We present a general method to detect nonclassical radiation fields with systems of on-off detectors. We especially study higher order correlations for the identification of nonclassical radiation. This allows us to directly characterize quantum correlations by the statistics measured with systems of on-off detectors. Additionally, we generalize our method to multiple detector systems for measurements of correlations between light fields. We also consider multi-mode radiation fields and isolate nonclassicality in terms of the space time correlations. Finally, we present results for the quantum statistics using on-off detectors operating in nonlinear detection modes.

“…The quantum statistic characteristics of the photon blockade have two important characteristics: sub-Poissonian photon statistics and photon antibunching. Sub-Poissonian statistics can be experimentally demonstrated when ihe second-order correlation function fulfills the inequality g(2)(r) < 1 for all times z, and photon antibunching is demonstrated by the rising of g <2,(r), with r increasing from 0 to larger values, while g <2)(0) < g{2)(z) [2,62], Similarly, the standard second-order correlation function in the weak-coupling scenario is not correct to describe the statistic characteristics of photons in the regime of the strong interaction between the qubit and the cavity mode. Following the modified input-output relations in Refs.…”

The output incoherent spectrum and the photon blockade for the two-photon near-resonant excitation are numerically investigated by using the modified theories which are valid for an arbitrary degree of the qubit-cavity interaction. Owing to the effects of strong coupling of the system, the relaxation coefficients of the system are very sensitive to the coupling strength between the qubit and the cavity mode, which results in the redistribution of the populations and the appearance of the population inversion between the ground state and the first excited state, and it is demonstrated by the intensity of the output incoherent spectrum. The redistribution of the populations leads to one cascaded decay channel being weakened and the other possibly being enhanced significantly. Moreover, by adjusting the detuning between the qubit and the cavity mode, the phenomenon of the intercrossing in the energy levels appears. Through choosing the proper two-photon near-resonant excitation of the externa) classical driving field, the strong-coupling qubit-cavity system effectively causes one cascaded decay channel to realize the two-photon blockade. It is shown that the two-photon blockade can be further enhanced by one cascaded decay channel.

“…On the basis of the inequality (12.16) Mandel [29] (see also [30]) defined sub-Poissonian and super-Poissonian statistics in quantum optics in dependence on the sign of this quantity, "sub"-Poissonian if With effort to the difficult task to implement the measurement theory to photon statistics [7] [8] [11] [31] Paul calculated and discussed anti-bunching of states as a typical non-classical property with no correspondence in classical optics in [32] and in [33] (anti-bunching occasionally renamed there in anti-correlations). In a short paper of Zou and Mandel [34] these authors reclaimed that Paul [32] does not consider anti-bunching and bunching but instead of this sub-and super-Poissonian statistics and that anti-bunching is not a property of a state but a property of the time evolution of a state when the time derivative of the quantity …”
