Turn a phase difference into a search advantage.
Select any state, mark it with a phase flip, then use interference to reshape the odds without checking every state.

Select any state, mark it with a phase flip, then use interference to reshape the odds without checking every state.
In an eight-state quantum database, search begins with a balanced superposition where each state shares an identical amplitude. Clicking flip target phase inverts the target amplitude below the zero line, altering its phase while leaving probability unchanged. Executing interference reflects each amplitude across the lowered mean, suppressing non-target states and concentrating probability into the target.
