Descriptions

NuCrypt's Quantum System Control Software (QSCS) is a powerful tool designed to simplify the process of conducting complex quantum measurements. With its intuitive graphical user interface (GUI), the software provides seamless control over a range of quantum measurement devices, including the polarisation analyser (PA-1000) and the correlated single photon detection systems (CPDS-1000 or CPDS-2000). This enables researchers to effortlessly perform automated quantum state tomography (QST) or two-photon interference (TPI) fringe measurements.

One of the key features of the QSCS is its ability to calculate and plot useful output metrics, such as state fidelity or TPI visibility. These metrics provide valuable insights into the performance and accuracy of the quantum measurements being conducted. By presenting this information in a clear and concise manner, the QSCS allows researchers to easily interpret and analyse their data. In addition to its compatibility with NuCrypt's EPS-1000 entangled source, the QSCS can also be used with any other source. The software offers a user-friendly GUI-based control for the entangled source, allowing researchers to perform the initial alignment of base states. This alignment process corrects for unknown fiber polarisation transformation, which can be achieved through the use of polarised alignment signals or by monitoring the coincidence counts generated from a polarisation entangled source.

By streamlining the alignment, data collection, and data processing processes, the QSCS significantly reduces the time and effort required to conduct complex quantum measurements. When used in conjunction with NuCrypt hardware, the QSCS is capable of performing a QST in less than 2 seconds, enabling near real-time measurements. This not only saves valuable research time but also ensures that researchers can obtain accurate and reliable results in a timely manner.

In conclusion, NuCrypt's Quantum System Control Software (QSCS) is a comprehensive and user-friendly tool that simplifies the complexities of quantum measurements. Its intuitive GUI, compatibility with various measurement devices, and ability to calculate useful output metrics make it an invaluable asset for researchers in the field of quantum physics. With the QSCS, researchers can conduct their experiments with ease, confidence, and efficiency, ultimately advancing our understanding of the quantum world.
