Local Observables Characterize Maximally Entangled States
2010/11/8
Maximally entangled states (MES) represent a valuable resource in quantum information processing. In $N$-qubit systems the MES are $N$-GHZ states, i.e. the collection of $\ket{GHZ_N}=\frac{1}{\sqrt{2}...

2010/10/21
We propose a practical physical system for creation of a stationary entanglement by dissipation without employing the environment engineering techniques. The system proposed is composed of two perfect...
Entangled states considered as physical representations of classical algorithms
Entangled states physical representations classical algorithms
2010/10/21
There are good reasons to believe that we are classical algorithms run on (effectively) classical machines. However, the fact that a physical state of a system in a universe described by a classical d...

2010/10/20
In this work we generate two-photon hybrid entangled states (HES), where the polarization of one photon is entangled with the transverse spatial degree of freedom of the second photon. The photon pair...

Future quantum technologies rely heavily on the possibility of high-efficiency protection of quan-tum entanglement against environment-induced decoherence. A recent study showed that an exten-sion of ...
Efficient creation of maximally entangled states by modulation of tunneling rates
entangled states modulation of tunneling rates
2010/4/16
For systems described by the two-site Bose-Hubbard Hamiltonian, we show that a sinusoidal modulation of the tunneling matrix element assists higher-order co-tunneling processes. Using this mechanism, ...

We extend the matrix decomposition method(MDM) in classifying the $2\times N\times N$ truly entangled states to $2\times M\times N$ system under the condition of stochastic local operations and classi...

2009/8/14
We investigate quantum teleportation as a tool to study the thermally entangled state of a two-qubit Heisenberg XXZ chain. Our work is mainly to investigate the characteristics of a Heisenberg XXZ cha...

2010/4/8
We prove that every entangled state is useful as a resource for the problem of minimum-error channel discrimination. More specifically, given a single copy of an arbitrary bipartite entangled state, i...

2010/4/8
We establish a technique to find the states with most robust entanglement in dissipative quantum systems and explicitly construct those state for various environments.
