What is the Deutsch-Jozsa algorithm?

The Deutsch-Jozsa algorithm is a quantum algorithm that solves the Deutsch-Jozsa problem, which is a problem in computer science and mathematics. The algorithm determines whether a given function is constant or balanced, meaning it returns the same output for all inputs or returns different outputs for at least half of the inputs, respectively. The Deutsch-Jozsa algorithm uses quantum superposition and interference to provide a quadratic speedup compared to classical algorithms, making it a significant advancement in the field of quantum computing.
