> We know that things that follow quantum rules, such as atoms,
> electrons or the photons that make up light, are full of surprises.
> They can exist in more than one place at once, for instance, or exist
> in a shared state where the properties of two particles show what
> Einstein called "spooky action at a distance", no matter what their
> physical separation. Because such things have been confirmed in
> experiments, researchers are confident the theory is right. But it
> would still be easier to swallow if it could be shown that quantum
> physics itself sprang from intuitive underlying principles.
> One way to approach this problem is to imagine all the theories one
> could possibly come up with to describe nature, and then work out
> what principles help to single out quantum physics. A good start is
> to assume that information follows
> Einstein's special relativity and cannot travel faster than light.
> However, this alone isn't enough to define quantum physics as the
> only way nature might behave. Corsin and Stephanie think they have
> come across a new useful principle. "We have found a principle that
> is very good at ruling out other theories," says Corsin.
> In short, the principle to be assumed is that if a measurement yields
> no information, then the system being measured has not been
> disturbed.
