" https://youtube.com/watch?v=7wCBkAQYBZA&t=2497 however says that semiconducting devices can also be used
