News: 2D lattice of microtraps on a permanent magnetic atom chip

An envisioned future neutral-atom quantum register

Left: electron microscope photograph of our atom chip based on a patterned, 300-nm thick FePt film (magnetized out of plane). Four trapping sites are indicated by dashed ellipses. Right: experimentally obtained absorption image of ultracold clouds of ⁸⁷Rb atoms, trapped about 10 µm from the chip surface. Traps in the center contain approximately 10⁴ atoms each. This lattice is very promising as it can potentially fulfill all the requirements of a scalable and addressable quantum information register.
