The Building Blocks of Quantum AI: Qubits, Algorithms, and Beyond

Qubits are the foundational building blocks of quantum computing, representing a radical departure from classical bits. Unlike a classical bit, which can exist in only one of two definite states—0 or 1—a qubit leverages the principles of quantum mechanics to exist in a superposition of both states simultaneously. This means a single qubit isn’t just a 0 or a 1, but a weighted combination of both
