I have seen four two qubit entangled states of the form:
$ \frac{1}{\sqrt{2}} \left | 00 \right > \pm \left | 11 \right >$
$ \frac{1}{\sqrt{2}} \left | 01 \right > \pm \left | 10 \right >$
I want to write a most general two qubit entangled state. I presume it can be of the form:
$ \alpha \left | 00 \right > + \beta \left | 11 \right > + \gamma \left | 01 \right > + \delta \left | 10 \right >$
where the $\alpha, \beta ...$ are complex numbers. If this is correct, How can I parametrize these constants using least number of free parameters?
