We propose a quantum string comparison method whose main building blocks are a specially designed oracle construction followed by Grover's search algorithm. The purpose of the oracle is to compare all alphabets of the string in parallel. This requires a unique input state preparation, which when combined with some ancillas will result in a deterministic binary success and failure compare outcome.
