description Overview

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.

quantum phase estimation

Quantum Phase Estimation is a quantum computing algorithm designed to precisely calculate the eigenvalues of unitary operators. It utilizes quantum superposition and interference patterns to achieve exponentially higher accuracy compared to classical methods for eigenvalue determination. This technique is particularly valuable for applications in quantum simulations, materials science, and fundame...
