Variational parameters are adjustable quantities in quantum algorithms that help optimize the performance of quantum circuits, specifically by minimizing a cost function. They are crucial for techniques such as the Quantum Approximate Optimization Algorithm (QAOA), where these parameters are iteratively tuned to find the best solution to a given optimization problem. This tuning process enables the quantum system to explore various states and converge towards an optimal solution more effectively.
congrats on reading the definition of Variational Parameters. now let's actually learn it.
