What is the difference between quantum computers and regular computers ?

Quantum computing is a type of computing that uses quantum–mechanical phenomena, such as superposition and entanglement, to perform operations on data. This is different from traditional computing, which uses binary bits (1s and 0s) to represent and process data. Quantum computers use quantum bits, or qubits, which are particles that can exist in multiple states at the same time. This means that instead of representing data as 1s and 0s, qubits can represent 1s, 0s, and both 1s and 0s simultaneously, allowing for a much larger range of possibilities. Quantum computers can also perform calculations much faster than traditional computers, as they can process and analyze multiple pieces of data at once. This means that they can analyze large datasets quickly, enabling them to solve complex problems that traditional computers would take a long time to solve.
