Dark states of quantum search cause imperfect detection
We consider a quantum walk where a detector repeatedly probes the system with fixed rate 1/τ until the walker is detected. This is a quantum version of the first-passage problem. We focus on the total probability P_{det} that the particle is eventually detected in some target state, for example, on...
