QBox
NEW
Introduction & Challenge
Add true quantum-optics experiments to the Discovery Line. qBOX uses the same UC2 cubes as the Core kit and supplements them with a green laser, microwave driver and NV-diamond stage, taking learners from ray optics to room-temperature quantum sensing in minutes. Every module that fits inside our injection molded cubes (now v4!) is 3D-printable, replaceable and the complete setup stays around €1 000.
Same platform, next level – extend any Core setup without replacing parts.
Budget-friendly quantum lab – first fully open-source ODMR kit for around €1 000.
Interdisciplinary – physics, biology and data science in one toolbox.
Learn how to code: – the firmware on the Seeed Studio ESP32C3 Xiao is fully open-source (get it here https://youseetoo.github.io/)
Scalable & repairable – print new cubes or swap optics as you iterate.
Community-driven – hundreds of educators and makers share upgrades and code. Forum: http://openuc2.discourse.group/
Digital guidance
A browser-based wizard walks users through alignment, microwave tuning and live data capture. Fluorescence intensity and ODMR spectra stream directly to Python notebooks or CSV, enabling immediate analysis and challenge-based coursework that blends physics, engineering and data science. The firmware for the esp32c3 can be found here https://youseetoo.github.io/
FRAME stands for Fast and Rigid Automated Microscope Engine – a fully automated XYZ scann
Key experiments
| Experiment | What you learn | Typical outcome |
|---|---|---|
| Michelson / Mach–Zehnder interferometer | Path-length sensitivity, coherence, phase | Resolve sub-nanometre displacements |
| Quantum eraser & polarisation | Wave-particle duality, Malus’ law | Restore / suppress interference by selecting polarisation states |
| Optically Detected Magnetic Resonance (ODMR) on NV-diamonds | Spin physics, magnetic-field & temperature sensing | Plot fluorescence dips vs. microwave frequency and quantify local B-field shifts |
ing platform that separates optical pathways from mechanical motion, offering unparalleled flexibility and precision. Easily integrate new optical setups without realignment, capture high-quality images, and experience microscopy like never before.
