Quantum simulation

Definition

Quantum simulation is the use of quantum systems to model and understand complex physical phenomena that are difficult to analyze with classical computers. By leveraging the principles of quantum mechanics, quantum simulation enables researchers to explore and predict the behavior of systems such as superconductors, chemical reactions, and many-body physics. This method is particularly powerful in understanding systems where classical models fail to provide accurate predictions due to their complexity.
