What if computers were trillions of times faster?

Could the theory of quantum mechanics one day revolutionise commonplace technical devices such as sensors, communication devices and computers? Quantum mechanics is a scientific theory that has revolutionised our understanding of the Universe. In the world of classical physics, a system is always in one particular state (e.g. at rest or in motion) while in the quantum world, a system can be in a superposition of two or more states. Performing a measurement on such a superposition causes it to collapse into a single state. Furthermore, in contrast to the classical world, where a system can be measured without changing it, in the quantum world a measurement can have an impact on the state of the system.
