Overview

The Deutsch-Jozsa algorithm, developed by David Deutsch and Richard Jozsa in 1992, is a quantum algorithm that demonstrates the power of quantum computing over classical computing. This algorithm solves a problem called the Deutsch-Jozsa problem, which involves determining whether a given function is constant or balanced.
