Introducing the Second Generation miniMOT V2

miniMOT V2

Infleqtion miniMOT V2

Achieve a live MOT within hours rather than months

Introducing the miniMOT V2, a unique, compact, off-the-shelf trapped atom vacuum system that enables users to effortlessly create and control quantum matter based on rubidium (Rb) or cesium (Cs) atoms.

With an intuitive user interface, the miniMOT V2 provides greater control over critical system parameters, increasing flexibility for cold atom experiments.

The miniMOT V2 eliminates the guesswork and hassle of setting up large and bulky vacuum equipment, allowing you to focus on designing your cold atom experiment or quantum application work to generate results faster.

Upgrade to the miniMOT V2 for an easy-to-use and efficient solution for your quantum matter needs.

“As a lecturer, I like the miniMOT V2 as it allows me to provide Ph.D. students with exposure to a growing and very promising sector of quantum technologies--that is, the fun and excitement of cold atomic physics. The miniMOT V2 is a boon to the Quantum Engineering Centre for Doctoral Training at the University of Bristol, and it will be useful for training many generations of Ph.D. students in the years to come.”

“My lab partner Glingna Wang and I found the miniMOT with the pre-aligned optics breadboard easy to use. We first balanced the laser power and checked for circular polarization with the in-path half-wave and quarter-wave plates. We continued by modulating the laser diode with a microwave frequency source and locking it onto the correct transition. Lastly, we turned on the Rb dispenser, dialed the current in the anti-Helmholtz coils, and watched the cloud of trapped atoms fluoresce before our eyes! (with proper protection, of course).

Seeing the Rb atoms "bounce" by disturbing the trap with an external magnet was fascinating. We did all of this in under 3 hours thanks to our TA Evan Villafranca, lab director Dr. Danyel Cavazos, and the intuitive Infleqtion miniMOT device.

In this experiment, I learned many things: hyperfine structures and atomic/orbital transitions, laser and magnetic confinement, saturated spectroscopy and Doppler crossover peaks, and laser frequency modulation, among others. It is mind-boggling to think these trapped Rb atoms are at temperatures in the order of mK! Super glad I could witness this!”

  • Photonic integrated beam delivery for a rubidium 3D magneto-optical trap

    A UC Santa Barbara team led by Daniel Blumenthal achieved a significant milestone by demonstrating a photonic-integrated MOT (PICMOT) using a photonic chip to deliver laser cooling beams. With Infleqtion's miniMOT, they successfully trapped over 1 million rubidium atoms, cooling them to temperatures below 1 mK. Making the optical components of a magneto-optical trap (MOT) for laser-cooled atoms smaller will help implement these technologies in portable devices.

  • Neophytes Build a MOT

    A Magneto-Optical Trap (MOT) is a wonderful tool for undergraduate research and teaching laboratories that highlights many topics in modern physics. We describe the design decisions and processes that resulted in an operational MOT using the resources and time available at an undergraduate institution. By building many components and purchasing others, we completed the MOT in about two years for approximately $40,000. Neither of us had experience with optical systems before starting work on the project.

  • Investigation of Inertial Sensing Using Electromagnetically Induced Transparency

    Using a miniMOT, two experiments demonstrated a motion-sensing method using a collective state of atoms. One experiment improved the light-dragging effect in an atomic ensemble, allowing for a highly sensitive atom-based velocimeter. The second experiment involved measuring the motion of an atomic ensemble undergoing Bloch oscillation in a periodic potential, with efficient cooling achieved through Raman sideband cooling. These demonstrations could lead to motion sensing development using the collective state of atoms in various materials.

  • Laser Cooling of 85Rb Atoms to the Recoil Temperature Limit

    The authors used a miniMOT to cool a cloud of 85Rb atoms. The miniMOT was created by focusing a laser beam to a waist of approximately 300 µm and using permanent magnets to provide the magnetic field required for trapping the atoms. By optimizing the cooling parameters, the authors were able to cool the atoms to a temperature of 130 µK, with a loading rate of approximately 4.4×10^7 atoms/s. The miniMOT proved to be a useful tool for studying cold atoms in a compact and portable setup.
