Unit Disk Graph Maker

This is a GUI written in Python and PySide useful for creating unit disk graphs, specifically intended for use with neutral atom platforms. This project is derivative of work done at MIT iQuHACK 2023 QuERA challenge, and was written with QuERA in mind.

Usage

• Left click the canvas to add an atom
• Left click and drag atoms to move
• Right click to delete

Running

Navigate to ./unitdiskgraphmaker/. Install dependencies and run python unitdiskgraphmaker.py.

Features

Rydgerg Potential Contours

The white blobs around the atoms are a real-time view of the $1/r^6$ Rydberg potential. The area colored white represents the potential at the Rydberg blockade $~6.1\mu\text{m}$. When the Blobs connect, this signifies that the excited states will be highly correlated, and an edge appears on the unit disk graph.

Exporting

The graph can be exported to a CSV file, which maps the canvas onto the $75 \mu \text{m} \times 76\mu \text{m}$ stage of the Aquila processor, scaling the coordinates of the nodes accordingly. The numbers are rounded to the precision accepted by the QuERA API.

Hardware Constraints

The hardware constraints are imposed so that graphs built with this software will be able ro run with no errors. This includes

• restricting the atoms to the $75 \mu\text{m} \times 76\mu\text{m}$ stage of the Aquila processor,
• Imposing the minimum discretized spacing on the $y$ axis of $4\mu\text{m}$
• Preventing atoms from being placed in closer proximity than the resolution of the control lasers, also $4\mu m$.

Depenencies

• Python 3.10.9
• PySide2 5.15.8
• Numpy 1.22.4
