In the field of quantum computation, an ion trap technology based on trapping ions is a mainstream technology for realizing quantum force computation, ions cooled to a ground state are used as qubits, and control and reading of the qubits are performed by laser. In order to further reduce the collision of gas molecules on trapped ions, the use of ultra-low temperature techniques to cool ion traps to liquid helium temperature zones has been used in the industry. The ion trap in the liquid helium temperature region can further improve the vacuum degree of the vacuum cavity and reduce residual gas molecules on the one hand, and can reduce the heating of the ion crystal and improve the duration time of the ion crystal on the other hand, thereby prolonging the quantum bit coherence time and greatly improving the fidelity of the quantum logic gate.

The quantum computing system adopting the ion trap technology has the problem of large scale difficulty, and is mainly embodied in that 1, the number of ions trapped by a single ion trap is limited, generally is less than 100, and therefore the number of quantum bits of the single ion trap is not large. 2.
