In physics, a squeezed coherent state is a quantum state that is usually described by two non-commuting observables having continuous spectra of eigenvalues. Examples are position x {\displaystyle x} and momentum p {\displaystyle p} of a particle, and the (dimension-less) electric field in the amplitude X {\displaystyle X} (phase 0) and in the mode Y {\displaystyle Y} (phase 90°) of a light wave (the wave's quadratures).
