Squeezed Light: Darker Than Dark

Harry J. Kimble

In the bizarre world of quantum optics, it's possible to make light that is darker than ordinary darkness, and other even stranger things.

Abstract Light waves, which have almost no physical properties, are an abstract mathematical concept rather than an objective description. Confused by a set of dark and bright stripes and a sketchy schematic with little relation to the actual result, the double-slit phenomenon was misjudged as being caused by interfering light waves, but this plausible principle implies disastrous flaws. For example, (1) immediately after light passes through the double-slit device, the pattern is generated early or before interference. By changing the device-screen distance, the pattern only scales synchronously without being reconstructed by interference. The pattern with more interference points is darker, but it should be brighter. (2) Light waves can not only be subdivided into many parts but also greatly proliferate. (3) Light waves with missing leading edges outside the screen can still induce much interference. (4) Reflected light waves do not interfere. (5) The effect of polarization direction on interference should not be ignored. (6) Compared with the mathematical model, the location where the dark stripe should appear is actually the brightest spot. The formation principle of multiple regular dark stripes cannot be found. (7) To reflect the quantum property in the interference process, unless all conditions are simultaneously met, interference will not be triggered, and therefore, the principle of interference will be rejected. (8) A light source cannot be produced in a slit that may be in vacuum. (9) In the causality test, to verify the effect of collapse, the photons that have collapsed into particles should be tested again with a double-slit test. (10) The phenomenon of "observed tampering results" is obtained by observation. Has it been tampered with by observation? (11) If light is a wave, then matter and antimatter are conjoined. In conclusion, Newton's particle model is wrong, as is light wave theory.

We propose a scheme for preparing coherent squeezed states of motion in an ion trap based on the multichromatic excitation of a trapped ion by standing- and traveling-wave light fields. The squeezed state is produced when the beat frequency between two standing-wave light fields is equal to twice the trap frequency, and is indicated by a ``dark resonance'' in the fluorescence emitted by the ion.
