We're hearing things in the news these days about Squeezed Light, and how it can be used to improve everything from LIGO detectors, to positional sensors, to Quantum Computing. What is Squeezed Light, what useful applications is it being investigated for, and how does it provide this extra utility/benefit? Squeezed Light is apparently created inside Non-Linear Crystals -- but does it have to remain confined within such crystals or within some special environment like a QED cavity? Can Squeeze Light exist/propagate in regular open space? Can Squeezed Light be used in Holography in the same way that regular light is? It's been said that Squeezed Light exhibits noise levels below that of the ambient noise in the natural Vacuum. Would it be possible in principle to manipulate Squeezed Light through interference, to create a macroscopic zone of space with noise levels that are lower than that of the ambient noise in the natural Vacuum?
