While classical bits can only represent one of two states, qubits can represent a combination of both states simultaneously.
One of the key differences between classical and quantum computing is the concept of quantum superposition . While classical bits can only represent one of two states, qubits can represent a combination of both states simultaneously. This allows quantum computers to explore multiple possibilities at once, leading to the potential for faster and more efficient computation. Additionally, quantum entanglement , another fundamental principle of quantum mechanics, allows qubits to be linked in a way that the state of one qubit can instantly affect the state of another, regardless of the distance between them. This property enables quantum computers to perform highly interconnected calculations, further enhancing their capabilities.
