X-states from a finite geometric perspective
It is found that 15 different types of two-qubit X-states split naturally into two sets (of cardinality 9 and 6) once their entanglement properties are taken into account. We characterize both the validity and entangled nature of the X-states with maximally-mixed subsystems in terms of certain param...
