Abstract
Employing the s-ordered operator expansion formula and the technique of integration within s-ordered product of operators, we derive a new photocount formula for general parameter s, which can unify the two quantum-mechanical photocount formulas in Opt. Lett. 33, 433 (2008). It brings convenience to photocount’s calculation when system’s density operator is known. The s-parameterized photocount formula for pure number state density operator is firstly derived.
