Description

An ion trap ion control experimental system

Technical field

The invention relates to the field of quantum computing technology, and in particular to an ion trap ion manipulation experimental system.

Background technique

Today, ion traps have become the main physical system for realizing quantum computing. The principle of the ion trap itself is actually very simple: it uses the interaction force generated between charges and magnetic fields to restrain charged particles and control their behavior. The two most common types of ion traps are the Penning trap, proposed by Dehmelt, which creates an electric potential through a combination of electric and magnetic fields; and the Paul trap, proposed by Wolfgang Paul (who shared the 1989 Nobel Prize in Physics with Dehmelt), which creates an electric potential through a static and magnetic field. The combination of oscillating electric fields forms an electric potential. Unlike superconducting, light quantum and other routes, ion trap quantum computers need to integrate technologies from many different fields: vacuum, laser and optical systems, radio frequency and microwave technology, and coherent electronic control. Specifically, ion Well quantum computers have the following advantages: longer coherence time, higher fidelity of single-qubit gates and double-qubit gates, more direct state preparation and readout, and high qubit repeatability.

However, in the existing technology, when using a planar ion trap to trap ions, it is necessary to combine the voltage released by multiple electrodes to form a specific electric potential field to confine the charged ions to a specific area. For example, a Chinese patent application discloses an ion trap system and ion manipulation The method, CN112750681B, includes a processing control module, a beam splitting module, a beam control module and an ion trapping module. The ion trapping module includes trapped P ions and electrodes. The electrode is used to trap P ions in M first partitions according to the first control signal generated by the processing control module according to the arrangement of P ions; the beam splitting module is used to trap P ions in M first partitions according to the arrangement of P ions and each The second control signal generated by the maximum number of ions that need to be controlled simultaneously in the second division splits the laser beam to obtain N first beams, divides the N first beams into M second divisions, and divides the M second divisions into The first beams in the partitions are respectively transmitted to M beam control modules; the beam control modules are used to modulate the received first beams and transmit the modulated first beams to corresponding ions in the corresponding first partitions.

Although the above scheme has the above advantages, the disadvantage of the above scheme is that using a planar ion trap to trap ions requires combining the voltage released by multiple electrodes to form a specific electric potential field, thereby confining the charged ions to a specific area, and the planar ion trap system , although it can meet the needs of trapped ions, the traditional planar ion trap system has deficiencies in the electric potential field control level, which leads to a series of experimental errors when the trapped ions are affected by additional environmental influences, and the experimenter cannot adjust The experimental system is used to eliminate additional environmental effects, which causes additional experimental errors to be introduced, resulting in inaccurate experimental results. This has a great impact on the field of quantum precision measurement, so an ion trap ion manipulation experimental system is urgently needed to solve such problems.
