Entanglement control in hybrid optomechanical systems [PDF]

open access: yes, 2012
We demonstrate the control of entanglement in a hybrid optomechanical system comprising an optical cavity with a mechanical end-mirror and an intracavity Bose-Einstein condensate (BEC).

Controlling entanglement generation in external quantum fields [PDF]

open access: yesJournal of Optics B: Quantum and Semiclassical Optics, 2005
Two, non-interacting two-level atoms immersed in a common bath can become mutually entangled when evolving with a Markovian, completely positive dynamics. For an environment made of external quantum fields, this phenomenon can be studied in detail: one finds that entanglement production can be controlled by varying the bath temperature and the distance

Research Paper: Temperature Effect on the Hybrid Electron Spin- oscillation Entanglement in an Anisotropic Two- dimensional Quantum Dot [PDF]

open access: yesفیزیک کاربردی ایران
Entanglement plays a fundamental role in the field of quantum computing and quantum communication. In real conditions, a physical system is never isolated and inevitably interacts with its surroundings.

A Systematic Review of Evidence on the Clinical Effectiveness of Surveillance Imaging in Children With Medulloblastoma and Ependymoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Effect of control procedures on the evolution of entanglement in open quantum systems

open access: yes, 2013
The effect of a number of mechanisms designed to suppress decoherence in open quantum systems are studied with respect to their effectiveness at slowing down the loss of entanglement.

Control of multiatom entanglement in a cavity [PDF]

open access: yes, 2006
We propose a general formalism for analytical description of multiatomic ensembles interacting with a single mode quantized cavity field under the assumption that most atoms remain un-excited on average.

Quantum control of two-qubit entanglement dissipation [PDF]

open access: yesJournal of Russian Laser Research, 2011
We investigate quantum control of the dissipation of entanglement under environmental decoherence. We show by means of a simple two-qubit model that standard control methods - coherent or open-loop control - will not in general prevent entanglement loss.

From entanglement certification with quench dynamics to multipartite entanglement of interacting fermions

open access: yesPhysical Review Research, 2021
Multipartite entanglement, such as witnessed through the quantum Fisher information (QFI), is a crucial resource for quantum technologies, but its experimental certification is highly challenging.

A brand new strategy of quantum relay strategy based on entanglement swapping

open access: yesDianxin kexue, 2016
Quantum protocols based on entanglement are known as information security,reliability,flexibility and a broad prospect in use.Meanwhile,the fidelity of photons is also required.A new quantum relay strategy was proposed.By setting multi-relays between ...

Entanglement generation in persistent current qubits

open access: yes, 2004
In this paper we investigate the generation of entanglement between two persistent current qubits. The qubits are coupled inductively to each other and to a common bias field, which is used to control the qubit behaviour and is represented schematically ...
