But the moment of experience is only one, (today we call it the quantum state).

This is the most similar a quantum state can be to a single point in phase space.

"It seems the rules of engagement have changed in the quantum state."

Instead, they had a quantum state, which was a combination of position and velocity.

The field operator acts on quantum states of the theory.

The basic reason is that no two electrons are allowed to be in the same quantum state.

This is the equation of motion for the quantum state.

Paired up, the gas can again drop in a single quantum state.

Now, this is important if he's fluctuating between quantum states.

The above presentation was limited to a pure quantum state.
