Experiments in Quantum Theory

In General > s.a. Complementarity; correlations; history of quantum theory; Interference.
* Idea: The field of "experimental metaphysics" (Shimony) has become a well-developed one, helped both by new experimental techniques, and by the emergence of quantum information science.

> Gedankenexperiments: see bell's inequality; Einstein's Boxes; EPR paradox.

Kochen-Specker Experiment / Theorem > s.a. realism; Topos.
* Idea: Usually interpreted to imply that predictions of non-contextual hidden variable theories cannot agree with Copenhagen quantum mechanics.

Experiments on Superluminal Communication > s.a. causality violation; quantum effects.
* Delayed choice: Name given by Wheeler to a set of experiments on the predictions of quantum mechanics; One prepares a system in some state, and chooses what measurement will be performed on the system only after the preparation; The surprise provided by the original delayed-choice experiment led Wheeler to the conclusion that 'no phenomenon is a phenomenon until it is an observed phenomenon'.

Macroscopic Objects > s.a. classical limit.
* Schrödinger's cat: Thought experiment proposed in 1935 by E Schrödinger; A similar, real experiment was done in 1996 at NIST with a charged beryllium atom instead of a cat; The group demonstrated that the atom could be at two different locations and have two different spin states at the same time, from the interference pattern they observed; > s.a. pilot-wave interpretation.

Types of Experiments > s.a. experiments in physics; foundations; neutron [interferometry]; hidden variables; pilot-wave theory; uncertainty.
* Non-demolition: Technique to make a measurement on a particle without destroying it or absorbing energy from it; An antenna can in principle be used to measure arbitrarily weak classical signals with arbitrary accuracy.
* GHZ experiment / theorem: (Greenberger-Horne-Zeilinger) Demonstrates the impossibility of certain types of local hidden-variable theories.
