A quantum observable is a measurable operator whose corresponding property of the state can be determined by some sequence of physical operations ("observation"), such as submitting the system to various electromagnetic fields and eventually reading a value. In systems governed by classical mechanics, any experimentally observable value can be shown to be given by a real-valued function on the set of all possible system states.

Non-observance and the Schrödinger equation
I was thinking today about configurations where one measures that a certain observable is not in a certain state.
I was getting confused about what this means for decoherence.
If I observe a detector …

Proof of Canonical Commutation Relation (CCR)
I'm not entirely sure why some people are calling this is an "axiom".
$$
\begin{align}
[x, p_x]\Psi &= (x p_x - p_x x) \Psi\\
&= -i\hbar \left[ x\frac{\partial}{\partial x} - \frac{\partial}{\partial …
