Squeezing and over-squeezing of triphotons

Nature, 2009
Quantum mechanics places a fundamental limit on the accuracy of measurements. In most circumstances, the measurement uncertainty is distributed equally between pairs of complementary properties; this leads to the 'standard quantum limit' for measurement resolution.

Enhanced squeezing in a squeezed vacuum

Optics Letters, 1990
A quantum theory of multiwave mixing based on a combination of a Langevin quantum regression method and a density operator technique is outlined. The approach is simple, yet general, and is particularly valuable for analyzing complicated media such as semiconductors.

Multimode squeeze operators and squeezed states

Physical Review A, 1990
Multimode squeeze and rotation operators are defined such that they have extremely similar algebraic properties as those of their single-mode counterparts. It is shown that the introduction of {ital N}-mode squeeze operators provides a convenient set of parameters to describe the variances of the quadrature amplitudes in multimode Gaussian squeezed ...
