Light-to-matter entanglement transfer in optomechanics

EA Sete, H Eleuch, CH Raymond Ooi - Journal of the Optical Society …, 2014 - opg.optica.org
We analyze a scheme to entangle the movable mirrors of two spatially separated
nanoresonators via a broadband squeezed light. We show that it is possible to transfer the …

Entanglement between charge qubits induced by a common dissipative environment

LD Contreras-Pulido, R Aguado - Physical Review B—Condensed Matter and …, 2008 - APS
We study entanglement generation between two charge qubits due to the strong coupling
with a common bosonic environment (Ohmic bath). The coupling to the boson bath is a …

Dynamical entanglement transfer for quantum-information networks

M Paternostro, W Son, MS Kim, G Falci… - Physical Review A—Atomic …, 2004 - APS
A key element in the architecture of a quantum-information processing network is a reliable
physical interface between fields and qubits. We study a process of entanglement transfer …

Entanglement reciprocation between qubits and continuous variables

J Lee, M Paternostro, MS Kim, S Bose - Physical review letters, 2006 - APS
We investigate how entanglement can be transferred between qubits and continuous-
variable (CV) systems. We find that one ebit borne in maximally entangled qubits can be …

Quantum-state transfer in imperfect artificial spin networks

M Paternostro, GM Palma, MS Kim, G Falci - Physical Review A—Atomic …, 2005 - APS
High-fidelity quantum computation and quantum state transfer are possible in short spin
chains. We exploit a system based on a dispersive qubit-boson interaction to mimic XY …

Entanglement transfer, accumulation and retrieval via quantum-walk-based qubit–qudit dynamics

The generation and control of quantum correlations in high-dimensional systems is a major
challenge in the present landscape of quantum technologies. Achieving such non-classical …

Collapse-revival and stability of magnon-superconducting qubit entanglement in a tripartite hybrid cavity system

MS Kheirabady, MK Tavassoly, S Salimian - Optik, 2023 - Elsevier
In this paper we pay our attention to the generation and manipulation of bipartite
entanglement in a hybrid cavity system which is comprised of cavity microwave photons, a …

Entanglement, purity, and energy: Two qubits versus two modes

D McHugh, M Ziman, V Bužek - Physical Review A—Atomic, Molecular, and …, 2006 - APS
We study the relationship between the entanglement, mixedness, and energy of two-qubit
and two-mode Gaussian quantum states. We parametrize the set of allowed states of these …

Optomechanical to mechanical entanglement transformation

G Vacanti, M Paternostro, GM Palma… - new journal of …, 2008 - iopscience.iop.org
We present a scheme for generating entanglement between two mechanical oscillators that
have never interacted with each other by using an entanglement-swap** protocol. The …

Improving the entanglement transfer from continuous-variable systems to localized qubits using non-Gaussian states

F Casagrande, A Lulli, MGA Paris - … Review A—Atomic, Molecular, and Optical …, 2007 - APS
We investigate the entanglement transfer from a bipartite continuous-variable (CV) system to
a pair of localized qubits assuming that each CV mode couples to one qubit via the off …
