Question: How is a qubit in quantum computing different from a regular bit in classical computing?

A qubit is the quantum equivalent of a bit in traditional computing. Whereas a bit can represent a 0 or 1, a qubit can represent both values simultaneously. This is known as "superposition" and allows for computing power and solutions that are unavailable with traditional computing. A qubit can also represent a third value at the same time, which is known as entanglement. With traditional computing, two bits need to be used to store two bits of data, which requires double the memory and processing power. That's why quantum computing is able to achieve great speed improvements in some cases. Additionally, qubits allow for complex calculations that would take an impractical amount of time on a classical computer.
