      abstract = {A millimeter-wave resonator is produced by drilling a  plurality of holes into a piece of metal. Each hole forms  an evanescent tube having a lowest cutoff frequency. The  holes spatially intersect to form a seamless  three-dimensional cavity whose fundamental cavity mode has  a resonant frequency that is less than the cutoff  frequencies of all the evanescent tubes. Below cutoff, the  fundamental cavity mode does not couple to the waveguide  modes, and therefore has a high internal Q. Millimeter  waves can be coupled into any of the tubes to excite an  evanescent mode that couples to the fundamental cavity  mode. The tubes also provide spatial and optical access for  transporting atoms into the cavity, where they can be  trapped while spatially overlapping the fundamental cavity  mode. The piece of metal may be superconducting, allowing  the resonator to be used in a cryogenic environment for  quantum computing and information processing.
