In Quantum Composer, a simulation is assembled from a set of nodes. Any node represents a building block of the simulation with some content, inputs and outputs. This reference is a detailed description of all  the nodes implemented in the tool.

The nodes have been grouped into the following conceptual categories:

Composer Basics

Most common expressions, warnings and controls of the simulation

Quantum Basics
Nodes representing the basic building blocks of a quantum mechanical system

Nodes related to operators

State Analysis
Nodes related to expectation values, variance, fidelities etc.

Linear Algebra
Nodes related to the energy spectrum and eigenvalues of a Hamiltonian, as well as a node to set up an arbitrary linear combination of the eigenstates

Nodes related to defining real and complex numbers

Nodes that provide common visualization tools

GPE Physics
Nodes related to Bose-Einstein Condensates (BECs) governed by the Gross-Pitaevskii-equation

Nodes related to time developed potentials and GRAPE optimization

Nodes including comments, for loop and scope setup
