Google Tech Talk: quantum existence

Ron Garret gave a fascinating Google Tech Talk: “The Quantum Conspiracy: What Popularizers of QM Don’t Want You to Know.”

From the abstract:

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 exist.

From two of his slides:

Philisophical Implicaitons:

The classical universe is not “real”

  • There is no (one) classical universe.
  • There is only one quantum universe (which can be viewed as an infinite collection of classical universes).

This is not (quite) as strange as it seems.

  • Even classical reality is not as we perceive it.
  • We are not made of atoms, we are made of classical bits (Correlations without correlata – David Merman).

“We are our thoughts. … We are a simulation running on a quantum computer.” – Ron Garret
