Hybrid quantum information processing [PDF]

, 2014
The development of quantum information processing has traditionally followed two separate and not immediately connected lines of study. The main line has focused on the implementation of quantum bit (qubit) based protocols whereas the other line has been

Quantum detector tomography of MgB2nanowire

Quantum 2.0 Conference and Exhibition
We perform quantum detector tomography of a novel, unknown detector – superconducting magnesium diboride nanowire, and show that reconstructed POVM elements provide insights into underlying detection mechanism and multiphoton detection efficiencies.

Intra-individual comparison of coronary calcium scoring between photon counting detector- and energy integrating detector-CT: Effects on risk reclassification

Frontiers in Cardiovascular Medicine, 2023
PurposeTo compare coronary artery calcium volume and score (CACS) between photon-counting detector (PCD) and conventional energy integrating detector (EID) computed tomography (CT) in a phantom and prospective patient study.MethodsA commercially ...

Metrology with Unknown Detectors [PDF]

, 2015
The best possible precision is one of the key figures in metrology, but this is established by the exact response of the detection apparatus, which is often unknown.

Estimating the Product of the X-ray Spectrum and Quantum Detection Efficiency of a CT System and Its Application to Beam Hardening Correction

Sensors, 2021
Lab-based X-ray computed tomography (XCT) systems use X-ray sources that emit a polychromatic X-ray spectrum and detectors that do not detect all X-ray photons with the same efficiency.

Fourier domain optical coherence tomography system with balance detection [PDF]

, 2012
A Fourier domain optical coherence tomography system with two spectrometers in balance detection is assembled using each an InGaAs linear camera. Conditions and adjustments of spectrometer parameters are presented to ensure anti-phase channeled spectrum ...

Choice of Measurement Sets in Qubit Tomography

, 2007
Optimal generalized measurements for state estimation are well understood. However, practical quantum state tomography is typically performed using a fixed set of projective measurements and the question of how to choose these measurements has been ...

Mapping the optimal route between two quantum states [PDF]

, 2014
A central feature of quantum mechanics is that a measurement is intrinsically probabilistic. As a result, continuously monitoring a quantum system will randomly perturb its natural unitary evolution.

Curved digital X-ray detectors

npj Flexible Electronics, 2020
A curved image sensor on plastic foil has been developed for cone beam computed tomography (CBCT) X-ray imaging. The image sensor of about 6 × 8 cm2 size has been built on a thin polyimide foil with an indium gallium zinc oxide (IGZO) backplane and an ...

Robust concurrent remote entanglement between two superconducting qubits

, 2016
Entangling two remote quantum systems which never interact directly is an essential primitive in quantum information science and forms the basis for the modular architecture of quantum computing.
