Core Principles & Analysis

• Nonclassical light is sub-Poissonian: the standard deviation of photon counts is less than the mean number of photons.
• Fock states (photon number states) have a well-defined number of photons while the phase is totally undefined.
• Squeezed light exhibits reduced noise in one quadrature component.
