Squeezed states of light One of the energy amplification mechanisms that produce huge energy increase within the NAE is squeezed light. In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value. When the uncertainty of the location of a particle (photon in our case) is determined through localization, the energy of that particle increases in direct proportion. IN LENR+, we are dealing with photon number squeezed light. A state is defined to be photon-number-squeezed if its photon-number uncertainty u(n) falls below that of the coherent state, (n)^1/2 How do we know we have a case for squeezed light? One of the characteristics of squeezed light is that two photons are replaced by a single photon of twice the frequency. Such frequency amplification is seen in LENR when the frequency of the infrared light that enters the NAE is amplified in frequency to the EUV range. Quote from page 174 of the reference: Photon anticorrelations can also be introduced by coincidence decimation, which is a process in which closely spaced pairs of photons are removed from the stream (figure 22(c)). Optical second-harmonic generation (SHG), for example, is a nonlinear process in which two photons are exchanged for a third photon at twice the frequency. Both photons must be present within the intermediate-state lifetime of the SHG process for the nonlinear photon interaction to occur. Again, the removal of closely spaced pairs of events regularizes the photon stream. The process of decimation is defined as every Nth photon (N = 2,3, ...) of an initially Poisson photon stream being passed while all intermediate photons are deleted. The passage of every other photon (N = 2) is explicitly illustrated in figure 22(d). The regularization effect on the photon stream is similar to that imposed by dead-time deletion. This mechanism can be used when sequences of correlated photon pairs are emitted; one member of the pair can be detected and used to operate a gate that selectively passes every Nth companion photon. In simple terms: When all those infrared photons are packed into that minuscule nanometer sized space, the energy of the magnetic field is hugely amplified by the uncertainty principle. To properly understand LENR+, we may now need to undertake the mastery of quantum optics.
