Monogamy of multi-qubit entanglement using Rényi entropy
Jeong San Kim, Barry C Sanders · Journal of Physics A Mathematical and Theoretical · 2010
We introduce a class of bipartite entanglement measures based on Rényi-α entropy, namely Rényi-α entanglement with an analytic formula in two-qubit systems for α ⩾ 1. We also show that multi-qubit entanglement has a monogamy inequality in terms of Rényi-α entanglement for all α ⩾ 2.
