Mode optimization for quantum-state tomography with array detectors
Physical Review A, 2003We demonstrate that it is possible to choose an optimal signal mode for state reconstruction when performing quantum-state tomography with array detectors. The mode optimization is done during the data analysis ~i.e., after all the data have been collected. !

Computed tomography using a terahertz quantum cascade laser and quantum well photo-detector
Journal of Optics, 2013Terahertz computed tomographic imaging has been performed based on an imaging system which includes a terahertz quantum cascade laser as the light source and a terahertz quantum well photo-detector. The main reconstruction methods of filtered back projection, iterative analysis and the wavelet reconstruction technique are adopted and compared.

Extending the quantum tomography of a quasi-photon-number-resolving detector
2023The ability to discriminate the number of photons in a radiation field has a critical role in the implementation of quantum optical technologies. True photon-number-resolving detectors are rare and complex devices, while a quasi-photon-number-resolving detector (qPNRD) is a practical alternative for real-world applications.

A Quantum-Limited Highly Linear Monolithic CMOS Detector for Computed Tomography
IEEE Transactions on Circuits and Systems I: Regular Papers, 2012Computed tomography (CT) detector requires quantizing the wide dynamic range (WDR) photocurrent with high speed. Existing CMOS CT detectors are limited by their low linearity. They also need high-resolution external analog-to-digital converters (ADC) to quantize the WDR.

Quantum Tomography of Superconducting Single Photon Detectors
2014Nanowire superconducting single photon detectors (SSPDs) consist of a thin (~ 4 to 6 nm) and narrow (~ 50 to 200 nm) superconducting wire biased close to the critical current. Operating conditions are such that the absorption of one or more photons locally transfers the detector to its normal state, which then results in a detectable electrical pulse ...

Quantum Detector Tomography of the Infrared Single-Photon Frequency Upconversion Detection System
Quantum Information and Measurement (QIM) 2017, 2017We demonstrated a quantum detector tomography of a synchronously pumped infrared single-photon frequency upconversion detector. A maximum detection efficiency of 37.6% was achieved at 1558 nm with a background noise about 1.0×10−3counts/pulse.
