Abstract

We consider the entanglement transformations of the protocols that convert quantum qubit system to continuous variable system and convert it back. Here the quantum D/A conversion protocol maps finite-dimensional input states onto continuous variable states while the quantum A/D conversion protocol maps two mode squeezed state onto entangled state in 2x2 dimensions. Quantum carrier is investigated when pure qubit state interacts with coherent state.

Conversion of entanglement between continuous variable and qubit systems

We investigate how entanglement can be transferred between continuous variable and qubit systems. We find that a two-mode squeezed vacuum state and a continuous variable Werner state can be converted to the product states of infinitive number of two-qubit states while keeping the entanglement. The reverse process is also possible.

Perfect A/D conversion of entanglement

Xiaoyu Chen

We investigate how entanglement can be perfectly transfered between continuous variable and qubits system. We find that a two-mode squeezed vacuum state can be converted to the product state of an infinitive number of two-qubit states while keeping the entanglement. The reverse process is also possible. The interaction Hamitonian is a kind of non-linear Jaynes-Cumings Hamiltonian.

CONVERSION OF ENTANGLEMENT BETWEEN CONTINUOUS VARIABLE AND QUBIT SYSTEMS VIA INTERACTION

Xiaoyu Chen, Li-zhen Jiang

We investigate how entanglement can be transferred between continuous variable and qubit systems. We find that a two-mode squeezed vacuum state and a continuous variable Werner state can be converted to the product states of an infinitive number of two-qubit states while keeping the entanglement. The reverse process is also possible. The proposed conversion model is theoretically viable but difficult to realize in the laboratory.

Enhanced dynamical entanglement transfer with multiple qubits

We present two strategies to enhance the dynamical entanglement transfer from continuous-variable (CV) to finite-dimensional systems by employing multiple qubits. First, we consider the entanglement transfer to a composite finite-dimensional system of many qubits simultaneously interacting with a bipartite CV field. We show that, considering realistic conditions in the generation of CV entanglement, a small number of qubits resonantly coupled to the CV system are sufficient for an almost complete dynamical transfer of the entanglement. Our analysis also sheds further light on the transition between the microscopic and macroscopic behaviors of composite finite-dimensional systems coupled to bosonic fields (like atomic clouds interacting with light). Furthermore, we present a protocol based on sequential interactions of the CV system with some ancillary qubit systems and on subsequent measurements, allowing us to probabilistically convert CV entanglement into ``almost-perfect'' Bell pairs of two qubits. Our proposals are suited for realizations in various experimental settings, ranging from cavity-QED to cavity-integrated superconducting devices.

Correspondence between continuous-variable and discrete quantum systems of arbitrary dimensions

Časlav Brukner, Myungshik S. Kim, Jian-Wei Pan +1 more

We establish a mapping between a continuous-variable (CV) quantum system and a discrete quantum system of arbitrary dimension. This opens up the general possibility to perform any quantum information task with a CV system as if it were a discrete system. The Einstein-Podolsky-Rosen state is mapped onto the maximally entangled state in any finite-dimensional Hilbert space and thus can be considered as a universal resource of entanglement. An explicit example of the map and a proposal for its experimental realization are discussed.

Entanglement transfer from continuous variables to qubits

Son, W, Kim, M S, Lee, J +1 more

We show that two qubits can be entangled by local interactions with an entangled two-mode continuous variable state. This is illustrated by the evolution of two two-level atoms interacting with a two-mode squeezed state. Two modes of the squeezed field are injected respectively into two spatially separate cavities and the atoms are then sent into the cavities to resonantly interact with the cavity field. We find that the atoms may be entangled even by a two-mode squeezed state which has been decohered while penetrating into the cavity.
