ARCHITECTURE FOR COUPLING QUANTUM BITS USING LOCALIZED RESONATORS

摘要

A technique relates a superconducting microwave cavity. An array of posts has different heights in the cavity, and the array supports a localized microwave mode. The array of posts includes lower resonant frequency posts and higher resonant frequency posts. The higher resonant frequency posts are arranged around the lower resonant frequency posts. A first plate is opposite a second plate in the cavity. One end of the lower resonant frequency posts is positioned on the second plate so as to be electrically connected to the second plate. Another end of the lower resonant frequency posts in the array is open so as not to form an electrical connection to the first plate. Qubits are connected to the lower resonant frequency posts in the array of posts, such that each of the qubits is physically connected to one or two of the lower resonant frequency posts in the array of posts.

1. A method of configuring a superconducting microwave cavity, the method comprising:
providing an array of posts of different heights, the array of posts each supporting a localized microwave mode, wherein the array of posts includes lower resonant frequency posts and higher resonant frequency posts, the higher resonant frequency posts arranged around the lower resonant frequency posts; configuring a first plate opposite a second plate; positioning one end of the lower resonant frequency posts in the array of posts on the second plate so as to be electrically connected to the second plate; positioning another end of the lower resonant frequency posts in the array of posts to be open so as not to form an electrical connection to the first plate; and connecting qubits to the lower resonant frequency posts in the array of posts, such that each of the qubits is physically connected to one or two of the lower resonant frequency posts in the array of posts.
