Last weekend, Max Shirokawa Aalto presented his OpenQuantum project at the 2023 Hackaday Superconference. OpenQuantum’s platform is a fully open-source magneto-optical trap which can be used to collect, control, and manipulate ultracold rubidium atoms.
The design is fully open-source, and includes all the CAD files, machining instructions, electronics schematics, PCB files, firmware, and software necessary to build the apparatus for around $8k, which is significantly cheaper (by two orders of magnitude) than commercial solutions.
In his excellent talk, Max introduced the principle of atomic cooling and trapping using magnetic fields and lasers. He then discussed the 3D-printed laser and system for observing the absorption spectrum of atoms, and touched on the high-vacuum system needed for a fully-operational trap.
Max envisions OpenQuantum to be a platform that can be used for teaching Quantum Mechanics, as well as the basis for developing new quantum technologies. Max is looking for collaborators for his exciting project. You may contact him at: email@example.com
