US Patent:

20210319973, Oct 14, 2021

Filed:

May 3, 2021

Appl. No.:

17/306301

Inventors:

- College Park MD, US
Guido PAGANO - Washington DC, US
Paul W. HESS - Middlebury VT, US
Harvey B. KAPLAN - College Park MD, US
Wen Lin TAN - College Park MD, US
Philip J. RICHERME - Bloomington IN, US

International Classification:

H01J 37/08
H01J 37/18

Abstract:

The disclosure describes various aspects of a cryogenic trapped-ion system. In an aspect, a method is described that includes bringing a chain of ions in a trap at a cryogenic temperature, the trap being a micro-fabricated trap, and performing quantum computations, simulations, or both using the chain of ions in the trap at the cryogenic temperature. In another aspect, a method is described that includes establishing a zig-zag ion chain in the cryogenic trapped-ion system, detecting a change in a configuration of the zig-zag ion chain, and determining a measurement of the pressure based on the detection in the change in configuration. In another aspect, a method is described that includes measuring a low frequency vibration, generating a control signal based on the measurement to adjust one or more optical components, and controlling the one or more optical components using the control signal.
