Consider a physical system whose three-dimensional state space is spanned by the orthonormal basis formed by the three kets {Je1>, Je2>, Je3>}. In the basis of these three vectors, taken in this order, the Hamiltonian H^ and the two operators B^ and D° are defined by: 3 i 0 -i 3 0 0 2 7 i 1 - 0. 2a A= hwo B= bo -i 7 1+i D= 2a 1+i 1-i 6. 2a -3a where wo and bo are constants. Also using this ordered basis, the initial state of the system is given by: (e1|v(0) (e2| v(0)) (e3| v(0)) 2 |v(0)) = 3 6 Q: What is the probability that the system will be found in the ground state after measuring H at t + 0? Q: After measuring H at t + 0, the operator B was measured. What is ± AB?
