How to simulate Vacuum Fluctuation based Quantum Random Number Generator?

Vacuum Fluctuation based QRNG uses homodyne detection to measure the shot noise (or vacuum noise) which is quantum phenomena. With these fluctuations one can design a RNG. I want to simulate...

Are linewidth of the laser source and vacuum fluctuations measured using the homodyne detection independent?

For Vacuum fluctuations based QRNG source, how will the linewidth of the laser source affects the shot noise. If we decrease the linewidth of the laser source, will we get a better output.

In DPS QKD, how to determine that interference happening at the DLI is actually because of two neighboring photon or a photon and a vacuum state ?

Suppose we are attenuating up to 0.2 mean photon number. So, every RF cycle will not contain a photon. So while providing a 1-bit delay, it is possible that the interference can happen between a...
