Homework Statement
Given a density matrix of three qubit pure state, how can I know after do some transformation, this state belong to what class?. Class I mean here, either separable state, biseparable, GHZ state or W state?
I mean here what is the indicator to me classify it?
It is the indicator must has been done by measuring the state with certain measure?
If yes (mean have to measure it) , what the range that must be satisfy of each class (class-separable,biseparable, GHZ and W).
Please help me.
thank you
