NuCrypt - Quantum System Control Software

Quantum System Control Software

NuCrypt's quantum system control software (QSCS) is designed to make complex quantum measurements easy to perform. In a typical configuration the QSCS graphical user interface (GUI) software controls a polarization analyzer (PA-1000) and a correlated single photon detection system (CPDS-1000 or CPDS-2000) to enable automated quantum state tomography (QST) or two-photon interference (TPI) fringe measurements. The QSCS calculates and plots useful output metrics like state fidelity or TPI visibility. The QSCS also provides a convenient GUI-based control of a NuCrypt EPS-1000 entangled source,; although, any source can be used with the software. The software can perform the initial alignment of bases states (correcting for unknown fiber polarization transformation) using either polarized alignment signals or by monitoring the coincidence counts generated from a polarization entangled source. By aiding with alignment, data taking, and data processing the QSCS makes complex quantum measurements faster, easier, and more reliable. When paired with NuCrypt hardware, the QSCS can perform a QST in <2 s, making possible near real-time measurements.
