Physics: Quantum all the way
How does our classical world emerge from the
counterintuitive
principles of quantum theory? Can we even be sure that the world
doesn't 'go quantum' when no one is watching?
Quantum mechanics is generally thought to govern objects such as
individual atoms, not lumps of matter like these bridges, which contain
tens of billions of atoms.
It is an ambitious goal. But Schwab, based at Cornell University in
Ithaca, New York, is one of several experimentalists seeking to probe
one of the great conundrums of modern physics: the quantum–classical
transition.
“There's good reason to believe that we are just as much part of the
quantum world as are the tiny atoms and electrons that sparked quantum
theory in the first place,”
Some physicists think that how quantum behaviour should be interpreted
remains as unclear today as it was when Niels Bohr, Werner Heisenberg,
Albert Einstein and others were developing (and arguing over) the
theory. “This is an emotional issue,” says quantum technologist Chris
Monroe from the University of Maryland in College Park. “Some insist
that there is no problem; others insist that there must be an infinity
of universes, each with their own classical description of a definite
quantum state.”
