TTMU (Time Tagged Measurement Unit) is a high-precision device designed to measure the time difference between signals to ensure the suitability of photons as a quantum source. It serves as a core piece of equipment for advanced experiments including NV center microscopy, Hong-Ou-Mandel interference, fluorescence correlation spectroscopy, fluorescence lifetime analysis, and quantum key distribution. Designed for exceptional precision and scalability, the TTMU seamlessly integrates with other experimental systems through cloud computing, enabling automated scheduling and device synchronization. This integration significantly reduces the need for manual intervention and streamlines research workflows.
