description Overview

parameter-shift rule

The parameter-shift rule allows approximating the derivative of a quantum circuit's output with respect to its parameters by evaluating it at slightly shifted parameter values and averaging the results.

variational quantum eigensolver

Variational Quantum Eigensolver (VQE) is a hybrid quantum-classical algorithm that utilizes a parameterized quantum circuit to estimate the ground state energy of a given Hamiltonian, iteratively optimizing parameters via classical feedback.
