    I Energy-time versus time bin DOF

    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...

    I Energy-time versus time bin DOF

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

    I Energy-time versus time bin DOF

    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) ?

    I Can superdense coding be achieved without quantum memory?

    In superdense coding how can BSA be performed on the second of a pair of hyperentangled photons if the photon that was sent sometime earlier was measured on arrival? Would not the measurement have destroyed the entanglement? I’m trying to understand superdense coding as set out in this paper...
