Abstract

We observe entanglement of two remote atomic qubits, by generating entangled state of an atomic qubit and a single photon, transmitting the photon to an adjacent laboratory, and converting the photon into an atomic qubit.

Entanglement of Remote Atomic Qubits

Dzmitry Matsukevich, T. Chanelière, S. D. Jenkins +3 more

We report observations of entanglement of two remote atomic qubits, achieved by generating an entangled state of an atomic qubit and a single photon at site , transmitting the photon to site in an adjacent laboratory through an optical fiber, and converting the photon into an atomic qubit. Entanglement of the two remote atomic qubits is inferred by performing, locally, quantum state transfer of each of the atomic qubits onto a photonic qubit and subsequent measurement of polarization correlations in violation of the Bell inequality [EQUATION: SEE TEXT]. We experimentally determine [EQUATION: SEE TEXT]. Entanglement of two remote atomic qubits, each qubit consisting of two independent spin wave excitations, and reversible, coherent transfer of entanglement between matter and light represent important advances in quantum information science.

Remote entanglement between a single atom and a Bose-Einstein condensate

Carolin Hahn, Matthias Lettner, Martin Mücke +7 more

Entanglement has been recognised as a puzzling yet central element of quantum physics. While photons serve as flying qubits to distribute entanglement, the entanglement of stationary qubits at remote sites is a key resource for envisioned applications like distributed quantum computing. In our experiment we create remote entanglement between a single atom located inside a high-finesse optical cavity and a Bose-Einstein condensate (BEC). To this end we generate a single photon in the atom-cavity system, entangling the photon polarisation with the atomic Zeeman state. The photon is transported to a different laboratory in an optical fiber, where it is stored in a BEC employing electromagnetically induced transparency (EIT). This converts the atom-photon entanglement into remote matter-matter entanglement. Subsequently we map the matter-matter entanglement onto photon-photon entanglement. The experimental setup is sketched in Fig. 1.

Remote Entanglement of Two Single Atoms

Carolin Hahn

This thesis reports on the generation of entanglement between two single atoms, located in different laboratories at a distance of 21 m. The entanglement is established in the conceptually most fundamental way - by exchange of a single photon. To this end, we efficiently create high-fidelity entanglement between one of the atoms and a photon, and then faithfully map the entanglement onto the other atom. Both the photon emission and absorption process are facilitated by employing high-finesse optical resonators that strongly enhance the coupling between light and matter.

Measurement induced entanglement for excitation stored in remote atomic ensembles

We report the observation of heralded entanglement between remote atomic ensembles. The detection of an emitted photon projects the ensembles into an entangled state with one joint excitation stored in the whole system.

Remote Preparation of Single-Photon “Hybrid” Entangled and Vector-Polarization States

Julio T. Barreiro, Tzu-Chieh Wei, Paul G. Kwiat

Quantum teleportation faces increasingly demanding requirements for transmitting large or even entangled systems. However, knowledge of the state to be transmitted eases its reconstruction, resulting in a protocol known as remote state preparation. A number of experimental demonstrations to date have been restricted to single-qubit systems. We report the remote preparation of two-qubit "hybrid" entangled states, including a family of vector-polarization beams. Our single-photon states are encoded in the photon spin and orbital angular momentum. We reconstruct the states by spin-orbit state tomography and transverse polarization tomography. The high fidelities achieved for the vector-polarization states opens the door to optimal coupling of down-converted photons to other physical systems, such as an atom, as required for scalable quantum networks, or plasmons in photonic nanostructures.

Dynamics of Entanglement Transfer from Squeezed Field to Remote Atomic Qubits

Paulo José dos Reis, S. Shelly Sharma, Naresh Kumar Sharma

Dynamics of entanglement transfer from two-mode squeezed field and initially entangled atomic qubit pair to atomic qubits located in remote cavities is examined. Remote qubits become entangled through interaction with two mode squeezed light.
