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

lattice chip lattice 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 Ám 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.
