Cavity-Enhanced Atom-Photon Entanglement with Subsecond Lifetime
نویسندگان
چکیده
A cold atomic ensemble suits well for optical quantum memories, and its entanglement with a single photon forms the building block networks that give promise many revolutionary applications. Efficiency lifetime are among most important figures of merit memory. In this paper, we report realization between an single-photon subsecond high efficiency. We engineer dual control modes in ring cavity to create make use 3-dimensional lattice prolong memory lifetime. The efficiency is 38% 0.1 second storage. verify atom-photon after 1 storage by testing Bell inequality result $S=2.36\pm0.14$.

Atom-Photon Entanglement
Entanglement is the key element for many experiments in quantum communication and information. Especially for future applications like quantum networks or the quantum repeater it is mandatory to achieve entanglement also between separated quantum processors. For this purpose, entanglement between different quantum objects like atoms and photons forms the interface between atomic quantum memorie...
متن کاملAtom-atom entanglement by single-photon detection.
A scheme for entangling distant atoms is realized, as proposed in the seminal paper by [C. Cabrillo et al., Phys. Rev. A 59, 1025 (1999)]. The protocol is based on quantum interference and detection of a single photon scattered from two effectively one meter distant laser cooled and trapped atomic ions. The detection of a single photon heralds entanglement of two internal states of the trapped ...
متن کاملPhoton-photon entanglement with a single trapped atom.
An experiment is performed where a single rubidium atom trapped within a high-finesse optical cavity emits two independently triggered entangled photons. The entanglement is mediated by the atom and is characterized both by a Bell inequality violation of S=2.5, as well as full quantum-state tomography, resulting in a fidelity exceeding F=90%. The combination of cavity-QED and trapped atom techn...
متن کاملEntanglement of a mesoscopic field with an atom induced by photon graininess in a cavity.
We observe that a mesoscopic field made of several tens of microwave photons exhibits quantum features when interacting with a single Rydberg atom in a high-Q cavity. The field is split into two components whose phases differ by an angle inversely proportional to the square root of the average photon number. The field and the atomic dipole are phase entangled. These manifestations of photon gra...
