Photon number phase uncertainty
Webm, known as the phase state, can be constructed as the superposition of photon number states 0 1 1 m r in m n en r χ = χ= + ∑ (VI-98) where . 2 , 0,1,.... m 1 m m r χ=π = + r (VI-99) and r is a large number, much larger than the important photon-number constituent in a given field excitation. The phase states form a complete orthonormal ... WebOct 1, 1993 · We have experimentally determined all of the quantities involved in the uncertainty relation for the phase and photon number of a mode of the electromagnetic field when the field mode is in a coherent state of small average photon number. This is accomplished by determining the quantum state of the field using optical homodyne …

In a thermodynamic system, the ground state becomes macroscopically occupied below a critical temperature — roughly when the thermal de Broglie … See more WebMay 1, 2016 · Just like position-momentum uncertainty there is a number-phase uncertainty for the EM waves. So although we know what is the mean number of photons that constitutes the beam, we do not know the exact number. On the other hand if your question is about whether one photon can be treated as an EM wave then of course it is yes.
