Furthermore, it is not intended to be construed as being bound by any express or implied information presented in the preceding "Background Art" or "Summary of the Invention" or "Detailed Description" sections.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, one or more embodiments are now described with reference to the accompanying drawings, wherein similar reference numerals are used throughout the text to refer to similar components. In the following description, numerous specific details are set forth for purposes of explanation in order to provide a more thorough understanding of one or more embodiments. However, it will be apparent that one or more embodiments may be practiced in various circumstances without these specific details, and the various embodiments may be combined with and referenced to each other without contradiction.

[0055] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0056] As attached Figure 1 As shown, this application embodiment provides a voltage source, including a power supply module 3, a reference source module 1, and a DAC module 2; the reference source module 1 is used to output a first voltage signal; the DAC module 2 is used to receive and process the first voltage signal and output a second voltage signal for driving a quantum processor; the power supply module 3 is used to provide power signals for the reference source module 1 and the DAC module 2 to operate; wherein, the reference source module 1, the DAC module 2, and the power supply module 3 are integrated on different PCB boards.

[0057] A high-precision first voltage signal is output from reference source module 1 and used as a reference signal to DAC module 2. DAC module 2 internally processes the first voltage signal, such as boosting, bucking, or inverting it, to output a second voltage signal to drive the quantum processor. Since the quantum processor integrates a large number of qubits, the number of driving signals required is also large. DAC module 2, with multiple output channels, is used, each capable of outputting a second voltage signal to drive multiple qubits on the quantum processor. The number of DAC modules 2 can be multiple, depending on the number of qubits in the quantum processor. Furthermore, both reference source module 1 and DAC module 2 are active devices, and a power supply module 3 provides the power signal to ensure their normal operation.

[0058] In this embodiment, the reference source module 1, DAC module 2, and power supply module 3 are integrated on different PCBs. The functional modules on different PCBs can be electrically connected via integrated connectors or adapters. This not only avoids signal crosstalk between functional modules but also prevents the power consumption and heat dissipation of the power supply module 3 and reference source module 1 from affecting the performance of the integrated components on the DAC module 2, thus improving the accuracy of the output second voltage signal. Furthermore, integrating the functional modules on different PCBs facilitates the replacement or upgrading of integrated components on one PCB without affecting the functional modules on other PCBs. Additionally, by adding PCBs corresponding to the functional modules, the number of output channels and the number of second voltage signals with different voltage values ​​can be increased, meeting the driving requirements of more quantum processors.

[0059] In the field of electronic technology, the power signal applied to an active device has multiple functions, including ensuring the normal operation of the device and serving as an input signal to the active device. In this embodiment, the power signal belongs to the former category and is used to ensure the normal operation of each functional module. The first voltage signal belongs to the latter category and is transmitted to the DAC module 2 as an input signal. The output channel of the DAC module 2 outputs the second voltage signal.

[0060] Different functional modules have different types and quantities of active devices, and therefore require different power signals for normal operation. (See attached...) Figure 2 As shown in the figure, in one embodiment of this application, the power module 3 includes a plurality of DC-DC units 31, each of which is used to provide a first power signal, a second power signal, or a third power signal; wherein the first power signal, the second power signal, and the third power signal are all voltage signals with different voltage values. The DC-DC unit 31 is also called a DC / DC converter, used to convert DC voltage signals to voltage signals of other voltage values. In this embodiment, the first power signal includes a ±15V voltage signal, the second power signal includes a +5.5V voltage signal, and the third power signal includes a +3.3V voltage signal. Of course, the first power signal, the second power signal, and the third power signal may also include other voltage parameters, specifically determined according to the power signal requirements in the specification of the selected functional module. Furthermore, the appendix... Figure 2 The DAC module 2 described herein operates based on the first and second power signals only as an example. In actual implementation, the power signals required by the instruction manual of the selected DAC module 2 should be determined.

[0061] As attached Figure 3As shown in the embodiment of this application, the reference source module 1 includes a first reference source unit 11. The first reference source unit 11 operates based on the first power supply signal and outputs the first voltage signal. In this embodiment, the accuracy of the second voltage signal output by the voltage source is closely related to the accuracy of the first voltage signal output by the reference source module 1. The first reference source unit 11 is used to output the first voltage signal. The first reference source unit 11 is selected as an ultra-precise reference source, such as the LTZ1000 series reference source, to ensure that a high-precision first voltage signal is output to the DAC module 2, thereby achieving high precision of the second voltage signal output by the DAC module 2.

[0062] As attached Figure 4 As shown in the embodiment of this application, the voltage source further includes a signal processing module 4. The signal processing module 4 is connected to the first reference source unit 11 and is used to boost and invert the first voltage signal, and transmit the processed first voltage signal to the DAC module 2. The signal processing module 4 operates based on the first power signal output by the power supply module 3 and receives the first voltage signal, wherein the first voltage signal is a unidirectional voltage signal, such as a +7V voltage signal. The signal processing module 4 first boosts the +7V voltage signal, resulting in a +10V voltage signal, and then inverts the +10V voltage signal to output a ±10V first voltage signal to the DAC module 2. In addition, the first voltage signal processed by the signal processing module 4 can be transmitted to multiple DAC modules 2, which facilitates the expansion of the output channels of the voltage source by expanding the number of DAC modules 2.

[0063] As attached Figure 5 As shown in the embodiment of this application, the DAC module 2 includes a signal matching unit 21 and a DAC unit 22. The signal matching unit 21 performs matching processing on the first voltage signal output after processing by the signal processing module 4, and transmits the matched first voltage signal to the DAC unit 22. The DAC unit 22 outputs a second voltage signal based on the processed first voltage signal. The signal matching unit 21 operates based on a first power supply signal and is used to match the first voltage signal to ensure the accuracy of the first voltage signal transmitted to the DAC unit 22. The DAC unit 22 operates based on the first power supply signal and the second power supply signal output by the power supply module 3. The DAC unit 22 processes the first voltage signal and outputs a second voltage signal for driving the quantum processor through an output channel.

[0064] As attached Figure 6As shown in the embodiment of this application, the DAC module 2 further includes a first linear voltage regulator unit 23. The first linear voltage regulator unit 23 operates based on the first power supply signal and outputs a third voltage signal; wherein, the third voltage signal is the operating voltage signal of the signal matching unit 21 and the DAC unit 22. In a specific implementation, the first linear voltage regulator unit 23 receives the first power supply signal output by the DCDC unit 31, such as a ±15V voltage signal, performs voltage step-down processing on the voltage signal, and outputs a ±13.5V voltage signal to the signal matching unit 21 and the DAC unit 22 to ensure the normal operation of the signal matching unit 21 and the DAC unit 22.

[0065] As attached Figure 7 As shown, in one embodiment of this application, the DAC module 2 further includes a second linear voltage regulator unit 24. The second linear voltage regulator unit 24 operates based on the second power supply signal and outputs a fourth voltage signal; wherein, the fourth voltage signal is the operating voltage signal of the DAC unit 22. Specifically, the second linear voltage regulator unit 24 receives the second power supply signal output by the DCDC unit 31, such as a +5.5V voltage signal, performs voltage step-down processing on the voltage signal, and outputs a +3.3V voltage signal to the DAC unit 22 to ensure the normal operation of the DAC unit 22.

[0066] In this embodiment, the DAC unit 22 needs to provide voltage signals with multiple voltage values ​​when it is working normally, such as ±13.5V, +5.5V, +3.3V, etc. Moreover, the accuracy requirements of the voltage signals are relatively high. Multiple linear voltage regulator units are used to process the first power supply signal and the second power supply signal, and transmit the processed voltage signals to the DAC unit 22 to ensure the normal operation of the DAC unit 22.

[0067] As attached Figure 8 As shown, in one embodiment of this application, an ADC module 5 located on the same PCB board as the DAC module 2 is further included. The ADC module 5 is used to acquire the second voltage signal output by the DAC module 2. The second voltage signal output by the DAC module 2 is used to drive the quantum processor. The accuracy of the second voltage signal directly affects the driving accuracy of the quantum processor. In order to ensure the accuracy of the output second voltage signal, the ADC module 5 is used to acquire and measure the second voltage signal output by the DAC module 2 to determine whether the accuracy of the second voltage signal meets the requirements.

[0068] As attached Figure 9As shown in the embodiment of this application, the ADC module 5 includes an ADC unit 51, a third linear regulator unit 52, and a second reference source unit 53. The third linear regulator unit 52 operates based on the second power supply signal and outputs a fifth voltage signal and a sixth voltage signal. The fifth voltage signal is the operating voltage signal of the ADC unit 51 and the second reference source unit 53. The sixth voltage signal is the operating voltage signal of the ADC unit 51. The second reference source unit 53 outputs a seventh voltage signal based on the fifth voltage signal. The ADC unit 51 operates based on the fifth voltage signal, the sixth voltage signal, and the seventh voltage signal to acquire the second voltage signal output by the DAC module 2.

[0069] Specifically, the ADC unit 51 requires multiple voltage signals during operation, such as a fifth voltage signal of +5V, a sixth voltage signal of +3.3V, and a seventh voltage signal of +2.5V. The +2.5V voltage requires higher accuracy and is output by the second reference source unit 53. The fifth and sixth voltage signals are provided by the third linear regulator unit 52. Furthermore, the operating voltage of the second reference source unit 53 is also provided by the third linear regulator unit 52. The combined use of the second reference source unit 53 and the third linear regulator unit 52 provides the ADC unit 51 with multiple voltage signals, ensuring the normal operation of the ADC unit 51.

[0070] In the embodiments of this application, the first linear voltage regulator unit 23, the second linear voltage regulator unit 24, and the third linear voltage regulator unit 52 can all be LDOs (Low Dropout Regulators), which have low noise, low quiescent current, simple circuitry, and are easy to integrate. The second reference source unit 53 can be a 2.5V reference source.

[0071] As attached Figure 10As shown, in one embodiment of this application, a central control module 6 located on a PCB board is further included. The central control module 6 operates based on the third power signal and is used to control the DAC module 2 to process the first voltage signal according to the second voltage signal collected by the ADC module 5. The central control module 6 is integrated on a separate PCB board, operates based on the third power signal output by the DCDC unit 31, and is communicatively connected to the ADC module 5 and the DAC module 2. It receives the second voltage signal collected by the ADC module 5 and compares it with the target second voltage signal to be output by the voltage source. It determines whether the second voltage signal output by the DAC module 2 is the same as the target second voltage signal. If they are different, it controls the DAC module 2 to process the first voltage signal, ensuring that the output second voltage signal is the target voltage signal and improving the output accuracy of the voltage source. In addition, placing the central control module 6 and the DAC module 2 on different PCB boards can also avoid interference between the digital signal transmitted on the central control module 6 and the analog signal transmitted on the DAC module 2.

[0072] As attached Figure 11 As shown in the embodiment of this application, the central control module 6 includes a central control unit 61 and a temperature control unit 62. The temperature control unit 62 measures the temperature of the power supply module 3, the reference source module 1, and the DAC module 2, and sends the temperature measurement results to the central control unit 61. The central control unit 61 controls the DAC module 2 to process the first voltage signal based on the second voltage signal collected by the ADC module 5, and controls the temperature of the power supply module 3, the reference source module 1, and the DAC module 2 based on the temperature measurement results. The power supply module 3, the reference source module 1, and the DAC module 2 all include active devices, which generate heat during operation, causing temperature changes in each module and thus affecting the performance of each module. The temperature control unit 62 measures the temperature of each module in real time and sends the temperature measurement results to the central control unit 61, which then controls the temperature control unit 62 to cool down each module. The cooling process can use a fan or other cooling devices, which will not be described in detail in this embodiment.

The chassis 10 contains a plurality of enclosed mounting frames 100, each of which houses one of the aforementioned voltage sources. Specifically, the enclosed mounting frame 100 houses a PCB board integrating various functional modules of the voltage source. The enclosed mounting frame 100 seals part of the PCB board, improving the isolation between the modules and preventing interference.

[0074] Continue as attached Figure 12As shown, in one embodiment of this application, the voltage source device further includes a first fan group 110 and a second fan group 120 located inside the chassis 10; the first fan group 110 is used to dissipate heat inside the chassis; the second fan group 120 is used to dissipate heat separately from the enclosed mounting frame 100 of the power module 3 inside the chassis.

[0075] The first fan assembly 110 is used for overall heat dissipation within the chassis, while the second fan assembly 120 is used for heat dissipation of the PCB board of the integrated power module 3 within the enclosed mounting frame 100. Different heat dissipation methods are selected according to the applicable temperature of different PCB boards, thus adapting to the operating temperature of various PCB boards and ensuring the normal operation of the voltage source.
