Abstract

We propose a scheme for high quantum state transfer efficiency between two distant mechanical oscillators. Through coupling separately to two optical cavities connected by an optical fiber, two distant mechanical oscillators achieve a transfer efficiency closing to unity. In the process of analysis, we employed time-varying optomechanical coupling strength as a Gaussian pulse.

Quantum State Transfer between a Mechanical Oscillator and a Distant Moving Atom

Fu Zhang, Yanqing Guo, Guangyao Yang +1 more

We propose a scheme for high fidelity quantum state transfer from a mechanical oscillator to a distant moving atom. In the scheme, two optical cavities connected by an optical fiber are interacted effectively through adiabatically eliminating fiber mode under large detuning limit. The quantum state transfer fidelity can be raised asymptotically to 100% by optimizing the Gaussian pulse G(t), the maximum atom-cavity coupling strength Ωmax, and the atomic velocity v. We also show that the affect of dissipation can be obviously depressed by synchronously increasing Ωmax and v.

High-efficiency quantum state transfer and quantum memory using a mechanical oscillator

Eyob Alebachew Sete, Hichem Eleuch

We analyze an optomechanical system that can be used to efficiently transfer a quantum state between an optical cavity and a distant mechanical oscillator coupled to a second optical cavity. We show that for a moderate mechanical $Q$ factor it is possible to achieve a transfer efficiency of $99.4%$ by using adjustable cavity damping rates and destructive interference. We also show that the quantum mechanical oscillator can be used as a quantum memory device with an efficiency of $96%$ employing a pulsed optomechanical coupling. Although the mechanical dissipation slightly decreases the efficiency, its effect can be significantly reduced by designing a high-$Q$ mechanical oscillator.

A scheme for quantum state transfer between distant atoms

Yong-Cheng Ou, Zhiming Zhang

A scheme is proposed to implement quantum state transfer between two distant atoms through sending the atoms across two distant cavities connected via an optical fiber. The field state, which preserves the information of the first atom, is transmitted from one cavity to the other along the fiber. After the field interacts with the second atom for a defined time, the state transfer can be accomplished with unit efficiency. The realization of this scheme is within current experiment technology.

State Transfer of Two Mechanical Oscillators in Coupled Cavity Optomechanical System

Xiao Rui-ji

This paper investigates a coupled cavity optomechanical system consisting of two Fabry-Perot cavities and the two cavities are coupled via an optical fiber.Every cavity is made of one fixed mirror and a movable mirror,and the movable mirror can be regarded as a mechanical oscillators.Meanwhile,the two cavity modes are driven by classical laser fields.So,the interaction is inevitable between cavities,cavity and moving mirror,cavity and classical field.Firstly,in order to eliminate the two cavity fields,an effective Hamiltonian of the two phonon modes is derived by means of picture transformation,adiabatic eliminating,and rotating wave approximation ignoring the high frequency items,etc.Secondly,if the two mechanical oscillators initially are in coherent states,the coupled mechanical oscillators can be used to transmit state.Finally,in order to verify the analytical result,the fidelity of quantum state is numevically simulated,the result shows that the quantum state can be transferred periodically between the two mechanical oscillators,which is the same as the analytical result.

Transitionless intra-cavity quantum state transfer in optomechanical systems

Hao Zhang, Xue‐Ke Song, Qing Ai +2 more

Quantum state transfer between cavities is crucial for quantum information processing and quantum computation in optomechanical systems. Here, we present the first scheme for the transitionless intra-cavity quantum state transfer based on transitionless quantum driving (TQD) algorithm in optomechanical systems. We also present a physically feasible system for the TQD process based on largely detuned optomechanical cavity. With the Gaussian time-dependence coupling strengths, our scheme can achieve the perfect quantum state transfer with no undesired transition and reduce the dependence of accurately controlling evolution time and interval of coupling strengths. Our computational results show that the TQD process can be accomplished with no need of the mechanical oscillator in its ground state and is also robust to the mechanical dissipation.

Long-distance quantum state transfer through cavity-assisted interaction

Yu-Ning Li, Feng Mei, Ya‐Fei Yu +1 more

We propose a scheme for long-distance quantum state transfer between different atoms based on cavity-assisted interactions. In our scheme, a coherent optical pulse sequentially interacts with two distant atoms trapped in separated cavities. Through the measurement of the state of the first atom and the homodyne detection of the final output coherent light, the quantum state can be transferred into the second atom with a success probability of unity and a fidelity of unity. In addition, our scheme neither requires the high- Q cavity working in the strong coupling regime nor employs the single-photon quantum channel, which greatly relaxes the experimental requirements.
