Minimum Uncertainty States for Number-Difference-Phase Uncertainty Relationin NFM Operational Phase Description

摘要

For the Noh, Fougères and Mandel (NFM) operational quantum phase description, which is based on an eightport homodyne-detection, we derive the minimum uncertainty states for the number-difference-phase uncertainty relation. The derivation makes full use of the newly constructed ｜q, τ) representation which is the common eigenvector of the two-mode photon number-difference a+a -b+b and (a + b+)(a+ + b)
