[0054] Example 1

[0055] In combination with the above method, the complete technical scheme of the present invention is as follows: figure 2 , 3 shown.

[0056] This program combines the random walk algorithm and the simulated annealing algorithm, and sets the threshold to collect and confirm the data of the valley bottom data of the oscillation waveform of the overall quantum chip test. First, a set of random decimals random1 between 0 and 1 is generated, and a Set a random integer random2, then start random walk, and set the threshold through the simulated annealing algorithm to obtain the bottom data of the oscillation waveform graph of the quantum chip test, the specific method is as follows:

[0057] First generate a set of random decimal numbers random1 between 0 and 1, and a set of random integers random2. Then start the whole process of random walking. The waveform is composed of a set of point sequences with horizontal and vertical coordinates. The oscillating w...

Abstract

The invention discloses a test method of a quantum chip, and belongs to the field of the test of quantum chips. Currently, during the test of the quantum chip, the efficiency of peak and valley searching is extremely low, and the method can hardly be applied to the test of the large-scale integrated quantum chips. According to the test method of the quantum chip, in the test, a peak value or a valley value of an oscillation waveform needs to be found out in an oscillogram for the test, the wave peak or valley is automatically recognized according to obtained data, a position of the peak valueor the valley value is automatically indicated, and the data can be automatically saved; the ideas of a random walk algorithm and a simulated annealing algorithm are combined and applied to the fieldof the test of the quantum chips; during the test of the quantum chip, the oscillation frequency is high, and the waveform is unstable; and an accurate method is required for the corresponding test. According to the scheme, the search and statistics of the peak value or the valley value can be accurately performed through an automation method, the efficiency is high, and the accuracy is high.

Description

technical field [0001] The invention provides a quantum chip testing method, which belongs to the field of quantum chip testing. Background technique [0002] Quantum computers have become a key technology under research because of their ability to deal with mathematical problems more efficiently than ordinary computers, such as accelerating the time to crack RSA keys from hundreds of years to hours. However, the prototypes of quantum computers at this stage have a small number of qubits, and the actual processing speed is not as fast as that of classical computers. In order to solve this problem, people use quantum virtual machines to predict the behavior of quantum computers. This method is usually used to verify the correctness of quantum algorithms or quantum computer behaviors, and to guide the design of quantum algorithms and quantum computers. The quantum virtual machine is a simulation of the product of the unitary transformation matrix representing the quantum logi...
