SAAB 2 ( [ A , B]ITY (5) 4. Consider the spin operators: Sx = =[IB) (al + la)(B1] Sy = = [IB) (al - 10)(81] S z = [la) (al - 18)(B11, where la) and [) are ortho-normal states (meaning (ala) = (B|B) = 1 and (alB) = (B|a) = 0). Now that you have derived the uncertainty relationship, show that Eq. (5) is valid for this system by showing for the state |a) ASIASy 2 2 /| (9)
