Do quantum logic gates perform measurements? (collapse the wavefunction)(adsbygoogle = window.adsbygoogle || []).push({});

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...
