Single qubit and its logic gates

Thanks for putting this together! Really appreciated the animation - it helped me visualize qubit rotation.

woow what an interesting video, nice animation! ❤️

Great vídeo and great animations! Very clear and to the point!

Since you understood this, let me ask… A qubit can represent more than one bit, is it due to its spin direction and angle ? For example, a qubit can spin up or down, therefore the spin up can represent 1 and spin down can represent 0, and thus one qubit can represent one bit. In addition to up/down spin, it can also spin at an angle, for example, 90 degrees, 180 degrees or 270 degrees. So, from this degree distinction, a qubit can represent more bits. Thus, more angles more bit representation. My question is, how do you detect and measure the direction and angle of a qubit ?

Great resource!

What happens if you smash together 2 entangled particles? What happens when you create a delayed choice quantum eraser that chooses non to function after the delay? What happens if you use qubits like electrons in a typical classical computer?

At 11:24: Did should the Rx matrix be Ry and vice versa? Also, for Rz, we can factor out the global phase leaving a 1 at the (1,1) matrix element right?

[@eurasian23]

so is H ket 1 equal to delta E?

OMG so far over my head. WOW

This seems intentionally over-complicated. Bra is a row index into a matrix, and ket is the column index.
