| Summary: | Compared to conventional encryption, quantum cryptography is a more secure method of
transferring information. One well-known use of quantum cryptography is quantum key
distribution (QKD), which employs a no-cloning theorem to make it difficult to completely
replicate an unknowable and unpredictable quantum state.
This project aims to develop a LabVIEW graphical user interface that allows for real-time
monitoring of the driving voltage and measured voltage, while reducing user inputs. The
voltage control system controls the voltage biasing provided by the source measurement unit
(SMU) which modulates the intensity of the pulses sent to the Mach-Zehnder Interferometer
(MZI) chip. With the final data collected, Python will be used to post process the results for
further analysis.
At the end of the study, the effectiveness of the LabVIEW program will be demonstrated by
controlling the voltage level and speeding up the data collection process. |
