[0001] This invention relates to the field of quantum computer technology, and in particular to a phase information extraction method, apparatus, quantum computer, and readable storage medium. Background Technology

[0002] In quantum computers, the quantum chip is the core of the quantum computer's operation. The quantum chip integrates multiple qubits, each of which is driven by a corresponding qubit driving line. In some quantum chips, there are densely packed qubit driving lines, such as XY driving lines. Due to the density of the qubit driving lines, the driving signal applied to each qubit driving line will not only drive the corresponding qubit, but also affect other qubits. This effect is mainly reflected in the amplitude and phase of the qubits.

[0003] When the driving signal of the qubit driving line is at a specific frequency, we only need to know the phase information of the qubit driving line to read the amplitude information of the qubit driving line on the thermal image.

[0045] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention.

[0048] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0049] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0050] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0051] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0052] In some quantum chips, there are densely packed qubit driving lines. When one qubit driving line transmits a driving signal to drive its corresponding qubit, it can cause crosstalk to other surrounding qubits. (Refer to...) Figure 1 As shown, when qubit 3 is driven by qubit driving line 1, the driving signal transmitted by qubit driving line 1 will interfere with qubit 4. This interference is unavoidable, and the interference is mainly manifested in the effects of phase and amplitude. The amplitude can be read from the thermal image based on the phase. In order to ensure that qubit 4 is driven normally by qubit driving line 2, how to extract phase information is an urgent technical problem to be solved. Therefore, a phase information extraction method, device, quantum computer, and storage medium are proposed.

[0053] Reference Figure 2 This is a schematic diagram illustrating the principle of a phase information extraction method provided in an embodiment of this specification. The phase information is the phase information of the driving effect of the driving signal applied to the driving line of other qubits on the target qubit, including:

[0054] S101: Preprocess the received thermal image to obtain a thermal grayscale image.

[0055] Optionally, the preprocessing of the received heat map includes:

[0056] The heat map image is cropped;

[0057] Perform grayscale processing on the cropped thermal image.

[0058] In a preferred embodiment, since the original thermal image of the qubit driving line contains information such as coordinate axes and scales, which have no practical value in extracting phase information, it is necessary to remove the useless information such as coordinate axes and scales. This application crops the received thermal image to remove useless information. Since the original thermal image of the qubit driving line is a color image, to facilitate subsequent processing of the thermal image, the cropped thermal image will also be processed into grayscale, such as... Figure 2As shown, the cropped thermal image retains only black, white, and grayscale. It should be noted that the thermal image is a thermal image with heatmap information generated by the driving signals applied to the target qubit on other qubit driving lines, including phase, amplitude, and the excitation probability of the qubit's 1 state.

[0059] S102: Matrix the heat grayscale image and traverse the matrixed heat grayscale image according to a preset traversal rule.

[0060] Optionally, the matrixing of the thermal grayscale image includes:

[0061] The heat grayscale image is divided into heat grayscale images composed of multiple columns, wherein the heat grayscale images composed of multiple columns are the matrixed heat grayscale images.

[0062] Optionally, the step of traversing the matrixed grayscale image according to a preset traversal rule includes:

[0063] The matrixed grayscale image is traversed sequentially from right to left through all columns.

[0064] In a preferred embodiment, when the thermal grayscale image is as follows: Figure 3 As shown, the phase information extracted from this grayscale image is not realistic. Therefore, we treat the grayscale image as a matrix, dividing it into multiple columns. Then, we iterate through all columns of the matrixed grayscale image from right to left. For example, we... Figure 3 The image is divided into five columns, labeled 1, 2, 3, 4, and 5 respectively. Then, iterating through all columns from right to left yields the following results: a heatmap composed of columns 5, 1, 2, 3, and 4; columns 4, 5, 1, 2, and 3; columns 3, 4, 5, 1, and 2; and columns 2, 3, 4, 5, and 1. Each iteration produces a heatmap. It should be noted that in actual matrix conversion, to facilitate subsequent phase information extraction, the heatmap grayscale image may be divided into more columns. The number of columns is not limited here and can be adjusted adaptively according to the actual situation.

[0065] S103: Divide the heat map obtained from each traversal into equal parts, and determine the image with the highest similarity based on the division results.

[0066] Optionally, the step of dividing the heatmap obtained from each traversal into equal parts and determining the most similar divided image based on the division results includes:

[0067] Each traversal yields a heat map that is divided into equal parts, resulting in a first heat map and a second heat map. The first heat map and the second heat map are in one-to-one correspondence.

[0068] The first equally divided heat image is mirrored to obtain a mirrored equally divided heat image;

[0069] The similarity between the second equally divided heat image and the equally divided mirror image corresponding to the first equally divided heat image is compared to obtain the two sets of equally divided images with the highest similarity.

[0070] Optionally, the step of equally dividing each of the traversed heat images, and determining the image with the highest similarity based on the equally divided results, further includes:

[0071] Each traversal yields a heat map that is divided into equal parts, resulting in a first heat map and a second heat map. The first heat map and the second heat map are in one-to-one correspondence.

[0072] The second equally divided heat image is mirrored to obtain a mirrored equally divided heat image;

[0073] The similarity between the first and second equally divided heat images and their corresponding equally divided mirror images is compared to obtain the two sets of equally divided images with the highest similarity.

[0074] In a preferred embodiment, to ensure the accuracy of subsequent phase information extraction, it is necessary to find the most suitable traversal heat map for extracting the phase information of the driving influence of the qubit driving line. To this end, the traversal heat map obtained from each traversal needs to be equally divided. That is, after each traversal, it is divided and processed once, mirrored once, and the similarity is calculated. After each division, a first equal-division heat map and a second equal-division heat map are obtained. Then, the first equal-division heat map is mirrored to obtain a mirrored equal-division heat map. Next, the similarity between the second equal-division heat map and the mirrored equal-division heat map corresponding to the first equal-division heat map is compared to obtain the two sets of equal-division images with the highest similarity. The traversal heat maps corresponding to these two sets of equal-division images are the desired images. Figure 4 , Figure 5 As shown, the two images have the highest similarity after being bisected and mirrored. Therefore, these two traversed heat maps are the most suitable for extracting phase information. It should be noted that when performing mirroring, only one of the first and second bisected heat maps needs to be mirrored; it is not limited to mirroring only the first bisected heat map.

[0075] In a preferred embodiment, the above-described method is still used. Figure 3Taking a five-column division as an example, after traversing all columns sequentially from right to left, the traversal heat image obtained from each traversal is divided into equal parts in the middle. Each division results in a first-division heat image and a second-division heat image. Then, the first-division heat image is mirrored, and the similarity between the second-division heat image and the corresponding mirrored image of the first-division heat image is compared. The two sets of equal-division images with the highest similarity are obtained. The traversal heat images corresponding to the two sets of equal-division images with the highest similarity are the traversal heat images composed of columns 4, 5, 1, 2, and 3, and the traversal heat images composed of columns 2, 3, 4, 5, and 1. Through the above method, the most suitable traversal heat image for extracting phase information needs to be found to improve the accuracy of phase information extraction. This facilitates subsequent phase compensation of the driving signal of the target bit driving line based on the phase information, reducing the impact of other bit driving lines driving the corresponding qubits on the target qubit driving line driving the corresponding qubits.

[0076] S104: Extract the phase information of the traversal heat map corresponding to the equally divided image, and determine the target phase information.

[0077] Optionally, extracting the phase information of the traversal heatmap corresponding to the equally divided image and determining the target phase information includes:

[0078] Extract the phase information from the traversal heatmaps corresponding to the two sets of equally divided images with the highest similarity;

[0079] Based on the phase information, the corresponding two-dimensional sub-image is located in the heat image, and the two-dimensional sub-image is fitted using a preset function to obtain the fitting result.

[0080] The target phase information is determined by comparing the fitting results with the expected results.

[0081] In a preferred embodiment, for example, the phase information extracted from the heatmap corresponding to the two sets of equally divided images with the highest similarity is phase A and phase B. The corresponding two-dimensional sub-image can be located in the heatmap using phase A and phase B. Then, the two sub-images are fitted using a preset function to obtain two fitting results. After that, it is determined which of the two fitting results is closest to the expected effect. Assuming that the fitting result of the two-dimensional sub-image corresponding to phase A is closest to the expected effect, then phase A is the target phase information. The corresponding amplitude C is read from the heatmap based on phase A. At this time, the inverse values ​​of phase A and amplitude C, phase-A and amplitude-C, are the phase and amplitude that need to be compensated for when driving the target qubit driving line. Through the above compensation, the influence caused by other bit driving lines driving the corresponding qubits on the target qubit driving line driving the corresponding qubits is reduced. Here, the two-dimensional sub-image is essentially a curve graph, and the preset function can be understood as a formula that can achieve curve fitting, without limiting the specific content of the formula.
