  * 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.

  * Delayed choice: The 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
    (one that will detect particlelike properties or wavelike properties) 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'; Results obtained in 2007 by A Aspect et al with single
    photons, and by A Truscott in 2015 with atoms confirm the predictions of quantum mechanics
    and indicate that, barring backward causation, a particle decides whether to be a wave
    or a particle when the measurement is carried out.

  * Schrödinger's cat:
    Thought experiment proposed in 1935 by E Schrödinger; 1996, Real
    experiment done 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; 2016, Demonstration with a large number of photons

Types of Experiments
  > s.a. experiments in physics; foundations;
  realism [including non-local]; 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.
