In the course of the interaction of those two worlds, when the microscopic systems interact with classical objects, the quantum world collapses to the classical one. In some way, in this interpretation, the quantum world is an unstable one. ...

The Power of Quantum Advice
... Motivating Question: How much useful computational work can one “store” in a quantum state, for later retrieval? If quantum states are exponentially large objects, then possibly a huge amount! Yet we also know, from Holevo’s Theorem, that quantum states have no more “general-purpose storage capacity ...

Simulating Physics with Computers Richard P. Feynman

If physics is too hard for classical computers, then build a physical computer that exploits that power. “It does seem to be true that all various field theories have the same kind of behavior, and can be simulated every way.” Example: phenomena in field theory imitated in solid state theory (e.g, s ...
