Fig. 3: Histogram of events for θ = π and N = 1, and the corresponding confusion matrix and efficiency.
From: Coherent interaction-free detection of microwave pulses with a superconducting circuit
(left panels) Histogram of events recorded by the detectors D0, D1, and D2, which are modeled as projectors. Histograms resulting from the experiments, simulations and ideally expected values are shown in blue, red and yellow colors respectively. The results are obtained from 106 realizations of the experiment, and for B-pulse strengths θ = 0, π. The percentage outcome at D0 corresponds to successful interaction-free detection, D2 represents the number of times the pulse is absorbed, and D1 are the inconclusive instances. (right panel) Confusion matrix and efficiency ηc for the detection of π pulses showing the experimental (blue), simulated (red) and ideally expected (yellow) values.
