- Abstract: We propose a mechanism to engineer an $n$-photon blockade in a nonlinear
cavity with an $n$-photon parametric drive $\lambda(\hat{a}^{\dag
n}+\hat{a}^n)$. When an $n$-photon-excitation resonance condition is satisfied,
the presence of n photons in the cavity suppresses the absorption of the
subsequent photons. To confirm the validity of this proposal, we study the
n-photon blockade in an atom-cavity system, a Kerr-nonlinear resonator, and
two-coupled Kerr nonlinear resonators. Our results demonstrate that $n$-photon
bunching and $(n+1)$-photon antibunching can be simultaneously obtained in
these systems. This effect is due both to the anharmonic energy ladder and to
the nature of the $n$-photon drive. To show the importance of the drive, we
compare the results of the $n$-photon drive with a coherent (one-photon) drive,
proving the enhancement of antibunching in the parametric-drive case. This
proposal is general and can be applied to realize the $n$-photon blockade in
other nonlinear systems.

A generalization of the quantum Rabi model is obtained by replacing the linear (dipole) coupling between the two-level system and the radiation mode.
If each spin flip involves $k$ photons, it is called the "$k$-photon" quantum Rabi model.

multiphotonic interference and asymptotic classical correspondence [44.99833362998488]
We present the analysis of the quantum two-port interferometer in the $n rightarrow infty$ limit of $n$ partially indistinguishable photons.
Our main result is that the output distribution is dominated by the $O(sqrtn)$ channels around a certain $j*$ that depends on the degree of indistinguishability.
The form is essentially the doubly-humped semi-classical envelope of the distribution that would arise from $2 j*$ indistinguishable photons, and which reproduces the corresponding classical intensity distribution.

We show the generation of unbalanced two-photon entanglement in the Laguerre-Gaussian (LG) transverse-spatial degree-of-freedom.
Taking a cue from the $N00N$ state nomenclature, we call these types of states $ell 00 ell$-entangled.
We find that our generated states have fidelities of 95.31% and 89.80% to their respective ideal maximally entangled states.

No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory.
Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons.
This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.
