Embodiment 1
[0050] The method embodiment provided in Embodiment 1 of the present application may be executed in a computer terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, figure 1 It is a hardware structural block diagram of a computer terminal for a method for demodulating and analyzing qubit read signals according to an embodiment of the present application. Such as figure 1 As shown, the computer terminal 10 may include one or more ( figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. Optionally, the above-mentioned computer terminal also Transmission means 106 for communication functions as well as input and output devices 108 may be included. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illu...
Embodiment 2
[0085] Embodiment 2 of the present application obtains the target data segment in the form of a computer program. When the program is input [1. Receive and input the original data through the computer terminal; 2. The original equal fraction N1; 3. The first threshold Nk], the program outputs It is [the first processed data];
[0086] Include the following steps:
[0087] Step 1. Receive and input the original data at the program input port through the computer terminal, and set the original equal fraction N1 and the first threshold Nk through manual input, wherein, N1 needs to be greater than Nk, and both are positive integers;
[0088] Step 2. Determine the data to be processed in two ways, one is to perform segmentation processing for the first time, and use the original data as the data to be processed, and the other is to determine the data to be processed through the first processed data;
[0089] Step 3. Determine the fidelity of the data to be processed, which is reco...
Embodiment 3
[0098] The difference from Embodiment 2 is that the first threshold is preferably 1, Figure 4 It is a schematic diagram of a specific execution flow according to Embodiment 3 of the present application.
[0099] The following is a specific and detailed data processing step according to the third embodiment.
[0100] Step1: Obtain the original data, denoted as S, the total length of S is T, input the original equal fraction N1 and the first threshold 1;
[0101] Step2: Determine the data s to be processed in two ways, one is to perform segmentation processing for the first time, and use the original data S as the data s to be processed, and the other is to determine the data to be processed through the first processed data;
[0102] Step3: Perform overall demodulation analysis on the data to be processed to obtain its fidelity, which is recorded as the first fidelity F0;
[0103] Step4: Divide s into N1 equal parts, obtain the fidelity of the neutron data, take the largest f...
