Technical Field
[0001] The embodiments of the present application relate to the field of computers, and more specifically, to a drive test method and device for a quantum operating system. Background Art
[0002] The quantum gate operation of the qubit requires sending the corresponding driving signal to the qubit in the ultra-low temperature environment. However, because the devices involved in the transmission of the quantum driving signal are all non-ideal devices, when the driving signal is transmitted to the quantum chip close to absolute zero through the transmission line composed of non-ideal devices, the driving waveform is likely to be distorted, resulting in the qubit gate operation failing to achieve the expected goal. At present, the scheme of inputting a known driving signal to drive the qubit to perform a quantum gate operation and then extracting the signal obtained by the operation and comparing it with the quantum gate operation simulation signal of the known input signal is used to determine whether the driving signal is distorted. However, this test method requires complex quantum-level operations and needs to extract signals processed by quantum-level operations that are difficult to extract. The test process is relatively complicated and is prone to misjudgment of the cause of the driving signal distortion due to other factors, such as the working performance of the qubit itself. The low-temperature test efficiency of quantum driving performance is low. Summary of the invention

The signal collector is used to connect to the target quantum chip. The method is applied to the test controller. Figure 2 is a flow chart of a drive test method of a quantum operating system according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:
[0061] Step S202, controlling the signal transmitter to send a target driving signal to the target quantum chip;
[0062] Step S204, collecting the radiation signal generated by the target quantum chip from the target quantum chip by the signal collector to obtain a reference driving signal, wherein the reference driving signal is a driving signal transmitted from the target driving signal to the target quantum chip through the signal transmission link;
[0063] Step S206: testing the quantum driving performance of the quantum operating system according to the signal difference information of the reference driving signal relative to the target driving signal.
[0064] Through the above steps, since a drive test system including a test controller and a signal collector is set up, the test controller is connected to the signal collector, and the quantum operating system to be tested includes: a signal transmitter, a signal transmission link and a target quantum chip, the signal transmitter is connected to the target quantum chip through the signal transmission link, the signal transmitter is used to transmit a quantum drive signal to the target quantum chip, the signal collector is used to connect to the target quantum chip, and the target drive signal is sent to the target quantum chip by controlling the signal transmitter, and the radiation signal generated on the target quantum chip is collected from the target quantum chip by the signal collector, and the target drive signal is transmitted to the target quantum chip through the signal transmission link. The reference drive signal, which is a reference drive signal, is obtained, and the quantum drive of the quantum operating system is tested according to the signal difference information of the reference drive signal relative to the target drive signal. The quantum driving performance of the quantum operating system is improved by using a test controller to control a signal transmitter to transmit a target driving signal, and a signal collector is provided to collect the reference driving signal transmitted to the target quantum chip via a signal transmission link. The quantum driving performance of the quantum operating system is tested according to the difference information between the reference driving signal and the target driving signal. No quantum-level operation is required, which reduces the difficulty of testing the driving signal and eliminates the influence of the quantum chip's own factors on the driving signal test, thereby improving the accuracy of the test. Since no quantum operation is required, there is no need to send a driving signal that is difficult to collect and is suitable for quantum-level operation, thereby reducing the difficulty of collecting the signal reaching the target quantum chip. Therefore, the problem of low-temperature testing efficiency of quantum driving performance can be solved, thereby achieving the effect of improving the low-temperature testing efficiency of quantum driving performance.
[0065] Optionally, in the embodiment of the present application, the signal collector includes but is not limited to a loop antenna, and a signal preliminary processing device such as an attenuator and an amplifier. In the embodiment of the present application, it includes but is not limited to collecting a preliminary radiation signal through a loop antenna, reducing the impurity signal in the preliminary radiation signal by a signal preliminary processing device, amplifying the signal characteristics of the preliminary radiation signal, and obtaining a radiation signal.

Optionally, the signal transmission link includes but is not limited to non-ideal devices such as IQ mixers, amplifiers, filters, attenuators, etc. Optionally, in an embodiment of the present application, the target quantum chip includes but is not limited to one or more quantum bits, and the quantum drive signal in the quantum operating system is used to drive the quantum bits to perform quantum gate operations. Since IQ mixers, amplifiers, filters, attenuators, etc. are all non-ideal devices, the waveform emitted by the signal transmitter will change. Moreover, the test circuit of the superconducting quantum chip spans from room temperature to near absolute zero, and the change in temperature gradient will also cause the microwave pulse to change. Therefore, there is a large waveform distortion between the input waveform of the room temperature AWG and the actual waveform of the superconducting quantum chip that actually reaches the low temperature region, and the waveform needs to be corrected to obtain better test results. The large gap between the actual driving pulse reaching the quantum bit and the expected driving pulse will cause the quantum bit to be affected by some non-preset frequencies and transition to a non-computational state, resulting in the quantum bit's gate operation failing to achieve the predicted target, affecting the fidelity of the quantum gate operation. In order to optimize the waveform and improve the fidelity of the quantum gate operation, the quantum bit is tested at low temperature, and the driving signal reaching the quantum bit at low temperature is corrected through data analysis.

Through the above steps, the quantum drive performance is strictly judged to avoid the impact of inappropriate quantum drive signals on the state of the quantum chip and the waste of quantum operation resources caused by reaching the target quantum chip.

[0078] Optionally, in an embodiment of the present application, including but not limited to the need to place the signal collector within a target position range corresponding to the target quantum chip, and if the target position relationship between the signal collector and the target quantum chip is different within the target position range, the initial radiation signal of the target quantum chip collected by the signal collector is also different, and the initial radiation signal needs to be converted into a target radiation signal based on the target position relationship. The conversion relationship between the target radiation signal and the reference drive signal is determined, and then the reference drive signal can be obtained based on the target radiation signal.

The received signal is transmitted to the digital oscilloscope at room temperature through the SMA terminal to detect the radiation waveform of the bit drive line on the superconducting quantum chip. By simulating the size of the antenna on the PCB board to make its resonant frequency close to the frequency of the superconducting quantum bit drive signal, the signal output by the superconducting quantum bit drive line can be efficiently received. Since the frequencies of superconducting quantum bits and their drive signals are relatively close, usually the difference between neighboring bits is only tens of megahertz, so only one antenna is needed to receive the waveforms corresponding to all bit drive lines on the superconducting quantum chip, and the dilution refrigerator circuit and microwave devices are rarely occupied. Since the current drive waveform distortion on the superconducting quantum chip is mainly caused by impedance mismatch on the line, the test line spans different temperature zones, and the devices on the test line (mixer, attenuator, amplifier, filter), it has little to do with the superconducting quantum bit itself. Therefore, the present application proposes a new detection scheme for quantum bit driving waveform distortion. The signal collector based on the antenna structure directly collects the radiation signal of the driving signal transmitted to the quantum bit to determine the distortion of the driving signal, thereby realizing the judgment and targeted correction of the waveform distortion caused by the test circuit and the devices on the circuit without performing complex tests on the superconducting quantum bits.

[0095] Generate a transmission instruction, wherein the transmission instruction is used to instruct the signal transmitter to transmit the target driving signal to the target quantum chip;
[0096] The transmission instruction is sent to the signal transmitter, wherein the signal transmitter is used to execute the transmission instruction.
[0097] Optionally, in an embodiment of the present application, the generated transmission instruction includes but is not limited to carrying attribute information of the driving signal that needs to be transmitted by the signal transmitter, or carrying quantum bit information of the target quantum bit of the driving signal that needs to be driven. The signal transmitter records the correspondence between the target quantum bit and the target driving signal. The signal transmitter can determine the signal attributes of the driving signal to be transmitted based on the quantum bit information carried in the transmission instruction.
[0098] Through the above steps, a transmission instruction is generated and sent to the signal transmitter to control the signal transmitter to transmit a target driving signal. The signal transmitter can be controlled to transmit a suitable driving test signal, thereby reducing the difficulty of detecting a radiation signal corresponding to the driving signal transmitted to the quantum chip, reducing the use of non-ideal devices in the driving test process, and improving the low-temperature test efficiency of the driving signal.
[0099] As an optional implementation, the generating of the emission instruction includes: generating a first emission instruction, wherein the emission instruction includes the first emission instruction, and the first emission instruction is used to instruct the signal transmitter to transmit a driving signal to the target quantum chip and return a signal attribute of the transmitted driving signal;

[0103] Through the above steps, the signal transmitter is required to transmit a driving signal and at the same time, the signal transmitter is required to return the signal attribute of the transmitted driving signal, without specific requirements on the attribute of the signal transmitted by the signal transmitter. While requiring the signal transmitter to transmit a driving signal and obtain the attribute of the transmitted driving signal, the requirements on the signal transmitter transmitting the signal are reduced, the difficulty of the signal transmitter transmitting the driving signal is reduced, the possibility of failure of the driving signal test due to failure to transmit the signal is reduced, and the test efficiency of the low-temperature test of the driving signal is improved to a certain extent.
[0104] As an optional implementation manner, the generating of the emission instruction includes: generating a reference signal attribute; generating a second emission instruction carrying the reference signal attribute, wherein the second emission instruction is used to instruct the signal transmitter to transmit a driving signal having the reference signal attribute to the target quantum chip;

When the low-temperature test requirements for the drive signal are high, a reference signal attribute that is closer to the specific drive signal attribute used when the quantum bit performs a quantum gate operation is set.
[0107] Through the above steps, the test controller directly sends a transmission instruction that specifies the signal attributes of the driving signal to be transmitted to the signal transmitter, which shortens the interaction process between the test controller and the signal transmitter and improves the low-temperature test efficiency of the driving signal.

[0112] Through the above steps, the quantum driving performance of the quantum operating system is tested by the parameter differences in multiple signal dimensions, and the quantum driving performance of the quantum operating system is comprehensively judged, which improves the rigor of the test of the quantum driving performance, avoids the occurrence of false measurements, and improves the accuracy of the quantum driving performance test.
[0113] As an optional implementation, the test controller includes: one or more signal detectors and a processor, the processor is connected to the one or more signal detectors, the one or more signal detectors are connected to the signal collector, and different signal detectors correspond to different signal parameter dimensions;

[0116] The processor detects the parameter difference between the reference parameter value and the target parameter value in each signal parameter dimension.
[0117] Optionally, in an embodiment of the present application, the processor includes but is not limited to a spectrometer, which is used to analyze the frequency distribution of the driving signal of the quantum bit reaching the quantum chip at low temperature.
[0118] As an optional implementation, the one or more signal detectors include: a digital oscilloscope, and the signal parameter dimensions corresponding to the digital oscilloscope include: a signal waveform dimension and a signal spectrum dimension;
[0119] The step of testing the quantum driving performance of the quantum operating system according to the parameter difference in each signal parameter dimension and the parameter error range corresponding to each signal parameter dimension includes:
[0120] Detecting, by the processor, a waveform relationship between a waveform parameter difference and a waveform parameter error range in the signal waveform dimension, and a spectrum relationship between a spectrum parameter difference and a spectrum parameter error range in the signal spectrum dimension;
[0121] Detecting, by the processor, a signal distortion degree according to the waveform relationship and the frequency spectrum relationship, wherein the signal distortion degree is used to indicate a degree of distortion of the reference drive signal relative to the target drive signal;
[0122] The quantum driving performance of the quantum operating system is determined according to the signal distortion degree.
[0123] Optionally, in an embodiment of the present application, including but not limited to, when it is determined that the quantum driving performance of the quantum operating system is poor based on the signal distortion degree, a digital oscilloscope is used to directly observe the waveform of the driving signal when it reaches the quantum bit at low temperature, the driving signal is corrected based on the observed waveform, and the waveform correction process is observed in real time using a digital oscilloscope.
[0124] Optionally, in an embodiment of the present application, including but not limited to, when it is determined that the quantum driving performance of the quantum operating system is good according to the signal distortion degree, the signal transmitter transmits a driving signal to drive the quantum bit to perform quantum operation, and when a problem occurs during the quantum operation process on the bit, the bit driving signal is observed at any time through a digital oscilloscope.
[0125] As an optional implementation, the present application also provides a method for quickly judging the distortion of the superconducting quantum bit driving pulse waveform using a PCB antenna. Figure 4 is a flow chart of a method for determining the distortion of a superconducting quantum bit driving pulse waveform according to an embodiment of the present application, such as Figure 4As shown, since the superconducting antenna, i.e., the circuit of the signal collector, only receives the signal radiated by the driving line, no signal input is required. Only one attenuator and one amplifier (low temperature or room temperature) are required on the antenna waveform distortion test circuit, and the test circuit itself has little effect on the waveform. After the dilution refrigerator detects the signal of the bit driving line at low temperature, the signal is transmitted to the room temperature oscilloscope for waveform and frequency analysis. Therefore, the cost of the entire test circuit is low, and the dilution refrigerator circuit is less occupied. During the entire test process, the room temperature measurement and control system, i.e., the signal transmitter, sends a waveform through the mixing frequency, attenuator, filter and high-frequency circuit to reach the superconducting quantum bit of the target quantum chip in the temperature zone close to absolute zero. The radiation signal of the superconducting quantum bit driving line is collected by the antenna, and the test signal is sent to the digital storage oscilloscope, i.e., the processor, through the attenuator and room temperature amplifier. The waveform and frequency analysis are performed on the oscilloscope to determine the condition of the drive waveform distortion. When the waveform of the detected bit driving signal on the digital oscilloscope is significantly different from the expected waveform, the input waveform can be corrected and the signal reaching the bit at low temperature can be observed in real time on the oscilloscope, so that the drive waveform of the quantum bit can be corrected in a targeted manner. In order to reduce the interference of adjacent quantum bit driving lines on the antenna collection signal, the measurement and control system only applies a signal to the driving line of one bit at a time during the waveform distortion detection process. The PCB antenna line is only enabled when the chip waveform distortion is detected and corrected or when the chip test fails. After installing enough attenuators to isolate the thermal noise, the performance of the superconducting quantum chip is minimal.
[0126] Through the scheme provided by the present application, the situation that the multiple processing defects of the quantum bits themselves caused by the extremely low yield of superconducting quantum bits will lead to the influence of deviation on the judgment of the drive waveform distortion, and the situation that it is difficult to directly determine the processing state of the quantum bits themselves, the present application does not need to test the quantum state of the superconducting quantum bits, which greatly simplifies the test process. The pulse shape can be observed intuitively by using an oscilloscope without the need to analyze the bit test data to guess the waveform, and even the waveform can be preliminarily checked at room temperature. In addition, the digital storage oscilloscope can intuitively observe the drive signal waveform that reaches the superconducting quantum bit through the drive line at low temperature in real time, and can perform spectrum analysis. When performing waveform correction, the waveform can be observed in real time by an oscilloscope, so as to make targeted corrections to the waveform distortion, thereby improving the optimization efficiency of the waveform.
