چکیده
Submitted for the DAMOP14 Meeting of The American Physical Society Towards a cavity electromagnetically induced transparency based quantum gate EDEN FIGUEROA, ZAKARY BURKLEY, BERTUS JORDAAN, CARL CHEUNG, CHRISTIAN NOELLEKE, CONNOR KUPCHAK, Stony Brook University — The processing of quantum information with photons and atoms has been established as one of the strongest candidates for future quantum technologies. Photons (quantum channels) are capable of encoding quantum information and traveling long distances without decohering, whereas atoms (quantum nodes) readily interact with light and therefore provide a natural platform for mediating interactions and storing it. The development of a node in which deterministic twoqubit gates can be realized still remains an elusive goal for the quantum optics community. The success of a photonic, two-qubit gate is contingent on a photonphoton interaction generating a sufficient relative phase between the fields. This can be achieved by utilizing a combination of cavity quantum-electrodynamics and electromagnetically-induced transparency. In our newly implemented experiment based on a magneto-optical trap coupled to two optical cavities, we aim to realize strong interactions between weak quantum optical fields. We report on the current status of the experiment and discuss possible implementations of photonic quantum gates.

Coupled quantum electrodynamics in photonic crystal cavities towards controlled phase gate operations
In this paper, a scalable photonic crystal cavity array, in which single embedded quantum dots (QDs) are coherently interacting, is studied theoretically. Firstly, we examine the spectral character and optical delay brought about by the coupled cavities interacting with single QDs, in an optical analogue to electromagnetically induced transparency. Secondly, we then examine the usability of thi...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...

متن کاملThree-Way Entanglement and Three-Qubit Phase Gate Based on a Coherent Six-Level Atomic System
We analyze the nonlinear optical response of a six-level atomic system under a configuration of electromagnetically induced transparency. The giant fifth-order nonlinearity generated in such a system with a relatively large cross-phase modulation effect can produce efficient three-way entanglement and may be used for realizing a three-qubit quantum phase gate. We demonstrate that such phase gat...

We investigate a hybrid optomechanical system composed of a micromechanical oscillator as a movable membrane and an atomic three-level ensemble within an optical cavity. We show that a suitably tailored cavity field response via electromagnetically induced transparency (EIT) in the atomic medium allows for strong coupling of the membrane’s mechanical oscillations to the collective atomic ground...
