If it is dead and still alive it must be a zombie! In case you search for a cool “Fedora 19″ shirt getdigital a german company for geek stuff has a new shirt in his sortiment, Schroedingers Zombie Cat. Maybe I should draw something similar in blue….

That equation for the “ψ” vector (for hysterical reasons also known as the “wavefunction”) is not very nice.
The cat can be considered a qubit, a superposition of states “|Dead>” and “|Alive>”. These states can be superposed, so the cat can be either fully “|Dead>”, fully “|Alive>” or a weighted sum of both extrema, with the weights being complex numbers (c1,c2). (c1,c2) is a vector in ℂ² of length 1. If the cat is a Zombie in addition to being both dead and alive, does this mean we have a tristate quantum bit? Maybe…
Anyway, the formula for the Bloch Sphere should be applied
http://en.wikipedia.org/wiki/Bloch_sphere
ψ =
cos(θ/2) * |Dead>
+
e^(i*φ) * sin(θ/2) * |Alive>
Very simple!
