Exploring Multipartite Steering Effect Using Bell Operators
While Bell operators are exploited in detecting Bell nonlocality and entanglement classification, we demonstrate their usefulness in exploring Einstein−Podolsky−Rosen (EPR) steering, which represents the quantum correlation intermediate ...

Graph Entropy Associated with Multilevel Atomic Excitation
A graph-model is presented to describe multilevel atomic structure. As an example, we take the double Λ configuration in alkali-metal atoms with hyperfine structure and nuclear spin I = 3 / 2 , as a graph with four vertices.

Quantum chaos in small quantum networks [PDF]
We study a 2-spin quantum Turing architecture, in which discrete local rotations _m of the Turing head spin alternate with quantum controlled NOT-operations. We show that a single chaotic parameter input _m leads to a chaotic dynamics in the entire Hilbert space.

Building quantum neural networks based on swap test [PDF]
Artificial neural network, consisting of many neurons in different layers, is an important method to simulate humain brain. Usually, one neuron has two operations: one is linear, the other is nonlinear.

Semidefinite Tests for Quantum Network Topologies. [PDF]
Quantum networks play a major role in long-distance communication, quantum cryptography, clock synchronization, and distributed quantum computing. Generally, these protocols involve many independent sources sharing entanglement among distant parties that,

Epsilon-Near-Zero Grids for On-chip Quantum Networks [PDF]
Realization of an on-chip quantum network is a major goal in the field of integrated quantum photonics. A typical network scalable on-chip demands optical integration of single photon sources, optical circuitry and detectors for routing and processing of

Quantum Switchboard with Coupled-Cavity Array
The ability to control the flow of quantum information is deterministically useful for scaling up quantum computation. In this paper, we demonstrate a controllable quantum switchboard which directs the teleportation protocol to one of two targets, fully ...

Generation of Schrödinger Cat States in a Hybrid Cavity Optomechanical System
We present an alternative scheme to achieve Schrödinger cat states in a strong coupling hybrid cavity optomechanical system. Under the single-photon strong-coupling regime, the interaction between the atom–cavity–oscillator system can induce the ...
