NuCrypt RCS Remote Correlation System

Featurette

• Count detection events on up to four local and four remote detectors at 1.25 GHz sampling rates
• Programmable delays and multiple clock domains to account for fiber delay
• Four programmable outputs that are Boolean functions (AND, OR, XOR, NOT, any combinations thereof) of the detector outputs (1.25 GHz update); e.g. the raw detector binary output on the individual detectors or an indication of any particular correlation being detected
• Optional DWDM optical link connects two CPDS-2000's; correlations
• Large memory for storing raw data for off-line processing (~4 Terabits typical storage, can be synchronized to an electrical trigger or received signal from optical channel)

Applications

• Measure entangled light distributed over different fiber lengths
• Quantum key distribution (QKD)
• Quantum feed-forward processing

Descriptions

The NuCrypt Remote Correlation System (RCS) is a highly efficient and user-friendly solution specifically designed to process and store single photon detections. With its wide range of features, the RCS offers a seamless experience in connecting distant single photon detectors, accurately counting and correlating the resulting data, and securely storing it for future analysis.

One of the standout advantages of the RCS is its remarkable ability to account for clock drift and delay caused by channels propagating over different fibers. By effortlessly correlating up to four local and four remote channels, the RCS provides a comprehensive solution that caters to all your correlation needs.

Moreover, the RCS goes above and beyond by offering an optional optical-communications (OC) channel. This innovative feature allows the connection of two RCS systems over optical fiber, transforming them into a single distributed system. This integration enhances the overall capabilities and flexibility of the RCS, making it an invaluable asset for any research or experimental setup.

The RCS is fully compatible with both digital and analog signals from single photon detectors. For the latter, it even includes a thresholding option (T) that digitizes the analog signals directly. This cutting-edge feature comes with programmable threshold and phase settings, ensuring precise and customizable signal processing tailored to your specific requirements.

With the NuCrypt RCS, effortlessly connecting, processing, and storing single photon detections has never been easier. Experience the convenience, advanced features, and unparalleled flexibility that the RCS brings to your scientific endeavors. Trust NuCrypt RCS to streamline your research and unlock new possibilities in the field of single photon detection.
