# State Aggregation

## Description

The State Aggregation node aggregates all the states developing over time.

## Input

The node has the following input:

• Wave function ($\psi$): It inputs an analytic wave function or a superpositioned state both in a time dependent or independent setting

## Content

The node aggregates all the states evolving over time.

## Example

In the example below, the State Aggregation node inputs a time-evolving state from the Time Evolution node. The output of the State Aggregation node should be connected to the State Evolution Plot to observe the probability density changing over space (1D) and time.
