Quantum detector tomography of high-dimensional multiplexed superconducting detectors

Conference on Lasers and Electro-Optics, 2021
We demonstrate quantum detector tomography of three different multiplexed SNSPDs, including a nonlinear detector of dimension > 103. We use this to extract efficiency, dark-count and cross-talk probability from just four elements of the reconstructed POVMs.

Quantum Detector Tomography on Superconducting Single Photon Detectors

Research in Optical Sciences, 2014
We use quantum detector tomography (QDT) to investigate the physics of photodetection in superconducting single photon detectors. With this, we achieve the key promise of QDT: agnostic, model-free investigation of an unknown detector.

How noise affects quantum detector tomography

Journal of Applied Physics, 2015
We determine the full photon number response of a NbN superconducting nanowire single photon detector via quantum detector tomography, and the results show the separation of linear, effective absorption efficiency from the internal detection efficiencies.

Photon-counting detectors in computed tomography: from quantum physics to clinical practice

Der Radiologe, 2021
Over the last decade, a fundamentally new type of computed tomography (CT) detectors has proved its superior capabilities in both physical and preclinical evaluations and is now approaching the stage of clinical practice. These detectors are able to discriminate single photons and quantify their energy and are hence called photon-counting detectors ...

Quantum State Tomography with Array Detectors

Physical Review Letters, 2000
I propose a method for measuring the quantum state of an optical field that occupies a mode having a complicated spatial structure. The technique uses array detectors and a single, plane-wave local oscillator beam. The advantage of using array detectors is that the local oscillator is not mode matched to the field being measured, yet the deleterious ...

Approaching Mega-Scale Quantum Detector Tomography using High-Performance Computing

Optica Quantum 2.0 Conference and Exhibition, 2023
Quantum characterization tools must keep up with the ever-increasing size of detector arrays for quantum applications. We show quantum detector tomography per-formed on a supercomputer which reconstructs the POVMs up to 2.5 · 105 photons.
