We power
versatile
Modular and flexible, our systems interoperate, work together, and apart just as well. Solutions for (almost) every photonic control problem.
simple
No huge downloads, no naff GUIs, open and published interfaces, crystal clear documentation, and personal support.
Powerful
Enough power for the hungriest heaters and lasers, while precise and quiet enough for the most sensitive experiments.
Photonics is Now
You are changing the world. Our controllers can help you develop, test, and deploy the photonic devices of the future.
Taking Qontrol
Since 2016
From quantum
In 2013, the experiments in our Bristol lab outgrew the instruments from well known manufacturers, so to keep building bigger and bigger quantum photonics, we had to develop our own.
To the world
In 2016, we launched the Q8, our first module. Through word-of-mouth, we connected with labs around the world.
To today
In 2024, we are still striving, offering more, and powering more photonics than ever before.

What people are saying…
Alex Sludds
Qontrol’s electronics are the best off-the-shelf system available to enable rapid prototyping of large-scale photonic circuits. They combine precise control with large channel counts and ease of use.
Jianwei Wang
Qontrol’s drivers work perfectly for our quantum photonics and quantum computing experiments. The team has supported us and helped us build a custom system that’s exactly what we needed.
Joaquin Matres
As a hardware engineer, reliable software drivers are essential. Qontrol equipment is not only easily accessible but also works seamlessly in Python. These things have become invaluable for my projects.
