Influence of the vibrational modes in the transmission of electronic states of trapped ions in different coupled cavities

Abstract

In this paper, we present a system formed by two electromagnetic cavities coupled by an optical fibre, each one interacting with a trapped ion. In the carrier band, we observe the one-qubit state transfer between the internal state of the ions and how the transmission time can be influenced by the vibration motion of the ions.

Two-qubit state transfer between trapped ions using electromagnetic cavities coupled by an optical fibre

Fabiano Kenji Nohama, José Antonio Roversi

In this paper, we study a system formed by two electromagnetic cavities coupled by an optical fibre, where each cavity interacts with a trapped ion. In this model we observe that it is possible to transmit two-qubit states from the ion in cavity 1 to the ion in cavity 2, both connected by an optical fibre. The mentioned states consist of vibration and internal degrees of freedom of the ions. The presence of a reservoir with temperature T = 0 is included in the model. Taking into account the presence of the reservoir, we conclude that the transmission is reliable even for dissipation rates observed in experiments.

Scheme for Implementing Quantum State Transfer in Cavity QED with Trapped Ion

Shao-Hua Xiang, Zheng Qing-yun

We propose a physical scheme for implementing quantum state transfer utilizing the interaction of a two-level trapped ion with a quantum monomode electromagnetic field within an optical cavity.The results show that by controlling the frequency of cavity field to be resonant with the carrier,quantum information can be transferred between cavity field and the internal state of the ion without the need for the selected measurement of the qubits.Quantum information may also be transmitted from the vibrational state of the ion into cavity mode,from the internal state of the ion into its vibration state, and from a single-qubit state into an entangled bipartite state by means of the measurement on the qubits when we tune the light field to the first blue sideband.A practical model of a quantum network is proposed.Finally,we analyze the experimental feasibility of the present scheme.

Transfer of Two Qubits States Using Coupled Cavities in Off-Resonance Systems

Julio Cesar González Henao

In this work we studied a system consisting of a pair of two-level trapped ions in coupled optics cavities, where we analyze the transfer of states of two qubits from the degrees of freedom (of movement and of internal states) of one ion to another. This system was studied near the blue side band frequency with a small gap. With analytical results obtained was possible to calculate the fidelity of transfer of entangled qubits.

Coherent coupling between the motional fluctuation of a mirror and a trapped ion inside an optical cavity: Memory, state transfer, and entanglement

Devender Garg, Asoka Biswas

We show how the motional fluctuations of two systems of very different sizes---a trapped ion and a mirror---can be coupled coherently, via their common interaction with an optical cavity. Specifically, we show that the fluctuations can be transferred from one system to the other by using pulsed excitation of the cavity mode, and vibrational fluctuations can exhibit entanglement in steady state. We numerically display a sudden death of this entanglement at certain pulse parameters and ambient equilibrium temperature. More interestingly, the state of the driving pulse can also be coherently mapped, in a selective way, into the vibrational mode of the trapped ion or the mirror, which acts as a quantum memory for the optical pulse. We further present a detailed analysis to show that it is also possible to map the state of the pulse into a binomial entangled state of its vibrational fluctuations. We finally investigate how to sympathetically cool the mirror by cooling the ionic vibration, thanks to an effective coupling between the two modes.

Motional entanglement for two trapped ions in cascaded optical cavities

Gao‐xiang Li, Huatang Tan, Shaoping Wu

The time-dependent characteristic function for the vibrational quanta of two ions separately trapped in two cascaded optical cavities is obtained analytically beyond the bad cavity limit, in which the motional mode of the ion in the first cavity is coupled to the cavity field via an effective parametric interaction and that of the ion in the second cavity via a linear-mixing interaction as proposed by Peng and Parkins [Phys. Rev. A 65, 062323 (2002)]. It is found that the two ions develop in a two-mode mixed Gaussian entangled state if there exists a unidirectional coupling from the first cavity to the second one.

Entanglement between motional states of a single trapped ion and light

F. L. Semião, A. Vidiella-Barranco, José Antonio Roversi

We propose a generation method of Bell-type states involving light and the vibrational motion of a single trapped ion. The trap itself is supposed to be placed inside a high-$Q$ cavity sustaining a single mode, quantized electromagnetic field. Entangled light-motional states may be readily generated if a conditional measurement of the ion's internal electronic state is made after an appropriate interaction time and a suitable preparation of the initial state. We show that all four Bell states may be generated using different motional sidebands (either blue or red), as well as adequate ionic relative phases.
