Quantum State Quotes

When I hear of Schrödinger's cat, I reach for my pistol.

Somewhere around the place I've got an unfinished short story about Schrodinger's Dog; it was mostly moaning about all the attention the cat was getting.

The mathematics of quantum mechanics very accurately describes how our universe works. And it tells us our reality is continually branching into different possibilities, just like a coral.

I love existing in pre big bang conditions.

If you have nothing in quantum mechanics, you will always have something.

An atom is a hierarchy of different states of information that define the statistical likelihood of finding a particle here or there at the time of observation.

There can never be two or more equivalent electrons in an atom, for which in a strong field the values of all the quantum numbers n, k1, k2 and m are the same. If an electron is present, for which these quantum numbers (in an external field) have definite values, then this state is 'occupied.'

Faith is not so much a binary pole as a quantum state, which tends to indeterminacy when closely examined.

Amplifying atoms is more subtle than amplifying electromagnetic waves because atoms can only change their quantum state and cannot be created. Therefore, even if one could amplify gold atoms, one would not realize the dreams of medieval alchemy.

Now I existed solely thanks to the quantum paradox, my brain a collection of qubits in quantum superposition, encoding truths and memories, imagination and irrationality in opposing, contradictory states that existed and didn't exist, all at the same time.

When you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.

It seems to me that we must make a distinction between what is "objective" and what is "measurable" in discussing the question of physical reality, according to quantum mechanics. The state-vector of a system is, indeed, not measurable , in the sense that one cannot ascertain, by experiments performed on the system, precisely (up to proportionality) what the state is; but the state-vector does seem to be (again up to proportionality) a completely objective property of the system, being completely characterized by the results it must give to experiments that one might perform.
