quantum measurement has the effect of ‘‘magnifying’’
one of the outcomes of quantum superposition
probabilistic, sequential
Only at this point do indeterminacy and probabilities

QUANTUM WORLD CLASSICAL WORLD
Quantum computation is
deterministichighly (exponentially) parallel
unitary
described by Schrodinger equationusing entanglement as a computational
resource

Classical computation is
working with real probabilities
