What is a commutation relation in quantum mechanics?
In quantum mechanics, the canonical commutation relation is the fundamental relation between canonical conjugate quantities (quantities which are related by definition such that one is the Fourier transform of another).
What is a commute in quantum mechanics?
Answer.
A commutator in quantum mechanics tells us if we can measure two 'observables' at the same time.
If the commutator of two 'observables' is zero, then they CAN be measured at the same time, otherwise there exists an uncertainty relation between the two.
How do you prove commutation relations?
Q) as a first order differential operator chosen to match the commutation relation.
To prove the relation when Q and P are given, simply apply both sides to an arbitrary state vector and check that one gets the same result.
Commutators test operators.
If two operators act on a state in such a way that their order is important, then the two operators do not commute.
Non commuting operations are not too hard to understand.
Consider the operations of baking a cake and icing the cake.
