Quantum computers differ from classical computers by processing information using

qubits, or quantum bits, instead of classical bits. Quantum bits can exist in multiple states simultaneously due to a property called superposition, allowing quantum computers to perform multiple calculations simultaneously. Additionally, quantum computers use quantum gates to manipulate qubits, which allows for complex quantum algorithms to be executed. Classical computers, on the other hand, process information using classical bits that can only exist in one of two states: 0 or 1. They use classical logic gates to perform calculations.
