Problems solved by technology

However, the ions will gradually heat up during the repeated movement, especially when moving in a 90° turn, the ions will be greatly heated, making the kinetic energy of the ions too high, jumping out of the ion trap and causing ion loss, which greatly reduces the working efficiency of the ion trap system

Abstract

The invention provides an ion trap chip and system, which are suitable for the field of quantum computing. The ion trap chip comprises a plurality of first ion traps used for storing operation ions, wherein two adjacent first ion traps form an ion trap group; second ion traps corresponding to one ion trap group, wherein the second ion traps are used for executing the quantum operation of the operation ions stored in the corresponding ion trap group, and the second ion traps are located between the two first ion traps in the corresponding ion trap group; and the operation ions stored in the first ion trap in the ion trap group are transmitted to the corresponding second ion trap along a straight line. The ion storage region and the quantum operation region in the ion trap chip are separated, and the ion storage region and the corresponding quantum operation region are located on the same straight line, so that turning is not needed in ion transportation, and the efficiency of quantum calculation is greatly improved.

Description

technical field [0001] This application relates to the field of quantum computing, in particular to an ion trap chip and system. Background technique [0002] The ion trap system is considered to be one of the hardware systems most likely to realize a quantum computer. It has many advantages such as high fidelity of quantum gate operation and long coherence time, but there are also problems such as scalability and laser manipulation that are too complex and unstable. At the same time, the current ion trap quantum computing system does not have the ability of parallel quantum operations. [0003] At present, the traditional one-dimensional ion chain can store about 50 ions at room temperature. If a 4k low temperature design is adopted, the number of ions can be increased to 100, but it is almost impossible for this structure to store more than 100 ions at the same time. More importantly, the more ions there are in the one-dimensional chain, the lower the precision of quantum...
