PY 2019 BP 012166 (1 to 4) VL 1410 DI 10.1088/1742-6596/1410/1/012166 DE SSPD; SNSPD; quantum detector tomography; QDT AB We present data of quantum detector tomography for the samples specifically optimized for this problem. Using this method, we take results of hot-spot correlation length of 17 ± 2 nm. ER
