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: An ionic optical cavity coupling system and method are described. The system includes a first optical cavity, a second optical cavity, and an ion trap system including a direct current electrode pair, a grounding electrode pair, and a radio frequency electrode pair. At least one ion is arranged in the ion trap system. Furthermore, the first optical cavity is used for obtaining a quantum optical signal and sending the quantum optical signal to the ion trap system, so that quantum information of the quantum optical signal is transferred to a single ion in the ion trap system. The second optical cavity is used for obtaining quantum information in the single ion in the ion trap system.
