Quantum Bits (Qubits)

Quantum bits, or qubits, are the fundamental units of information in quantum computing. Unlike classical bits, which can be either 0 or 1, qubits can exist in a state of 0, 1, or both at the same time, thanks to a property called superposition. This allows qubits to perform multiple calculations simultaneously, greatly increasing computational power. Additionally, qubits can be entangled, meaning the state of one qubit can depend on the state of another, no matter the distance between them. These unique properties enable quantum computers to solve complex problems more efficiently than traditional computers.
