A quantum computer is a type of computer that utilizes principles from quantum mechanics to perform computations. Unlike classical computers, which use bits to represent and process information as either 0 or 1, quantum computers use quantum bits, or qubits, which can exist in a superposition of both 0 and 1 states simultaneously.

How does a quantum computer work?

The way current computers work is that they use electricity to process information. Modern computers only use 2 states. Either no electricity is flowing (0) or there is electricity (1). This might sound complicated but it’s pretty easy. Think of a lamp. If you turn the switch off no current is flowing and the lamp is off. This represents a 0. Vica versa, opening the switch allows current to flow and the lamp turns on. This would be a 1.
