What are qubits and how do they work?

Qubits are the basic units of quantum information, similar to bits in classical computing. Unlike bits, which can be either 0 or 1, qubits can exist in a superposition of both states simultaneously.

What is superposition in the context of qubits?

Superposition allows qubits to represent multiple states at once, enabling quantum computers to process a vast amount of information simultaneously.

How do qubits differ from classical bits?

Classical bits are binary and can only be in one state at a time (0 or 1), while qubits can be in multiple states due to superposition and can also be entangled with other qubits.

What is entanglement and why is it important?

Entanglement is a phenomenon where qubits become interconnected, such that the state of one qubit can depend on the state of another, no matter the distance. This is crucial for quantum computing as it allows for complex computations and faster processing.
