Hi everyone :]
This is my first time here. I have this Quantum Optics question (though I don't believe there is anything QM about this question, so please let me know if I've incorrectly placed this thread) as part of a (nonmarked) assignment.
Here's the question:
"What is the maximal bandwidth that the quantum source may emit single photons, such that after traveling the long optical fiber of 100km the chromatic dispersion effects allow time-bin encoding with 3 ns delay, given the wavelength is at the transmission optimum of 1550 nm?"I am.. completely lost. A little back story: I study post quantum cryptography and am funded by a post quantum/QKD research group which is quite fond of assigning deliverables on tangentially related material. I have absolutely no background in in QM/QKD/really physics in general.
I would appreciate any and all advice :)
