Thanx 👍🏼👍🏼

Yo, best explaination yet

[@arisoda]

Any plans on making advanced linear algebra videos? It's an intuitive subject, so suitable for this style of teaching

So, each rotation matrix defines 2 complex numbers, one per row, that are multiplied with with spin up and down respectively to apply a rotation to a single qbit?. But if it is an entangled state, with 4 elements in the state vector, don't you need 4x4 matrixs?

[@YedaiHomeostatico]

oh, each rotation in exectuted by np.dot(statevector, rotationmatrix) and for two qbuit the 4x4 rotation matrix is created by np.kron(r2,r2) witch is a tensor product
