What is Quantum Computing?

Quantum computing is a type of computation that harnesses the principles of quantum mechanics to solve complex problems. Unlike classical computers that use bits to store information as 0 or 1, quantum computers use qubits. Qubits can exist in a superposition, meaning they can represent 0, 1, or both simultaneously. This capability allows quantum computers to perform calculations that are impossible for classical computers. — DWTS Eliminations: Who Got The Boot?
