## Features

QNetTI extends [PennyLane](https://pennylane.ai) and the [Quantum Network Variational Optimizer (QNetVO)](https://chitambarlab.github.io/qNetVO/index.html) with variational quantum network inference functionality. The goal of which is to determine the entanglement/correlation structure of source nodes in a quantum network using variational quantum optimization of local measurements. Our methods are compatible with both quantum hardware and simulations thereof.

See our preprint titled "Inferring Quantum Network Topology using Local Measurements" for details [https://arxiv.org/abs/2212.07987](https://arxiv.org/abs/2212.07987).

Please review the [documentation](https://chitambarlab.github.io/qNetTI/index.html) for details regarding this project.  

## Quick Start

Install qNetTI:

```
$ pip install qnetti
```

Install PennyLane:

```
$ pip install pennylane==0.29.1
```

Install QNetVO:

```
$ pip install qnetvo==0.4.2
```

Import packages:

```
import pennylane as qml
import qnetvo
import qnetti
```



Note


For optimal use, QNetTI should be used with the compatible versions of PennyLane and QNetVO. Version compatiblity may change in a future release of QNetTI
