In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

We propose that photon blockade can be enabled by a two-photon absorption environment.
The validity of this conclusion is confirmed by studying the blockade in a driven single-mode …

A scheme of nonreciprocal conventional phonon blockade (PB) is proposed in a spinning
optomechanical resonator coupled with a two-level atom. The coherent coupling between …

Quantum systems are affected by interactions with their environments, causing decoherence
through two processes: pure dephasing and energy relaxation. For quantum information …

We describe a novel type of blockade in a hybrid mode generated by linear coupling of
photonic and phononic modes. We refer to this effect as hybrid photon–phonon blockade …

Based on the scattering matrix method, we theoretically demonstrate that the chiral
interaction can induce the almost perfect photon blockade (PB) in the waveguide-cavity …

The Dicke model is a paradigmatic quantum-optical model describing the interaction of a
collection of two-level systems with a single bosonic mode. Effective implementations of this …

We study the photon antibunching effect in a bimode nano-optical cavity filled with the
second-order nonlinear material and embedded with a quantum dot. Analytical results show …

The coherent process that a single photon simultaneously excites two qubits has recently
been theoretically predicted by Garziano et al.[L. Garziano, V. Macrì, R. Stassi, O. Di Stefano …

Unconventional photon blockade refers to the suppression of multiphoton states in weakly
nonlinear optical resonators via the destructive interference of different excitation pathways …
