[0002] As one form of a linear Paul trap, a blade-type ion trap has been widely used in ion trap quantum computing due to its advantages such as a stable trapping electric field, strong ion controllability, and multiple light incident angles. A blade-type ion trap usually includes a pair of blade-type radio frequency electrodes and a pair of blade-type direct current electrodes, which are respectively connected to corresponding radio frequency power supplies and direct current power supplies, and then generate an electrostatic field and an oscillating electric field to form a trapping electric field capable of trapping ions. The quality of the trapping electric field is related not only to the stability of the electrical signals applied to the blade-type electrodes but also to the position accuracy of the blade-type electrodes. Since the trapping electric field is jointly constituted by the electric fields generated by multiple blade-type electrodes, if the position accuracy of the electrodes fails to meet specific requirements, the formed trapping electric field is uneven or electric field noise is brought, thereby affecting the ion trapping effect, and even causing ion trapping failure in severe cases.

[0037] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that the purpose of providing these embodiments is to make the principles and spirit of the present invention clearer and more thorough, so that those skilled in the art can better understand and then implement the principles and spirit of the present invention. The exemplary embodiments provided herein are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments herein, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0038] Figure 1 FIG. is a schematic diagram of the installation position of an ion trap blade electrode according to an embodiment of the present invention. In this embodiment, the ion trap includes a set of blade electrode groups for forming an ion confinement channel. Four blade electrodes 20 are respectively installed at predetermined positions on the blade fixing frame 10, and the cutting edges 21 of each blade electrode are arranged opposite to each other in pairs. When an electrical signal is applied to the electrodes, the electric fields generated by multiple electrodes jointly form a confinement electric field. Figure 2 FIG. is a schematic diagram of the structure of a transverse end face of a blade electrode according to an embodiment of the present invention. Figure 3 is Figure 2 a schematic diagram of the structure of the blade electrode shown in the A direction. Combining Figure 2 and Figure 3 , the blade electrode 201 is a thin sheet structure. The two side faces at one end of the cutting edge 2011 intersect at the intersection line 2013, which is the end center line of the cutting edge of the blade electrode 201. Correspondingly, the transverse edges 2012 of the two side faces of the blade electrode intersect at the intersection point 2014.

[0039] Figure 4 FIG. is a schematic diagram of the structure of a transverse end face of a blade electrode according to another embodiment of the present invention. Figure 5 is Figure 4 a schematic diagram of the structure of the blade electrode shown in the B direction. In this embodiment, the blade electrode 202 is a thin sheet structure. The transverse direction at one end of the cutting edge 2021 is trapezoidal, that is, the end of the cutting edge 2021 is a plane 2023, and the plane 2023 intersects with the two side faces 2022 respectively. The longitudinal symmetry axis of the plane 2023 is the end center line of the cutting edge of the blade electrode 202.

[0040] Figure 6 FIG. is a flowchart of a method for adjusting the position of an ion trap blade electrode according to an embodiment of the present invention. In this embodiment, the electrode structure shown in Figure 2 and Figure 3 is taken as an example to illustrate the electrode position adjustment method. The method includes the following steps:

[0041] Step S11, obtain the end center points of the cutting edges of each blade electrode on a transverse end face of the electrode group, construct a first polygon with the end center points of the cutting edges of each blade electrode as vertices, and measure the side lengths of each side of the first polygon.

[0042] Step S12, obtain the end center points of the cutting edges of each blade electrode on the other transverse end face of the electrode group, construct a second polygon with the end center points of the cutting edges of each blade electrode as vertices, and measure the side lengths of each side of the second polygon.

[0043] Step S13, construct a three-dimensional model in a known three-dimensional coordinate system with the first polygon and the second polygon as two transverse end faces, where each edge of the three-dimensional model corresponds to the end center line of the cutting edge of each blade electrode.

[0044] Step S14, calculate the angles between each edge of the three-dimensional model and other edges in the three-dimensional coordinate system, and compare the obtained angles with a threshold value.

[0045] Step S15, when the angle between two edges is greater than or equal to the threshold value, adjust the position of the blade electrode corresponding to the edge.

[0046] Among them, in Step S11 and Step S12, use an electron microscope to align with the electrode group on a transverse end face of the electrode group to obtain an enlarged image as shown in Figure 7 . On the current enlarged image, the intersection point where the horizontal sides of the two side faces of the blade electrode intersect, that is, the intersection point 2014 in Figure 2 is the end center point of the cutting edge of the current blade electrode, so as to obtain the end center points of the four blades, which are the points P1, P2, P3, and P4 shown in Figure 7 respectively. Then construct a polygon 301 with points P1, P2, P3, and P4 as vertices, and measure the side lengths of each side of the polygon 301. Similarly, on the other transverse end face of the electrode group, obtain the end face image by the electron microscope and get the polygon 302 formed by the other end face of the electrode group and the side lengths of each side.

[0047] Among them, Figure 7 the blade electrode shown in the image is in an ideal state. Sometimes, the end of the cutting edge of the blade electrode is damaged, as shown in Figure 8 . At this time, obtain the extension lines of the horizontal sides of the current two side faces, and determine the intersection point P5 of the extension lines of the horizontal sides of the two side faces as the end center point of the cutting edge of the blade electrode.

[0048] When the end of the cutting edge of the blade electrode is in the structures shown in Figure 4 and Figure 5 , the cross-section of the cutting edge is trapezoidal. When obtaining the enlarged image of the transverse end face of the electrode group through the electron microscope, as shown in Figure 9As shown, determine the intersection points P11 and P12 where the horizontal sides of the end face of the blade - type electrode blade tip intersect the horizontal sides of the two sides of the blade, and calculate the distance between the two intersection points. Determine the mid - point P1 of the two intersection points on the straight line where the two intersection points are located, and determine the mid - point P1 as the end - point center of the blade - type electrode blade tip. Obtain the end - point centers of the four blade - type electrode blades in the same way, and then obtain a polygon.

[0049] In step S13, input the polygon 301, polygon 302 and the side lengths of each side into a system with a three - dimensional coordinate system. The system with a three - dimensional coordinate system can be any existing three - dimensional drawing system, such as a CAD three - dimensional drawing system, a Solidworks three - dimensional drawing system, etc. Then, use polygon 301 and polygon 302 as two transverse end faces to construct a three - dimensional model 401. Taking the Solidworks three - dimensional drawing system as an example, using the three - dimensional model creation command in the Solidworks three - dimensional drawing system, set the number of sides and side lengths of the two end faces of the three - dimensional model according to polygon 301 and polygon 302. The Solidworks three - dimensional drawing system generates the three - dimensional model 401 according to the dimensions of the two end faces, as Figure 10 shown. Among them, each edge of the three - dimensional model 401 corresponds to the center line of the end of each blade - type electrode blade tip. For example, Figure 10 the edge P1Q1 and the edge P3Q3 in correspond to Figure 7 the radio - frequency electrode RF1 and the radio - frequency electrode RF2 in, and the edge P2Q2 and the edge P4Q4 in correspond to Figure 7 the DC electrode DC1 and the DC electrode DC2 in.

[0050] In step S14, use the angle - measuring function in the three - dimensional drawing system in the three - dimensional coordinate system to calculate the angle between the four edges. In one embodiment, the technical specification of the blade - type electrode of an ion trap requires that the ideal state of the blade tip in the longitudinal direction is parallel to each other, that is, the angle between the two blade tips is 0 degrees, and the maximum cannot exceed 0.1 degrees. Therefore, taking 0.1 degrees as the threshold, after calculating the angle between the four edges using the angle - measuring function in the three - dimensional drawing system, compare the angle with the threshold. If the angle is greater than or equal to the threshold, the installation position of the corresponding electrode needs to be adjusted. Then execute the Figure 6 shown process to determine whether the adjusted electrode position meets the requirement that the angle is less than the threshold. If not, adjust again until it meets the requirement.

[0051] Among them, when adjusting the electrode position, adjust according to the installation method of the electrode. As Figure 1As shown, mounting holes are provided in the electrode mounting plate, and mounting holes are also provided on the electrode. The electrode is fixed to the electrode mounting plate through connecting members such as bolts. Moreover, for adjustment needs, there is an adjustment margin between the connecting members such as bolts and the mounting holes. Therefore, the position of the electrode cutting edge can be adjusted by loosening the connecting members such as bolts, and then the connecting members such as bolts are tightened after adjustment.

[0052] When the electrode is mounted in other ways, corresponding adjustments are made with reference to the specific structure, which will not be elaborated here.

[0053] Figure 11 FIG. is a schematic block diagram of an ion trap blade electrode included angle measurement system according to an embodiment of the present invention. The ion trap blade electrode included angle measurement system 500 includes a human-computer interaction module 501, an electron microscope module 502, and a three-dimensional model module 503. Among them, the electron microscope module 502 and the three-dimensional model module 503 are respectively coupled to the human-computer interaction module 501. The human-computer interaction module 501 provides an electron microscope interface 5011 for the electron microscope module 502 and a three-dimensional module interface 5012 for the three-dimensional model module 503. Each interface includes a display window and corresponding operation instructions, data input, and other tools. The electron microscope module 502 includes an image acquisition unit 5021 and a side length measurement unit 5022. Correspondingly, the display window in the electron microscope interface 5011 is a measurement plane, and a position input tool, a measurement instruction input tool, etc. are provided. The image acquisition unit 5021 is coupled to the electron microscope, receives the transverse end face image of the blade electrode group sent by the electron microscope, and displays the transverse end face image in the measurement plane in the electron microscope interface 5011, where the transverse end face image of the blade electrode group includes the transverse end face of each blade electrode. When the operator designates the end center point position of each blade electrode cutting edge in this measurement plane through the position input tool, the side length measurement unit 5022 acquires the end center point position of the blade electrode cutting edge, and constructs a polygon with the end center point of each blade electrode cutting edge as the vertex, such as Figure 7 the points and the shape of the polygon shown in. The side length measurement unit 5022 measures the side lengths of each side of the polygon based on each center point position, and sends the polygon and the side lengths of each side to the three-dimensional model module 503.

[0054] The three-dimensional model module 503 includes a three-dimensional model construction unit 5031 and an included angle measurement unit 5032. The three-dimensional model construction unit 5031 is coupled to the side length measurement unit 5022, receives the two polygons measured from the two transverse end face images of the blade electrode group sent by the side length measurement unit 5022, constructs a three-dimensional model in a known three-dimensional coordinate system with the two polygons as the two transverse end faces respectively, and the obtained three-dimensional model is as Figure 10As shown and displayed in the display window provided by the three-dimensional interface 5012. The operator uses the data input tool provided by the three-dimensional interface 5012 to label each edge with its corresponding blade electrode, thereby establishing the corresponding relationship between the edge and the blade electrode. In one embodiment, when the operator uses the tool provided by the three-dimensional interface 5012 to select two edges and input or select the angle measurement instruction, the angle measurement unit 5032 calculates the angle formed by the two selected edges in the three-dimensional coordinate system according to the two edges selected in the instruction, records and displays the angle between the two selected edges. In another embodiment, when the operator uses the tool provided by the three-dimensional interface 5012 to input the instruction to measure the angles between all edges, when the angle measurement unit 5032 receives this instruction, it calculates the angles between all edges, and then records and displays the angles between all edges.

[0055] Optionally, the three-dimensional model module 503 in the ion trap blade electrode angle measurement system 500 further includes an electrode identification unit 5033, as Figure 11 shown by the dashed line in. The blade electrode identification unit 5033 is coupled to the angle measurement unit 5032, and compares the size of the angle with the threshold according to the angle between the edges calculated by the angle measurement unit 5032. When the angle between two edges is greater than or equal to the threshold, determine any one or both of the blade electrodes corresponding to these two edges as the blade electrodes to be adjusted, and display the identification of the blade electrodes to be adjusted as a measurement result in the display window, for example, identify the corresponding edge in the three-dimensional model, or display it in text form in the interface to remind the operator which blade electrode should be adjusted.

[0056] In another optional embodiment, when the blade electrode identification unit 5033 obtains that the angle between two edges is greater than or equal to the threshold, and the angle between another edge and other edges is less than the threshold, determine the blade electrode corresponding to this edge as the reference position for adjustment. Display the identification of the blade electrode providing the reference position for adjustment as a measurement result in the display window, for example, identify the edge corresponding to the electrode to be adjusted in one color in the three-dimensional model, identify the edge corresponding to the electrode as the reference position during adjustment in another color, or display it in text form in the interface to remind the operator of another blade electrode to be referred to when adjusting one blade electrode.

[0057] Based on the foregoing ion trap blade electrode angle measurement system, the present invention also provides an ion trap blade electrode angle measurement method, as Figure 12 shown, including the following steps:

[0058] Step S21: Receive a transverse end face image of the blade electrode group sent by the electron microscope and display it within the measurement plane. Among them, the transverse end face image of the blade electrode group includes the transverse end face of each blade electrode.

[0059] Step S22: Construct a first polygon with the end center points of the cutting edges of each blade electrode input in the current measurement plane as vertices, and measure the side lengths of each side of the first polygon.

[0060] Step S23: Receive another transverse end face image of the blade electrode group sent by the electron microscope and display it within the measurement plane. Among them, the transverse end face image of the blade electrode group includes the transverse end face of each blade electrode.

[0061] Step S24: Construct a second polygon with the end center points of the cutting edges of each blade electrode input in the current measurement plane as vertices, and measure the side lengths of each side of the second polygon.

[0062] Step S25: Construct a 3D model in the known three-dimensional coordinate system with the first polygon and the second polygon as two transverse end faces. Among them, each edge of the 3D model corresponds to the center line of the longitudinal end face of each blade.

[0063] Step S26: Calculate the angle between each edge of the 3D model and other edges in the three-dimensional coordinate system based on the input instruction, and use the angle as the measurement result.

[0064] Optionally, it further includes step S27: Determine the blade electrode to be adjusted.

[0065] Optionally, it further includes step S28: Determine the blade electrode providing the adjustment reference position.

[0066] Among them, in one embodiment, as Figure 13 shown, step S26 includes the following steps:

[0067] Step S261: Take an edge of the current 3D model as the target edge.

[0068] Step S262: Take another edge of the current 3D model as the comparison edge.

[0069] Step S263: Calculate the angle between the target edge and the comparison edge in the three-dimensional coordinate system.

[0070] Step S264: Compare the calculated angle with the threshold value.

[0071] Step S265: Determine whether the calculated included angle is greater than or equal to the threshold value. If the calculated included angle is greater than or equal to the threshold value, then in step S271, mark the electrodes corresponding to the target edge and the comparison edge as electrodes to be adjusted, and then execute step S266. If the obtained included angle is less than the threshold value, then execute step S266.

[0072] Step S266: Determine whether there are still edges to be compared. If so, return to step S262. If not, then execute step S267.

[0073] Step S267: Determine whether there are still edges that have not been used as the target edge. If so, return to step S261. If not, then execute step S268.

[0074] Step S268: Determine whether there is an edge whose included angles with other edges are all less than the threshold value. If so, then execute step S269, and mark the electrode corresponding to it as the blade electrode providing the adjustment reference position. If not, then end.

[0075] Figure 14 It is a schematic connection diagram of an ion trap blade electrode position adjustment device according to an embodiment of the present invention. Among them, the electron microscope communicates with the computing device, and the computing device includes the aforementioned ion trap blade electrode included angle measurement system. The transverse end face of the ion trap blade electrode group is placed within the observation range of the electron microscope, and the operator can obtain a view of the transverse end face of the electrode group with a certain magnification by operating the electron microscope. The electron microscope sends the view of the transverse end face of the electrode group to the ion trap blade electrode included angle measurement system in the computing device and displays it in the measurement plane. Through the operation of the operator, such as specifying the position of the end center point of the blade edge of each blade electrode in the measurement plane and inputting an included angle measurement instruction to obtain the included angle between the blade electrodes of the ion trap, and based on whether the included angle is greater than or equal to the threshold value, it can be determined whether the installation position of the current blade electrode meets the installation accuracy. If not, the operator makes a position adjustment to achieve the installation accuracy.

[0076] When installing a blade electrode on the blade holder 10 of an ion trap, the method and system provided by the present invention can achieve the installation accuracy of the blade electrode. Among them, when the installation of the ion trap electrode fails to meet the accuracy requirements, the formed trapping electric field is uneven or the electric field noise is too large, and the formed ion trapping channel does not meet the ion trapping requirements. When observing the ion state in the trapping channel through the imaging system of the ion trap, it can be known whether the trapping electric field meets the requirements according to the ion position and state. For example, according to the requirements, multiple ions in the trapping channel should be arranged in a straight line with a fixed position. When it is observed through the imaging system that the multiple ions are not arranged on the straight line or no ions are observed, it means that one of the possible reasons is that the position accuracy of the electrode generating the electric field is insufficient. At this time, the method provided by the present invention can be used to adjust the electrode position, thereby improving the uniformity of the electric field and making the ions trapped at the accurate position.

[0077] The present invention also provides an electronic device, including: a processor and a memory storing computer program instructions; when the processor executes the computer program instructions, the included angle measurement method of the present invention is implemented.

In a suitable case, the memory 602 may include a removable or non-removable (or fixed) medium. In a suitable case, the memory 602 may be inside or outside the integrated gateway disaster tolerance device. In a specific embodiment, the memory 602 is a non-volatile solid state memory.
