Security proof of QKD using Entropic Uncertainty relations

In this talk, I will describe the use of entropic uncertainty relations in QKD security proofs. I will show how this proof method requires a bound on the classical statistics of the underlying quantum state, and thus ultimately reduces to a sampling problem. I will then describe how the sampling problem is addressed in the literature under certain unphysical assumptions on the QKD hardware. Finally, I will describe how these assumptions can be removed, thereby rendering this proof technique applicable to practical scenarios.
