Artificial intelligence (AI) is a field of research in computer science that refers to the capability of computers to perform tasks typically associated with human intelligence, such as learning, reasoning, problem-solving, perception, and decision-making.
AI encompasses machine learning but is not limited to it. In machine learning, algorithms are not explicitly programmed and learn directly from data or from interacting with an environment like in reinforcement learning.
Examples of AI algorithms that do not use machine learning include sophisticated search algorithms and knowledge-based approaches, sometimes with hardcoded rules. Earlier chess playing software like IBM’s Deep Blue who famously beat Kasparov in 1997 made very limited use of ML, unlike the most recent chess engines.
Quantum AI refers to the use of quantum computing in artificial intelligence and machine learning. Quantum AI thus encompasses quantum machine learning and both terms are sometimes used interchangeably.
