[0056] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0057] Reference Figure 1 The structural diagram of the single-channel RF direct output system provided in the embodiment of this specification includes:

[0058] A DAC RF direct output device 103, wherein the DAC RF direct output device 103 has N pins, where N is a positive integer greater than or equal to 2; the N pins have at least two power domains, and the at least two power domains have power-on sequence requirements.

[0059] In an optional embodiment, in the prior art, the quantum measurement and control system is a device for generating high-frequency (4GHz-8GHZ) quantum signals, which is usually implemented based on frequency multiplication or frequency conversion microwave components and traditional DAC devices. During the implementation process, the connection between the traditional DAC device and the microwave component will encounter problems such as barriers, incompatibility and conflict between the devices, resulting in a skewed integration degree of the quantum measurement and control system. The present application adopts a new DAC RF direct output device 103 to implement the quantum measurement and control system. The DAC RF direct output device 103 has built-in quantum information. By controlling the power-on sequence of the pins of the new DAC RF direct output device 103, a high-frequency analog signal carrying quantum information is output as a quantum signal. In this process, the DAC RF direct output device 103 has built-in quantum information, and the RF direct sampling of the DAC RF direct output device 103 is realized by controlling the power-on sequence of the power domain on the pin, which not only obtains the high-frequency quantum signal, but also prevents the DAC RF direct output device 103 from being unable to start due to excessive current in the startup phase, and the DAC RF direct output device 103 is irreversibly damaged. Optionally, the number of power domains is optimally three.

[0060] The first-level power supply module 101 is used to provide first power supply information.

[0061] In an optional embodiment, for a quantum computing measurement and control system, the power supply output of the power supply subsystem in the quantum computing measurement and control system is generally maintained in a stable output state, but for other components in the quantum computing measurement and control system, due to the different working contents of each component, the current, power supply amplitude, etc. provided are also very different. Therefore, in the process of generating a quantum pulse control signal, due to the different working contents, the current, power supply amplitude, etc. provided are also very different. Therefore, the first-level power supply module 101 of this embodiment has multiple independent output channels for providing the first power supply information. The first power supply information includes the power supply amplitude and the working current, wherein the first power supply information is determined by the working voltage and working current of the N pins of the DAC RF direct output device 103.

[0062] Specifically, the first-stage power supply module 101 has multiple output terminals, and the power supply amplitude and operating current of the first power supply information output by each output terminal are different. It should be noted that the power supply amplitude and operating current output by each output terminal are determined based on the operating voltage and operating current of the N pins of the DAC RF direct output device 103. Therefore, the power supply amplitude output by each output terminal will also be the same.

[0063] Optionally, the first-stage power supply module 101 includes a plurality of power supply sub-modules, and the power supply sub-modules are used to process the received voltage signal and output the first power supply information, that is, the power supply sub-module outputs the power supply amplitude and the operating current.

[0064] Specifically, the power supply submodule is a voltage divider regulator, which can provide fault protection such as overvoltage, overcurrent, over-temperature protection, etc. while increasing the output upper limit of the working current. The voltage divider regulator has one output terminal or multiple output terminals. When the voltage divider regulator has multiple output terminals, the power supply amplitudes output by the multiple output terminals can be the same or different, and the working currents output by the multiple output terminals must be kept different to facilitate the RF direct sampling of the DAC RF direct output device 103.

[0065] In an optional embodiment, the output channels of each voltage divider regulator can adopt four-channel parallel output, or dual-channel or three-channel parallel output. The channel output mode of each voltage divider regulator is designed accordingly based on the working voltage and working current of the N pins of the DAC RF direct output device 103.

[0066] Optionally, the first-stage power supply module also includes an inverting regulator connected to an output terminal of one of the power supply submodules, and is used to invert the first power supply information of the output terminal to meet the working voltage and working current requirements of the corresponding pins on the DAC RF direct output device 103. At the same time, the inverting regulator has a built-in fixed or resistor-programmable soft start timer to prevent surge current from being generated when power is turned on. During the shutdown period of the inverting regulator, the input power load is completely disconnected to achieve true shutdown and ensure output stability.

[0067] The control module 104 is used to provide an enable signal for realizing power-on sequence control. The type of the enable signal corresponds to the power-on sequence of the power domain. The control module 104 includes a voltage monitoring device that can accurately monitor the voltage at each location.

[0068] Optionally, each type of enable signal includes different sub-enable signals, and the types of the sub-enable signals are determined according to the types of power supply information that can be accepted by the pins corresponding to each power domain, and the types include digital signals and analog signals.

[0069] In an optional embodiment, the control module 104 provides an enable signal for power-on sequence control, and different types of enable signals respectively control the power-on sequence of the corresponding power domains, so that multiple power domains on the N pins of the DAC RF direct output device 103 are powered on in a power-on sequence, preventing the DAC RF direct output device 103 from being unable to start due to excessive current during the startup phase, and preventing the DAC RF direct output device 103 from being irreversibly damaged, etc. Among them, the enable signal is a signal similar to a trigger signal, which is used to control the functional switches of each regulator.

[0070] The second power supply module 102 is used to provide a power-on signal to the pin of the DAC RF direct output device 103 according to the power-on sequence requirement based on the enable signal and the first power supply information.

[0071] Optionally, the second power supply module 102 includes different sub-modules 1020, and each sub-module 1020 processes at least one of the enable signals and one of the first power supply information to output a power-on signal.

[0072] Optionally, a power-on signal output by each of the submodules 1020 acts on one pin or acts on two pins having the same power domain but the same operating voltage.

[0073] In an optional embodiment, submodule 1020 is a dual-channel regulator, a low-noise, low-dropout regulator, which can reduce inrush current through a soft start function, minimize phase noise and clock jitter, and improve the performance of the DAC RF direct output device 103, soft start timer, etc. Submodule 1020 can also be a complementary metal oxide semiconductor, low-dropout linear regulator, which adopts an advanced proprietary architecture and provides high PSRR (Power supply rejection ratio) and low noise characteristics.

[0074] In an optional embodiment, the number of sub-modules 1020 included in the second power supply module is determined by the number of pins of the DAC RF direct output device 103. It should be noted that each sub-module 1020 does not have one output end, so the number of sub-modules 1020 and the number of pins of the DAC RF direct output device are not in a one-to-one correspondence.

[0075] In an optional embodiment, in order to prevent the DAC RF direct output device 103 from being damaged by high current breakdown, a current limit is set at the output end of each submodule 1020 in the second power supply module 102 to ensure the normal operation of the DAC RF direct output device 103. The current limit is set by the user according to the upper limit of the current that the DAC can withstand and the operating voltage and current of the N pins of the DAC RF direct output device 103.

[0076] In an optional embodiment, the second power supply module 102 is integrated and is composed of a plurality of sub-modules 1020 .

[0077] Optionally, the power-on signal is a digital signal or an analog signal;

[0078] The enable signal corresponding to a power-on action in the power-on sequence includes an enable signal corresponding to a digital signal and an enable signal corresponding to an analog signal.

[0079] In an optional embodiment, the enable signal corresponding to a power-on action in the power-on sequence may be an enable signal corresponding to a digital signal, or may be an enable signal corresponding to an analog signal, or both the enable signal for the digital signal and the enable signal for the analog signal may exist.

[0080] The present application provides an enable signal for realizing power-on sequence control, and the type of the enable signal corresponds one-to-one to the power-on sequence of the power domain; then, based on the enable signal and the first power supply information, a power-on signal is provided to the pin of the DAC RF direct output device 103 according to the power-on sequence requirements so as to realize the DAC RF direct sampling without connecting a microwave component, and after the power-on signal is ready, the DAC RF direct output device outputs a quantum signal that meets the working requirements of the quantum bit, thereby improving the control efficiency of the quantum bit; and at the same time, a high degree of integration of the quantum measurement and control system is achieved.
