BREAKING: New Phase of Matter

Quantum computers are more likely to hit the limits of your model of physics and not the limit of physics itself. Our models of physics would have to be perfect and have no edge cases or unexplainable affects for simulation to test the boundaries of actual physics. 

Speaking of quantum mechanics, does anyone else find it infuriating that people studying this field avoid the topic of determinism. If you entangle two particles and let them stay entangled, this could just prove determinism at for the degree that they are entangled. It would be strange for one particle to spontaneously lose entanglement unless there is a cost to maintaining it. Scary. That could go a long way to suggesting that two universes that start with the same amount of energy and therefore matter under the same conditions, unfold the same way.

It's possible your future is a quantum mechanical construct.
