The feasibility of a fully miniaturized magneto-optical trap for portable ultracold quantum technology

摘要: Experiments using laser cooled atoms and ions show real promise for practical applications in quantum-enhanced metrology, timing, navigation, sensing as well exotic roles quantum computing, networking, simulation. The heart of many these experiments has been translated to microfabricated platforms known atom chips whose construction readily lend themselves integration with larger systems future mass production. To truly make the jump from laboratory demonstrations practical, rugged devices, complex surrounding infrastructure (including vacuum systems, optics, lasers) also needs be miniaturized integrated. In this paper we explore feasibility applying approach Magneto-Optical Trap; incorporating system, source optical geometry into a permanently sealed micro-litre system capable maintaining 10-10 mbar more than 1000 days operation passive pumping alone. We demonstrate such an engineering challenge is achievable recent advances semiconductor microfabrication techniques materials.
