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.

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...
