Do quantum logic gates perform measurements? (collapse the wavefunction)
For example:
If I apply a cNOT gate to a pair of cubits with wavefunction 1/[tex]\sqrt{2}[/tex] |10> + 1/[tex]\sqrt{2}[/tex] |00>
what would I expect as the result?
1/[tex]\sqrt{2}[/tex] |11> + 1/[tex]\sqrt{2}[/tex] |00>
?
or
1|11>
or
1|00>
or
are the states not entangled? This seems unlikely because it would be cloning...
