Group Seminar via Zoom: Progress towards chip scale cold atom trapping and remote entanglement
Jin Zhang, The University of Wisconsin-Madison, Madison
Group meeting via video conference, (Zoom)
Thursday, March 10th, 16:00 pm (MEZ)
Due to the Covid-19 pandemic, we are still holding our group seminars and journal clubs via video conference. This procedure enables us to continue our research, enhance discussions and exchange important information.
Laser cooled atoms are important tools for quantum computing, simulation, and communication. However, trapping and manipulating cold atoms requires many optical components which often occupy a large space on the optical table. Have you ever thinking about getting a setup that can plug and run? In this talk, I will present my current progress on getting a dual species magneto-optical trap using chip scale diffraction grating, for both rubidium and cesium atoms. The grating simplifies the optical setup as it requires only a single laser beam compared to a conventional MOT with six beams. I will also show our effort towards entangling two quantum processors with on-chip optics. I discuss and compare different approaches using optical cavities and high NA lenses or mirrors, and how we can boost up the entanglement rate.
