Abstract
We derive two quantum-mechanical photocount formulas when a light field’s density operator ρ is known; one involves ρ’s coherent state mean value and the other involves ρ’s Wigner function; when this information is known, then using these two formulas to calculate the photocount would be convenient. We employ the technique of integration within an antinormally ordered (or Weyl-ordered) product of operators in our derivation.
