Abstract:
Coupling of a neutral atomic ensemble to superconducting circuits via a magnetic
dipole transition forms an interesting hybrid system. Here we present progress towards
trapping cold rubidium atoms within 10 micrometers of a superconducting circuit using a
cryogenically-compatible atom trap and a tunable, high-Q superconducting resonator.
Evanescent fields around an optical nanofiber with 99.95% transmission form an atom
trap suitable for a 15 mK dilution refrigerator. We are developing the hardware and the
tools to monitor the individual components of the system.
Work supported by NSF though the PFC@JQI, the Atomtronics MURI, ONR,
and DARPA.
