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.

qubit

The basic unit of quantum information, a qubit is a system with two distinguishable basis states conventionally labeled 0 and 1. Unlike a classical bit, its state can be a superposition of those basis states, described by complex amplitudes. These amplitudes determine measurement probabilities, while their relative phase matters when quantum operations cause different contributions to interfere....
