Exact rate analysis for quantum repeaters with imperfect memories and entanglement swapping as soon as possible
We present an exact rate analysis for a secret key that can be shared among two parties employing a linear quantum repeater chain. One of our main motivations is to address the question whether simply placing quantum memories along a quantum communication channel can be beneficial in a realistic set...
