Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The present invention provides a multi-chassis feedback result control trigger synchronization method, as shown in Figure 1, comprising the following steps:

S101. Select a rubidium atomic clock as the reference clock of each PXIE chassis;

S102. Receive the quantum chip measurement result sampled by the AD sampling card in any chassis, and feed it back to the timing slot cascade control board of the corresponding chassis;

In practical applications, the cascade control board can be selected as the FPGA cascade control board; the cascade control board corresponding to the feedback result received in this step can be used as the main cascade control board;

S103. According to the count of the rubidium atomic clock, the timing slot cascade control board that has received the feedback result sends the feedback result to the timing slot cascade control board externally connected to the chassis in the form of a differential pair, and generates an enabling synchronization signal;

It can be understood that the cascading control board realizes the interconnection and communication of multiple chassis externally through the above steps; the multi-PXIE chassis communicates with each other through a pair of external differential signals of the timing slot board cascading control board; the timing slot of the external connection chassis is cascaded The control board can be used as a slave cascade control board; the master cascade control board can send the received feedback results to the slave cascade control board;

S104, according to the feedback result, the count of the rubidium atomic clock and the enabling synchronization signal, control the timing slot of each chassis to cascade the control boards to send the trigger signal at the same time;

It should be noted that the timing slot cascade control board that receives the feedback result can control the trigger signal in the same chassis to send out according to the feedback result; the timing slot control board of other chassis controls its own chassis according to the feedback result after receiving the feedback result. It can send out the trigger signal of the corresponding channel, and finally ensure that the trigger signal of each chassis is sent out at the same time.

In the above-mentioned multi-chassis feedback result control trigger synchronization method provided by the embodiment of the present invention, used in a multi-PXIE chassis quantum measurement and control system, firstly, a high-precision rubidium atomic clock is selected as a reference source, and a reference clock is provided for each PXIE chassis, and then a high-precision rubidium atomic clock is selected as the reference source. The AD sampling card samples the quantum chip measurement results and feeds them back to the timing slot cascading control board, communicates with each other through a pair of external differential signals of the timing slot board and generates an enabling synchronization signal, and finally controls the same chassis and the cascaded chassis to send triggers at the same time. In this way, the trigger signal of the feedback result output in the multi-chassis quantum measurement and control system is synchronized, that is, the excitation waveform can be fed back to the signal source according to the feedback result and the excitation waveform can be sent, which can be applied to the environment where the multi-chassis trigger signal requires synchronization.

In specific implementation, in the above-mentioned multi-chassis feedback result control trigger synchronization method provided by the embodiment of the present invention, step S101 selects a rubidium atomic clock as the reference clock of each PXIE chassis, which may specifically include: using the rubidium atomic clock to generate a first clock and a frequency greater than The second clock of the first clock; the second clock starts to cycle counting according to the rising edge of the first clock.

Specifically, the rubidium atomic clock is used to generate two clocks with a large frequency difference (for example, the fast clock is 250MHz, and the slow clock is 5MHz). The fast clock starts to count according to the rising edge of the slow clock. For example, 250M and 5M, each count is 50 The 250M cycle slow clock reaches a rising edge. Because the rubidium atomic clock is used as the reference, the fast and slow clocks of different chassis are completely synchronized. It should be noted that the main cascade control board and the slave cascade control board take a 1-meter-long SATA cable as an example to test the delay from sending to receiving is 7 fast clock (250MHz) cycles.

In specific implementation, in the above-mentioned multi-chassis feedback result control trigger synchronization method provided by the embodiment of the present invention, after performing step S104 to send the trigger signal, the method may further include: connecting the trigger signal to the AWG board of the corresponding slot in the chassis. Trigger input, control each AWG board to send the excitation signal to stimulate the quantum chip to work at the same time. In this way, the timing slot cascading control board sends trigger signals to the AWG boards controlled by the feedback results in the same PXIE chassis and the AWG boards controlled by the feedback results in the same PXIE chassis according to the feedback results, so that the AWG boards in different chassis send control signals at the same time. The excitation signal for the quantum chip to work.

In specific implementation, in the above-mentioned multi-chassis feedback result control trigger synchronization method provided by the embodiment of the present invention, the multi-chassis pair cascades the signals of the control boards PXI_STAR1 to 16 through the timing slots of the chassis as trigger signals. That is to say, according to the feedback result, any PXI_STAR1-16 trigger signal synchronization in multiple chassis can be realized arbitrarily.

In specific implementation, in the above-mentioned multi-chassis feedback result control trigger synchronization method provided by the embodiment of the present invention, as shown in FIG. 2 and FIG. 3 , the external cascade ports between each level of cascade control boards are connected through SATA physical lines. ; The AD sampling card communicates through the PXIe_DSTARC signal line on the backplane of the chassis; the rubidium atomic clock is connected to the control board at each level; the output signal of the AWG board of each chassis is connected to the external oscilloscope.

The above-mentioned multi-chassis feedback result control trigger synchronization method provided by the embodiment of the present invention is described below with a specific example:

Step 1. Taking the frequency of the second clock as 250MHZ and the frequency of the first clock as 5MHZ as an example, div_cnt is the count of the first clock sampled by the second clock, and the cycle count starts from the rising edge of the first clock, then div_cnt cycles from 1 to 50 ;

Step 2: Receive the feedback result sent from the AD sampling card, and determine the AWG board that needs to be triggered in the current chassis according to the feedback result, and the AWG board that needs to be triggered in the chassis from the cascaded control board;

Step 3. The chassis with the AD sampling card receives the feedback result and sends the feedback result sent from the AD sampling card to the slave cascade control board when div_cnt is 3 and generates an enable synchronization signal;

Step 4. After verification, the slave cascading control board has a delay of 7 clock cycles to receive the feedback result sent by the main cascading control board and generate an enabling synchronization signal at the same time;

Step 5: According to the feedback result of the transmission, div_cnt is 1 and the three signals of the enable synchronization signal jointly determine the output of the trigger signal.

Because the generation of the enable synchronization signal and the sending of the feedback result are generated when the div_cnt is 3, the transmission path has a delay of 7 clock cycles, and the feedback result is received from the cascade control board when the div_cnt is 10 to generate the enable signal, while The trigger signal is generated when the div_cnt is 1 and the enable signal is combined, so the trigger signal can be generated only after the div_cnt is added to 50 and cleared to 1, so this can ensure the synchronization of the trigger signals output by the feedback results of multiple chassis.

And because the delay of receiving data on the synchronous interface is 7 clock cycles, the first one is when div_cnt is 3, then theoretically the second-level chassis receives the feedback result that div_cnt is 10, and the third-level chassis div_cnt is 17, so theoretically Up to 6 levels of chassis can be serialized to ensure complete synchronization of trigger signals.

It should be noted that, before the present invention executes the above-mentioned multi-chassis feedback result control trigger synchronization method, taking FIG. 3 as an example, two PXIE chassis can be prepared, and multiple (such as two) AWG boards are inserted into the first PXIE chassis. , an AD sampling board and a cascade control board, multiple (such as three) AWG boards and a cascade control board are inserted into the second PXIE chassis; the synchronization interfaces of the two cascade control boards pass through SATA The physical lines are docked; the external rubidium atomic clock is connected to the control board of each level; the output signals of the AWG board of the two chassis are connected to the external oscilloscope. During the execution, power on the two chassis and the rubidium atomic clock, and after the rubidium atomic clock lock signal is turned on, control the AD sampling card to send the measurement data of the analog quantum chip; according to the measurement data sent by the analog quantum chip, you can view the two chassis The AWG output signal channel changes according to the analog feedback data.
