Abstract: Embodiments of this application disclose example optical acquisition, tracking, pointing (ATP) antennas, to implement distribution of an annular Gaussian beam by using an axicon. One example optical ATP antenna includes an input light source, an axicon, and an optical imaging assembly, and central axes of the input light source, the axicon, and the optical imaging assembly coincide. The axicon is configured to: shape a first Gaussian beam emitted by the input light source into a first annular Gaussian beam, and transmit the first annular Gaussian beam to the optical imaging assembly. The optical imaging assembly is configured to: expand the first annular Gaussian beam into a second annular Gaussian beam, and transmit the second annular Gaussian beam to a lower optical path, where a diameter of the second annular Gaussian beam is greater than a diameter of the first annular Gaussian beam.

Abstract: Example ion trap chips and quantum computing methods are described. One example ion trap chip includes a plurality of first ion traps and a plurality of second ion traps. Each first ion trap is configured to store an operation ion, where two adjacent first ion traps form one ion trap group. Each second ion trap corresponds to one ion trap group. Each second ion trap is configured to perform quantum operations of operation ions stored in a corresponding ion trap group, and each second ion trap is located between two first ion traps in a corresponding ion trap group. Operation ions stored in first ion traps in an ion trap group are transported to a corresponding second ion trap along a straight line.

Abstract: A space optical coupling apparatus, including M first couplers, a phase adjustment apparatus, N beam splitters, M second couplers, a coupling apparatus, and a controller. The first coupler receives a beam, and couples the beam to the phase adjustment apparatus. The phase adjustment apparatus includes M phase adjusters, N beam splitters, and N detectors. Each beam splitter is configured to split a received beam into two beams, one sent to a corresponding detector and the other sent to a corresponding phase adjuster. The second coupler receives output light from the coupling apparatus, and transmits the output light into the space. The coupling apparatus is configured to couple a beam onto a single-mode fiber. The controller is configured to control, based on the beam intensity detected by the detector and the beam intensity on the single-mode fiber, the M phase adjusters to adjust the phases of the received beams.
