| Feb 28, 2018 at 11:38 | comment | added | Bardeen | you are correct qi here is taken to be $$\ p_{i|j}$$ | |
| Feb 28, 2018 at 11:32 | comment | added | Bardeen | the two psis are going to become pho multiplied by $P_j $ in two sides and the sum of $\frac{1}{p_{j|i}}$ is $p_j$ | |
| Feb 28, 2018 at 11:07 | comment | added | StarBucK | @001 I don't understand what you mean precisely. For example for me the term should be $\frac{q_i}{p_{j|i}}$, where $q_i$ is the statistical probability (not quantum) to have the state $|\psi_i\rangle$. And $p_{j|i}$ is the quantum probability to be in the state $j$ after measurement when we prepared the state $|\psi_i\rangle$ at the beginning. | |
