Practical quantum training with cold atoms

The Infleqtion's desqtopMOT is a complete cold-atom platform for practical training in quantum physics and quantum technology. The system combines the necessary experimental hardware with a structured curriculum and enables students and users to directly investigate central concepts of modern atomic and quantum physics in the laboratory.

At the center is the generation and characterization of a magneto-optical trap (MOT) with rubidium-87. This makes it possible to perform real experiments in laser cooling and atomic physics without first having to build a complex cold atom laboratory from individual components.

From atomic physics to the magneto-optical trap

The desqtopMOT teaches both theoretical foundations and practical experimental skills. The curriculum provided by Infleqtion covers, among other things:

  • Atomic structure and energy levels
  • Properties and interaction of light
  • Laser operation and beam guidance
  • geometrical optics
  • Vacuum technology
  • Spectroscopy of Rubidium-87
  • Laser cooling and magneto-optical traps
  • Characterization of cold atomic clouds

Advanced experiments also include sub-Doppler cooling, imaging, Faraday rotation, and electromagnetically induced transparency (EIT).

Rubidium-87 MOT under 300 µK

The system operates on the rubidium D2 line at 780,241 nm. For the MOT, 30–50 mW of laser power is provided; the laser frequency can be tuned by ±50 MHz.

With the system, MOT temperatures of below 300 µK be achieved. Students thus not only learn the theory of laser cooling, but also generate and study real ensembles of cold atoms themselves.

Complete laboratory system

The desqtopMOT integrates the essential components required for the experiments into a compact laboratory platform. These include cold-atom hardware, the vacuum system, laser and control technology, and the necessary optics.

The modular and accessible design simultaneously allows users to understand the optical setup, make adjustments, and practically investigate the underlying physical principles.

Curriculum for Quantum Workforce Training

Infleqtion has designed the curriculum for various educational levels—from two- and four-year undergraduate programs to graduate education and continuing education for scientists and engineers.

This makes the desqtopMOT suitable for university internships and teaching laboratories as well as for the practical training and further education of future specialists in the field of quantum technology.

Typical applications

  • University-level quantum physics education
  • Internships in Atomic and Quantum Optics
  • Quantum Workforce Training
  • Laser cooling and MOT experiments
  • Rubidium spectroscopy
  • Cold atom characterization
  • Demonstration of quantum optical phenomena
  • Training of scientists and engineers

Infleqtion's desqtopMOT

The desqtopMOT combines real cold-atom hardware with a structured educational concept, thereby enabling a practical introduction to modern quantum technologies. The platform is particularly suited for institutions that wish to integrate demanding cold-atom experiments into their training without having to develop a complete system themselves.

Soliton supports universities, research institutions, and companies in the configuration and integration of the desqtopMOT as well as in the selection of complementary components for education and research.
