File:QuEra Aquila Magneto-Optical Trap 2.jpg
A studio photograph of a vacuum and optics assembly on an optical breadboard: a stainless-steel vacuum chamber topped by a SAES Getters pump housing, a rectangular glass cell wrapped in copper-wire coils, and black lens mounts that deliver laser light. QuEra Computing (2023) captions it as the magneto-optical trap of its first-generation neutral-atom quantum computer (Aquila). Laser beams plus a magnetic field gradient cool and gather atoms inside the glass cell before they are loaded into optical tweezers as qubits. “QuEra Aquila Magneto-Optical Trap 2” by QuEra Computing, Inc., commons.wikimedia.org/wiki/File:QuEra_Aquila_Magneto-Optical…, CC BY 4.0 (creativecommons.org/licenses/by/4.0/)

A photograph of the magneto-optical trap of QuEra Computing's first-generation neutral-atom quantum computer, credited to QuEra Computing, Inc. (2023). Two square copper coils wrapped in orange Kapton tape surround a small rectangular glass vacuum cell, with a flanged vacuum section, a getter pump, mirrors and fibre-coupled optics around it. A magneto-optical trap uses laser beams and a magnetic field gradient to cool and gather a cloud of atoms, the first step before single atoms are held as qubits. “QuEra Aquila Magneto-Optical Trap” by QuEra Computing, Inc., commons.wikimedia.org/wiki/File:QuEra_Aquila_Magneto-Optical…, CC BY 4.0 (creativecommons.org/licenses/by/4.0/)
File:QuEra Aquila Optical Layout.jpg
Photograph of an optical table under blue-violet light, packed with mirrors in kinematic mounts, lenses, beam-splitter cubes, a fibre launch and enclosed laser housings. Credited to QuEra Computing, Inc. (2023) as the optical table and layout of QuEra's first-generation neutral-atom quantum computer, Aquila. It shows how much free-space optics is needed to deliver and shape the laser beams that trap, move and excite the atoms; the vacuum cell holding the atoms is not visible here. “QuEra Aquila Optical Layout” by QuEra Computing, Inc., commons.wikimedia.org/wiki/File:QuEra_Aquila_Optical_Layout.…, CC BY 4.0 (creativecommons.org/licenses/by/4.0/)
