Systems and methods for calibration of compact optical imaging systems that use single atom imaging
Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to calibrate compact optical imaging systems that use single atom imaging. A QIP system includes an optical system including an optical relay that receives a beam of light, a housing, and at least one aperture plate. The optical relay includes at least one lens, at least one mirror to fold the beam of light, and a camera sensor to capture at least one image of the beam of light. The housing accommodates the optical relay and includes a slot mechanically referenced to at least one of the lens(es) and the mirror(s). The aperture plate is receivable in the slot. The aperture plate includes an aperture alignable with an optical axis of the optical relay when the aperture plate is received in the slot.
1 . A method for calibrating an optical system of a quantum information processing (QIP) system comprises:
receiving, by a camera sensor, a first image of a light beam emitted by an ion of a trapped ion chain;
determining, based on the first image, that one or more optical aberrations are present;
positioning a first aperture plate including a first aperture in a first position downstream of a first component of the optical system;
receiving, by the camera sensor, a second image of the light beam emitted by the ion of the trapped ion chain;
repositioning the first component of the optical system based on the second image;
positioning a second aperture plate in a second position downstream of a second component of the optical system, the second aperture plate including a second aperture;
receiving, by the camera sensor, a second image of the light beam emitted by the ion of the trapped ion chain; and
repositioning the second component of the optical system based on the second image.
2 . The method of claim 1 , wherein the first component of the optical system is at least one lens or at least one mirror.
3 . The method of claim 2 , repositioning of the at least one lens corrects aberrations caused at least by decentration X.
4 . The method of claim 2 , wherein repositioning the at least one lens corrects aberrations caused at least by tilt.
5 . The method of claim 1 , wherein the beam of light is emitted by a single ion of a trapped chain of ions of the QIP system.
6 . The method of claim 1 , wherein a diameter of the first aperture at a designated location is substantially the same as the diameter of the beam at the designated location.
7 . The method of claim 1 , wherein the second component is downstream of the first position.
8 . The method of claim 1 , wherein a diameter of the first aperture of the first aperture plate has a first diameter and the second aperture of the second aperture plate has a second diameter different than the first diameter.
