Universal Quantum Devices Logic-16 unit is designed to analyze photon detection signals from up to 16 input sources simultaneously.
The Logic-16 unit can be used for multi-photon correlation counting and for time-resolved signal analysis. It operates in two distinct modes one for coincidence counting mode and one for time-tagging.
What is Coincidence Counting?
Coincidence counting is the simultaneous detection of two particles, typically photons within tiny fractions of a second, down to picoseconds (0−12 or trillionths of a second), of each other. By detecting the coincidental arrival of two particles it can be inferred that the particles were emitted simultaneously from the same source.
What is Time Tagging?
Time tagging is the precise measurement of the arrival of electrical signals within tiny fractions of a second, down to picoseconds (0−12 or trillionths of a second), of each other. A typical scientific application would be to measure the arrival of single photons using an array of photon detectors.
