Energy-time versus time bin DOF

[Armchair]

With respect to entanglement, is the energy-time degree of freedom continuous whilst the time bin DOF is discrete or is there some other difference (if any) ?

What do you mean by "the energy-time degree of freedom" and "the time bin DOF"?

What do you mean by "the energy-time degree of freedom" and "the time bin DOF"?

The means by which information can be encoded when using photons to hold qubits as part of hyperentanglement schemes.

Sorry, this doesn't help. Do you have a reference? (Textbook or peer-reviewed paper.)

It looks like this is the preprint on arxiv:

https://arxiv.org/abs/1601.02032

I see the term "time-bin degree of freedom" used there (though I'll have to read through the article when I get a chance to understand what they mean by it), but I don't see the term "energy-time degree of freedom" anywhere in the article. So I still don't know what you mean by that term.

In the first part of the particular section I mentioned-

''...Hyperentanglement has attracted much attention in recent years due to its promising applica- tions. Besides the traditional DOFs of photons, the energy-time and orbital angular momentum DOFs also have been considered in constructing hyperentanglement [63, 64]...''

thanks for your feedback.

Ok, this just references some other papers; the terminology isn't explained in this paper, as far as I can tell. My initial reaction is that this looks like an open area of research, so discussion of it here will probably be limited.

This paper may help. Seems to be in a proper journal.
