From: The deterministic pattern matching based on the parameterized quantum circuit
The comparison of the results of image pattern matching using different numbers of CNOT gates based on Long’s algorithm. The red bar represents the output of the case with more gates and the blue one represents that with fewer gates. The outcome shows that the successful probability of completing pattern matching is considerably enhanced and the ‘failure’ (not exactly) probability, i.e., the value of bar ‘rest’ greatly depressed
