1Loss of time
If waveform data is transmitted without compression through multiple modules in control and measurement software and electronics system, then data transmission is straightforward and reliable, but time consumption increases significantly due to multiple iterations required for qubit measurement experiments
Solution Approach 1:
The patent applies preliminary action by compressing the waveform data before transmission and circulation through the multiple modules. The control and measurement software performs compression on the waveform data in advance, so that when the data needs to be circulated multiple times for qubit measurement experiments, the transmission time for each circulation is reduced, thereby solving the time consumption problem without adding complex processing during the actual measurement iterations
2Productivity
If waveform data is compressed and transmitted to electronics system, then transmission time is reduced, but additional processing steps are introduced
Solution Approach 1:
The patent applies copying by creating a compressed representation of the original waveform data. Instead of transmitting the full-resolution waveform data through multiple modules, the system creates a compressed copy that contains the essential information needed for qubit measurement. This compressed copy is then transmitted and processed, significantly reducing transmission time while the decompression process reconstructs the necessary data for measurement operations
