| Abstract: | By introducing the generalized Wigner operator for s-parameterized quasiprobability distribution and employing the technique of integration within ordered product (IWOP) of operators (normally ordered, Weyl ordered or antinormally ordered), we derive two new quantum-mechanical formulas for describing no counts registered on a photonic detector when a light field’s density operator ρ is known, one involves ρ’s s-parameterized distribution function, and the other involves ρ’s coherent state mean value, when these information is known then using the new formulas to calculate no-photocount would be convenient. |
