US Patent:

20220291268, Sep 15, 2022

Filed:

Mar 9, 2022

Appl. No.:

17/690577

Inventors:

- Boulder CO, US
Haoquan Fan - Erie CO, US
Ying-Ju Wang - Boulder CO, US
Eric Magnuson Bottomley - Broomfield CO, US
Steven Michael Hughes - Louisville CO, US

International Classification:

G01R 29/08

Abstract:

An electromagnetic field detector including a vapor cell, an excitation system, and a frequency tuner is described. The vapor cell has a plurality of quantum particles therein. The excitation system excites the quantum particles to a first Rydberg state. The first Rydberg state has a transition to a second Rydberg state at a first frequency. The frequency tuner generates a tunable field in a portion of the vapor cell. The tunable field shifts the first Rydberg state and/or the second Rydberg state such that the transition to the second Rydberg state is at a second frequency different from the first frequency. The detection frequency range for the electromagnetic field detector is continuous and includes the first frequency and the second frequency.

Abstract:

A vacuum cell provides for electric field control within an ultra-high vacuum (UHV) for cold-neutral-atom quantum computing and other quantum applications. Electrode assemblies extend through vacuum cell walls. Prior to cell assembly, contacts are bonded to respective locations on the ambient-facing surfaces of the walls. Trenches are formed in the vacuum-facing surfaces of walls and via holes are formed, extending from trenches through the wall and into the contacts. Plating conductive material into the trenches and via holes forms the electrodes and vias. The electrodes are contained by the trenches and do not extend beyond the trenches so as to avoid interfering with the bonding of components to the vacuum-facing surfaces of the walls. The vias extend into the contacts to ensure good electrical contact. An electric-field controller applies electric potentials to the electrodes (via the contacts) to control electric fields within the vacuum.
