Partner Center. However, there may also be plenty of situations where classical computers will still outperform quantum ones. Retrieved 16 November And because quantum computers would be able to analyse virtually all of the relevant data at once, they are likely to generate predictions that are much more accurate than current weather forecasts. The adiabatic theorem states that if the evolution is slow enough the system will stay in its ground state at all times through the process. Quantum supremacy is a term coined by John Preskill referring to the engineering feat of demonstrating that a programmable quantum device can solve a problem beyond the capabilities of state-of-the-art classical computers. A choice of gate family that enables this construction is known as a universal gate set , since a computer that can run such circuits is a universal quantum computer. Ignacio; Lukin, Mikhail D. However, any measurement can be deferred to the end of quantum computation, though this deferment may come at a computational cost, so most quantum circuits depict a network consisting only of quantum logic gates and no measurements. An Introduction to Quantum Computing.
