Kerr nonlinear oscillators driven by a two-photon process are promising systems to encode
quantum information and to ensure a hardware-efficient scaling towards fault-tolerant …

We consider the possibility of generation steerable states in Bose–Hubbard system
composed of three interacting wells in the form of a triangle. We show that although our …

Relying on weak cross-Kerr nonlinearities, we propose a nearly deterministic generation
scheme of the three-photon polarization-entangled perfect W state which can be applied to …

We develop two efficient measurement-based schemes for remotely preparing arbitrary
three-and four-particle W-class entangled states by utilizing genuine tripartite Greenberg …

We study the squeezing dynamics in a Kerr-nonlinear oscillator, and quantify the
metrological usefulness of the resulting states. Even if the nonlinearity limits the attainable …

This work discusses quantum states defined in a finite-dimensional Hilbert space. In
particular, after the presentation of some of them and their basic properties, the work …

We discuss a model comprised of a chain of three Kerr-like nonlinear oscillators pumped by
two modes of external coherent field. We show that the system can be treated as nonlinear …

The engineering of Kerr and time-dependent coupling interactions is of great attention for
treating quantum information in quantum systems and for investigating the collective …

We show, in the context of single-photon detection, that an atomic three-level model for a
transmon in a transmission line does not support the predictions of the nonlinear …

W-type entangled states can be used as quantum channels for, eg, quantum teleportation,
quantum dense coding and quantum key distribution. In this work, we propose a way to …
