Description

technical field [0001] The invention belongs to the technical field of quantum computing, in particular to a distributed ion trap system. Background technique [0002] In the field of quantum computing, the ion trap technology based on trapped ions is the mainstream technology for force calculation. It uses ions cooled to the ground state as qubits, and the qubits are manipulated and read by laser. In order to improve the stability of ion trapping, Prolonging the coherence time of qubits often requires placing ion traps in ultra-high vacuum chambers. In order to further reduce the collision of gas molecules with trapped ions, the use of ultra-low temperature technology to cool ion traps to the temperature region of liquid helium has been applied in the industry. On the one hand, the ion trap in the liquid helium temperature zone can further increase the vacuum degree of the vacuum chamber and reduce the residual gas molecules; Fidelity of logic gates.

AI Technical Summary

Problems solved by technology

[0003] The quantum computing system using ion trap technology has the problem of large-scale difficulty, which is mainly reflected in: 1. The number of trapped ions in a single ion trap is limited, generally less than 100, so the number of qubits in a single ion trap is not many

2. After the number of trapped ions in the ion trap increases, the control complexity of the ion trap increases, the stability of ion trapping decreases, and the error rate of the system increases

3. The trapped ions of the linear ion trap are linearly arranged, and the realization of the double quantum logic gate can only depend on the adjacent ions. It is relatively difficult to realize the double quantum logic gate of any two ions.

[0005] Therefore, there is an urgent need for a distributed ion trap system to solve the problem of large-scale difficulty in the above-mentioned quantum computing system using ion trap technology
