Measurement-assisted non-Gaussian gate for Schrödinger cat states preparation: Fock resource state versus cubic phase state

European Physical Journal D : Atomic, Molecular and Optical Physics, 2023
In this paper, we consider the preparation of Schrödinger cat states using a measurement-assisted gate based on the Fock resource state, the quantum non-demolition entangling operation, and the homodyne measurement.

Nonclassicality of entangled Schrödinger cat states associated to generalized displaced Fock states

Physica Scripta, 2023
In this paper, we introduce some distinct classes of entangled cat states associated to generalized displaced Fock states. For this purpose, we use the formalism of nonlinear coherent states corresponding to nonlinear oscillator algebra which yields ...

Multi-qubit gates and Schrödinger cat states in an optical clock

Nature
Many-particle entanglement is a key resource for achieving the fundamental precision limits of a quantum sensor1. Optical atomic clocks2, the current state of the art in frequency precision, are a rapidly emerging area of focus for entanglement-enhanced ...

High-Coherence Kerr-Cat Qubit in 2D Architecture

Physical Review X
The Kerr-cat qubit is a bosonic qubit in which multiphoton Schrödinger cat states are stabilized by applying a two-photon drive to an oscillator with a Kerr nonlinearity.

Schrödinger cat states of a nuclear spin qudit in silicon

Nature Physics
High-dimensional quantum systems are a valuable resource for quantum information processing. They can be used to encode error-correctable logical qubits, which has been demonstrated using continuous-variable states in microwave cavities or the motional ...

Effective and Robust Generation of Deterministic Magnon Schrödinger Cat States in the Hybrid System

Advanced Quantum Technologies
A scheme is proposed for effective and robust generation of magnon Schrödinger cat states in the hybrid optomagnonical system. The Schrödinger cat states can be generated from the vacuum states and the physical model is easy to be implemented.

Entangling Schrödinger’s cat states by bridging discrete- and continuous-variable encoding

Nature Communications
In quantum information processing, two primary research directions have emerged: one based on discrete variables (DV) and the other on the structure of quantum states in a continuous-variable (CV) space.
