Quantum simulations

Definition

Quantum simulations refer to the use of quantum systems to model and analyze complex phenomena that are difficult to study using classical computers. By harnessing the principles of quantum mechanics, these simulations can provide insights into various fields, such as materials science and molecular chemistry, while also allowing for a deeper understanding of quantum systems themselves. This method leverages quantum states and operations to represent and solve problems that have exponential complexity in classical computing.
