Photon Number Distributions and Phase Distributions of Squeezed States
The squeezing angle, that is the phase with minimum quantum noise, has a large influence on the photon number distribution of the light wave and its phase distribution as well.
For amplitude squeezed light the photon number distribution is usually narrower than the one of a coherent state of the same amplitude resulting in sub-Poissonian light, whereas its phase distribution is wider. The opposite is true for the phase-squeezed light, which displays a large intensity (photon number) noise but a narrow phase distribution. Nevertheless the statistics of amplitude squeezed light was not observed directly with photon number resolving detector due to experimental difficulty.
For the squeezed vacuum state the photon number distribution displays odd-even-oscillations. This can be explained by the mathematical form of the squeezing operator, that resembles the operator for two-photon generation and annihilation processes. Photons in a squeezed vacuum state are more likely to appear in pairs.

Famous quotes containing the words number, phase, squeezed and/or states:
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
“The Indians feel that each stage is crucial and that the child should be allowed to dwell in each for the appropriate period of time so that every aspect of his being can evolve, just as a plant evolves in the proper time and sequence of the seasons. Otherwise, the child never has a chance to master himself in any one phase of his life.”
—Alan Quetone (20th century)
““Tonight,
I must go to that lucky man
and in the blinding dark.”
Thinking that,
a respectable woman,
eyes squeezed shut,
practices walking in her house.”
—Hla Stavhana (c. 50 A.D.)
“The city of Washington is in some respects self-contained, and it is easy there to forget what the rest of the United States is thinking about. I count it a fortunate circumstance that almost all the windows of the White House and its offices open upon unoccupied spaces that stretch to the banks of the Potomac ... and that as I sit there I can constantly forget Washington and remember the United States.”
—Woodrow Wilson (1856–1924)
