levin irmak Posted October 11, 2011 Share Posted October 11, 2011 short description of quantum optics taken from wikipedia. Quantum optics is a field of research in physics, dealing with the application of quantum mechanics to phenomena involving light and its interactions with matter. can some one tell me how does measuring a single polarized photon affect its behavior afterwards ex; when it goes through another polaroid. ? isn't there any way to measure it without disturbing it? Can we develop a theory that reasons for the disturbance of the subatomic particles and a way to determine a non-disturbing measurement of the subatomic particles? sincerely yours, Link to comment Share on other sites More sharing options...

A photon with an undetermined polarization does have a chance of passing through that polarizer. You can conceivably do measurements that do not determine the state of the particle to arbitrarily small uncertainty and do a large number of measurements, which would give you an average value of the polarization and/or measure some correlated state of the photon and determine the polarization from that other measurement. I think both approaches have been used in "weak measurement" experiments. Link to comment Share on other sites More sharing options...
