Finally, we discuss the implications of our results for practical detector design.doi:10.1016/0304-3991(82)90172-3M.T. BrowneJ.F.L. WardElsevier B.V.UltramicroscopyBrowne MT, Ward JFL. 1982. Detectors for STEM, and the measurement of their detective quantum efficiency. Ultra- microscopy 7:...
The FDP approach is easily adapted to a variety of measurement devices and the experimental implementation presented shows its viability for detectors with complex response. We anticipate that this approach to detector calibration and QSE will become a standard method to characterize measurement response ...

Figures3b, c report the measured Mermin parametersμand\(\tilde{\mu }\)for all the (27 + 2) classes of hypergraph (graph) states. When performing measurement for each state, its local projectors {\({a}_{i},{a}_{i}^{{\prime} }\)} for each qubit are optimized by an algorit...
More realistically, we would consider screens or absorbing detectors, in which case the final state of the measured particle cannot be determined. This does not restrict the arguments because we are not interested in the final states of absorbed particles but only in the measurement outcomes and ...
If the measurement is successful (i.e., one of the detectors registers one photon), we will prepare the ensembles L and R into another EME state. The new φ-parameter is given by φ1 + φ2, where φ1 and φ2 denote the old φ-parameters for the two segment EME states. Even in ...
The continuous-variable measurement-device-independent quantum key distribution (CV-MDI-QKD) is a promising candidate for the immunity to side-channel attacks, but unfortunately seems to face the limitation of transmission distance in contrast to discrete-variable (DV) counterpart. In this paper, we...
In addition, high counting rate single-photon detectors are assumed for quantum state measurement29,30. In this case, the photon counting saturation issue is negligible, and there is no constraint on the value of \(\mu _1\). The simulation results are shown as the blue and red curve in ...
Also, from a conceptual standpoint, it is not self-evident that entanglement in the measurement must, in general, be indispensable for correlation advantages. To address both the practical and conceptual question, we investigate the possibility of using even the most elementary class of joint ...
defined as an isolated system that can be completely characterized by a state vector in a Hilbert space, where its time evolution is described by a unitary transformation and only certain sets of measurements can be done at any one time, leading to the collapse of the system upon measurement....
