Quantum simulations

Definition

Quantum simulations are computational methods that use quantum systems to model and analyze complex physical systems and processes. They take advantage of quantum mechanics to provide insights into phenomena that are difficult to study using classical approaches, particularly in areas like materials science, chemistry, and quantum computing. By utilizing quantum probability distributions, these simulations can predict outcomes and behaviors with greater accuracy, especially when forecasting future states of a system.
