Conduct of Optical Bell Test Experiments
In practice most actual experiments have used light, assumed to be emitted in the form of particle-like photons (produced by atomic cascade or spontaneous parametric down conversion), rather than the atoms that Bell originally had in mind. The property of interest is, in the best known experiments, the polarisation direction, though other properties can be used. Such experiments fall into two classes, depending on whether the analysers used have one or two output channels.

Famous quotes containing the words conduct of, conduct, optical, bell, test and/or experiments:
“Vulgarity is simply the conduct of other people.”
—Oscar Wilde (1854–1900)
“The mere fact of leaving ultimate social control in the hands of the people has not guaranteed that men will be able to conduct their lives as free men. Those societies where men know they are free are often democracies, but sometimes they have strong chiefs and kings. ... they have, however, one common characteristic: they are all alike in making certain freedoms common to all citizens, and inalienable.”
—Ruth Benedict (1887–1948)
“There is an optical illusion about every person we meet.”
—Ralph Waldo Emerson (1803–1882)
“I was thinking of a son.
The womb is not a clock
nor a bell tolling,
but in the eleventh month of its life
I feel the November
of the body as well as of the calendar.”
—Anne Sexton (1928–1974)
“Experimental work provides the strongest evidence for scientific realism. This is not because we test hypotheses about entities. It is because entities that in principle cannot be ‘observed’ are manipulated to produce a new phenomena
[sic] and to investigate other aspects of nature.”
—Ian Hacking (b. 1936)
“A country survives its legislation. That truth should not comfort the conservative nor depress the radical. For it means that public policy can enlarge its scope and increase its audacity, can try big experiments without trembling too much over the result. This nation could enter upon the most radical experiments and could afford to fail in them.”
—Walter Lippmann (1889–1974)
