A computational system that operates on the subatomic level. The rules and algorithmic structure are based on quantum mechanics, such as superposition. Through the logic of superposition, a quantum bit or qubit occupies more than one state at the same time until a measurement is made to deliver a result. Each qubit can stand for one node, one artificial neuron in a neural network. In regular computing, eight bits of standard computing power has 256 combinations, but only one can be used at a time, whereas eight qubits would be able to store —and process— all 256 combinations at once.

This has significant advantages in performing highly complex operations and solving complicated optimization problems at extreme speeds. Quantum computers could be particularly useful for advanced climate modeling and optimization of mobility systems.
