Homework Statement
I have a three qbit state:
[itex](a|00> + b|11>)\bigotimes(c|0>+d|1>) [/itex]
and I need to normalise it, I realize that I could deconstruct it into matrices and work it though and solve it but there must be a more efficient way.
Homework Equations
The Attempt at a Solution
I am unsure really how to proceed from here, I kow that to normalise one does [itex] <\psi|\psi>=1 [/itex] but I am confused because this is a 3 qbit state, would it simply be [itex] ac(ac)^{*} + ad(da)^{*} + bc(cb)^{*} + bd(db)^{*}=1[/itex]?.
