* '''Quantum Information Theory''' — The branch of science that uses quantum mechanics to process and communicate information.
* '''Qubit (Quantum Bit)''' — The basic unit of quantum information, which can exist in a superposition of 0 and 1.
* '''Superposition''' — The ability of a quantum system to be in multiple states at the same time until it is "Measured."
* '''Entanglement''' — A phenomenon where two particles become "Linked" so that the state of one instantly influences the state of the other, no matter the distance.
* '''Quantum Teleportation''' — Moving the "Information" of a quantum state from one place to another without moving the physical particle.
* '''No-Cloning Theorem''' — The mathematical proof that it is impossible to create a perfect copy of an unknown quantum state.
* '''Quantum Key Distribution (QKD)''' — Using quantum mechanics to share a secret key that "Self-Destructs" if someone tries to listen in.
* '''Bell's Inequality''' — The test that proved entanglement is a real physical phenomenon, not just a mathematical trick.
* '''Decoherence''' — The process where a quantum system "Leaks" its information into the environment, causing it to become a normal, non-quantum bit.
