Parametric Circuit

Quantum circuits with variable parameters play an important role in some quantum algorithms, especially variational algorithms. QURI Parts treats such circuits in a special way so that such algorithms can be efficiently…

Parametric States and Parametric Estimators

This tutorial aims to introduce parametric states and parametric estimators, which are also important building blocks of variational algorithms.

Gradient Estimators

One of the most important elements of optimization algorithms is computing the gradient of a physical observable with respect to a set of circuit parameters. This tutorial introduces the gradient estimators QURI Parts provides.
