This technology is a platform using metasurface holograms to create optical traps for controlling ultracold atoms with high precision and scalability, applicable in quantum computing and simulation.
Traditional methods for trapping ultracold atoms, like optical lattices using acoustic optical diffractors and spatial light modulators, are limited by large device footprints, high power and cooling requirements, and inflexibility in the control of trap geometries. These limitations restrict the potential for precise control and scalability necessary for advanced quantum technology applications. This technology addresses these issues by providing a method to generate and manipulate ultracold atom traps with unprecedented precision and flexibility, which is crucial for advancing quantum computing and simulation technologies.
This technology employs dielectric, phase-only metasurface holograms to generate and control optical trap arrays for ultracold atoms. Metasurfaces, composed of a 2D array of nanostructured elements, manipulate the amplitude, phase, and polarization of light across the wavefront with subwavelength resolution, enabling the creation of complex, high-density trap geometries. This approach offers significant advantages over traditional methods, including compactness, passive operation, and superior power handling, which facilitate the deployment in field applications and integration into existing setups. Validation testing has demonstrated the technology's capability to create various geometric configurations of trap arrays with high positioning accuracy and uniform intensity, suitable for quantum experiments and applications.
