Unlike classical bits that are strictly 0 or 1, a quantum bit (qubit) can exist in a superposition of both states simultaneously. This is described mathematically as a linear combination of basis states, giving quantum computers the ability to explore many solutions in parallel.
Quantum entanglement creates correlations between qubits that have no classical equivalent. Measuring one entangled qubit instantly determines the state of its partner, regardless of distance. This phenomenon is the backbone of quantum teleportation and superdense coding.
Qubits are the fundamental unit of quantum information. Physical implementations include superconducting circuits, trapped ions, photonic systems, and topological qubits. Each platform offers unique trade-offs in coherence time, gate fidelity, and scalability.
