Abstract

We have experimentally realizerd a technique to generate, control and measure entan-gled qutrits, 3-dimensional quantum systems. This scheme uses spontaneous parametricdown converted photons and unbalanced 3-arm fiber optic interferometers in a schemeanalogous to the Franson interferometric arrangement for qubits. The results reveal asource capable of generating maximally entangled states with a net state fidelity F =0.985 ± 0.018, Further the control over the system reveals a high, net, 2-photon interfer-ence fringe visibility, V = 0.919 ± 0.026. This has all been done at telecom wavelengthsthus facilitating the advancement towards long distance higher dimensional quantumcommunication.

Schemes generating entangled states and entanglement swapping between photons and three-level atoms inside optical cavities for quantum communication

We propose quantum information processing schemes based on cavity quantum electrodynamics (QED) for quantum communication. First, to generate entangled states (Bell and Greenberger---Horne---Zeilinger [GHZ] states) between flying photons and three-level ...
Can quantum discord increase in a quantum communication task?

Quantum teleportation of an unknown quantum state is one of the few communication tasks which has no classical counterpart. Usually the aim of teleportation is to send an unknown quantum state to a receiver. But is it possible in some way that the ...
Disentanglement and quantum states transitions dynamics in spin-qutrit systems: dephasing random telegraph noise and the relevance of the initial state

Using negativity and realignment criterion as quantifiers of free and bound entanglements respectively, we present in details the analytical study of the entanglements and quantum states transitions dynamics in a two-qutrit system driven by dephasing ...
