| description | A two-qubit system in quantum information theory is the simplest bipartite quantum system and its concurrence
for pure and mixed states is well known. As a subset of two-qubit systems, Bell-diagonal states can be depicted
by a very simple geometrical representation of a tetrahedron with sides of length 2
√
2. Based on this geometric
representation, we propose a simple approach to randomly generate four mixed Bell decomposable states in which
the sum of their concurrence is equal to one. |
