基于钛跃迁边缘传感器的高速、高量子效率的光子数分辨探测器已被开发出来，用于量子信息和量子辐射测量领域的量子传感器。在感兴趣的波长下优化的两种设备在 850 nm 和 1550 nm 处的系统检测效率分别为 81% 和 64%。针对高计数操作而优化的器件的响应速度为 190 ns，相当于超过 1 MHz 的计数速率。
Photon number resolving detectors based on titanium-transition edge sensors with high speed and high quantum efficiency have been developed for quantum sensors in the fields of quantum information and quantum radiometry. The two devices optimized at wavelengths of interest showed 81% and 64% system detection efficiencies at 850 nm and 1550 nm, respectively. The response speed of the device optimized for a high counting operation is 190 ns, which corresponds to a counting rate over 1 MHz.
