      abstract = {Technologies for a long-lived 3D multimode microwave  cavity are disclosed. In the illustrative embodiment, a  series of overlapping holes are drilled into a monolithic  block of aluminum forming a cavity. The dimensions of the  cavity formed by the overlapping holes can be made long by  drilling a long series of holes in a row and can be made  high by drilling holes a certain depth into the cavity. If  two dimensions of the cavity are bigger than the diameter  of the holes used to create the cavity, then the cavity can  support electromagnetic waves that cannot propagate through  the holes, leading to a long lifetime in the cavity. A  superconducting qubit or other non-linear element can be  inserted into the cavity, which can controllably interact  with each of several modes of the cavity. In this way, the  modes of the cavity can act as components in a quantum  memory.},
