Part of the Quantum Computing: A Complete Learning Path series on malcolmlow.com . Following our earlier analyses of the single-qubit Deutsch Algorithm and Phase Kickback , this guide scales the formulation to multi-qubit registers with the Deutsch-Jozsa Algorithm . In 1985, David Deutsch proposed the first quantum algorithm that demonstrated a computational speedup over any classical counterpart, proving that quantum mechanics could evaluate a global property of a function faster th...
