If I split coherent state light in half (by a beam splitter) are the 2 output intensities correlated?
From what I have been told and understand, if I use a simple beamsplitter to split coherent state light, I will obtain 2 coherent states as a result.
Are the intensities of these two output states ...

Does the number of photons in a displaced coherent state is same as the original coherent state? [closed]
Lets say I receive a quantum state $|\alpha\rangle$ with number of photons $N$ and I displace this state by $\alpha$ $\hat D(\alpha)$ so the resultant state is $|2\alpha\rangle$ with same number of ...

Coherent state and $m$-photon added coherent state
How is the coherent state differ from $m$-photon added coherent state? Because coherent state itself a state which is superposition of photons.

Can laser light be described by individual photons?
If laser light is described by a coherent state, a macroscopic quantum state, to what extent
does it make sense to speak of individual photons in laser light?
And if the laser is attenuated to be a ...

What is the simplest model for the creation of a coherent state from stimulated emission in a laser?
I am interested in explicitly doing the math for what is decribed in this answer.
Specifically, I am interested in the simplest model for the creation of a coherent state from stimulated emission in a ...

Experimental examples of how to realize the photon coherent state
As well known in the theory of quantum optics, the photon coherent state is defined by
$$\hat{a}|\alpha\rangle = \alpha|\alpha\rangle$$
where $\hat{a}$ is the annihilation operator. Explicitly this ...

Are Bi-photons and Fock States (with $N=2$) the same?
I've been researching about quantum states of light, and I came across with both terms. For what I understand of both, I think they are the same (entangled individual photons with same position and ...
