Quantum computing is based on the principles of quantum mechanics, where information is processed using quantum bits, or "qubits." Unlike classical bits, which represent either a 0 or a 1, qubits can exist in multiple states simultaneously due to a property called "superposition." Additionally, qubits can be entangled, meaning the state of one qubit can depend on the state of another, no matter the distance between them. Together, superposition and entanglement allow quantum computers to process massive datasets with high-speed efficiency and accuracy.
