Richard Feynman once famously said, "I think I can safely say that nobody understands quantum mechanics." Today, most of the artefacts of what we consider to be a technologically advanced world only exist thanks to quantum mechanics. Yet, its strangeness is both inexplicable and inescapable. Things can be in many states at once (superposition), objects can instantaneously affect each other or we can even teleport their state (entanglement), objects can behave as both particles and waves (wave-particle duality) and probabilities appear to be built into the very fabric of reality. In this talk, we will learn how to take advantage of these bizarre concepts of quantum mechanics to build quantum programs in Q# and Azure Quantum using computation theory fundamentally different from what we know from regular computers.
