The Quantum Conspiracy: What Popularizers of QM Don't Want You to Know
Presented by Ron Garret.


Richard Feynman once famously quipped that no one understands quantum
mechanics, and popular accounts continue to promulgate the view that QM is
an intractable mystery (probably because that helps to sell books). QM is
certainly unintuitive, but the idea that no one understands it is far from the
truth. In fact, QM is no more difficult to understand than relativity. The
problem is that the vast majority of popular accounts of QM are simply flat-out
wrong. They are based on the so-called Copenhagen interpretation of QM,
which has been thoroughly discredited for decades. It turns out that if
Copenhagen were true then it would be possible to communicate faster than
light, and hence send signals backwards in time. This talk describes an
alternative interpretation based on quantum information theory (QIT) which is
consistent with current scientific knowledge. It turns out that there is a simple
intuition that makes almost all quantum mysteries simply evaporate, and
replaces them with an easily understood (albeit strange) insight: measurement
and entanglement are the same physical phenomenon, and you don't really
