A particle is at t = 0 seconds and is in the |H> state. This particle has the orthogonal states |H> and |V>. Usually, these particles start in the state |'> = cos' |H> + sin' |V> with an angle of 30 degrees. We also have these states for the particle:

|C_R> = 1/2 |H> + i/2 |V>

|C_L> = 1/2 |H> - i/2 |V>

At time = 0 seconds and when the particle is in the |H> state, how much time will it take to be in the |V> state?
