Abstract :
In this paper, we study the chaotic dynamics of an optomechanical systems coupled to a non-Markovian environment. The master equation of the system is derived beyond the Markovian approximation and the maximum Lyapunov exponent is employed to quantify the generation of chaos. In contrast to the majority of existing studies on chaos generation in optomechanical systems, our work highlights that the influence exerted by the properties of the environment can be of equivalent significance to that of the system parameters, and in certain cases, the environmental parameters may be even more important. The numerical results show that the memory time and central frequency of the environment play crucial roles in the generation of chaos, and they can even determine whether chaos occurs. In addition, we also investigate the influence of system parameters and compare them with the environmental parameters. We hope the results presented in this paper open a new direction for the research on chaos generation and attract more attentions on the influence of the properties of environments.

Abstract :
In this paper, we study the Schr & ouml;dinger cat state transfer in a quantum optical version of Newton's cradle in a non-Markovian environment. Based on a non-Markovian master equation, we show that the cat state can be transferred purely through the memory effect of the nonMarkovian common environment, even without any direct couplings between neighbor cavities. The mechanism of the environment-induced cat state transfer is analyzed both analytically and numerically to demonstrate that the transfer is a unique phenomenon in a non-Markovian regime. From this example, the non-Markovian environment is shown to be qualitatively different from the Markovian environment, reflected by the finite versus zero residue coherence. Besides, we also show the influence of environmental parameters is crucial for the transfer. We hope the cat state transfer studied in this work may shed more light on the fundamental difference between non-Markovian and Markovian environments.

Abstract :
Noise is often considered as the biggest enemy of maintaining quantum coherence. However, in this paper, we show a scheme to protect quantum coherence by introducing extra noise. To be specific, we study an atom coupled to a single mode cavity (Jaynes-Cummings model) with two noises. One is from the cavity leakage, the other is from the stochastic atom-cavity coupling. Based on the non-Markovian dynamical equation, we show the quantum coherence can be protected by introducing the noise in the atom-cavity coupling. We study four different types of noises and show their performance on the coherence protection. We also analytically reveal the mechanism of the quantum coherence protection, namely the high frequency noise can freeze the dynamics thus protect coherence. Last but not least, a mixture of different types of noises (hybrid noise) is studied. We show the mixture can lower the performance of the coherence protection scheme and provide an explanation. We hope the results presented here may attract more attention on protecting quantum coherence by utilizing noise. © 2024 Astro Ltd.

Abstract :
In this paper, the higher energy levels of the transmon qubit are taken into consideration to investigate the continuous variable entanglement generation between the transmon qubit and the single-mode cavity. Based on the framework of cavity Quantum Electrodynamics (QED), the authors show the entanglement generation depends on the driving field intensity, coupling strength, cavity field frequency, and qubit frequency. The numerical results show that strong entanglement can be generated by properly tuning these parameters. It is hoped that the results presented in this paper may lead to a better understanding of quantum entanglement generation in cavity QED systems and provide new perspectives for further research in quantum information processing. This study investigates continuous variable entanglement between a transmon qubit and a cavity in Quantum Electrodynamics (QED). It examines the effects of driving field intensity, coupling strength, and frequency on entanglement, providing insights for quantum information processing by demonstrating control over strong entanglement in cavity QED systems.image

Abstract :
In this paper, we propose a one-step scheme for generating a multiqubit controlled-controlled-Z (CCZ) gate based on Rydberg atoms where an amplitude-modulated field is employed to induce Rydberg antiblockade. The Rydberg atoms can form a Rabi oscillation between the ground state and the collective excited state effectively, so a one-step three-qubit CCZ gate can be easily achieved through a Rabi cycle. Numerical simulation results show that the scheme has a high fidelity and robustness against errors which are caused by parameter errors, intrinsic errors, and atomic decays. Therefore, we hope that this scheme will enable fast and robust quantum computing in the near future.

Abstract :
Chaos is important in nonlinear science and promotes the development of fundamental studies, such as neural networks, extreme event statistics, and electron transport. In this paper, a theoretical scheme for generating dynamical chaos in a Fabry-Perot cavity with two-level atoms is investigated. Through the injection of atoms, controllable chaos of the cavity and mechanical oscillator is achieved simultaneously by the external laser field. The trajectory and the maximal Lyapunov exponent that characterize the properties of the chaos could be optimized by adjusting the coupling constant, driving field, injection of atoms, the frequency of the cavity, and the frequency of the mechanical oscillator. This study provides a new idea to manipulate the cavity and mechanical chaos assisted by two level atoms. It is hoped that the results presented can benefit controllable chaos generation and its applications.

Abstract :
The dynamics of chaos in quantum systems has attracted much interest in connection with the fundamental aspects of quantum mechanics. We study the chaotic dynamics of both the excitonic mode and the cavity mode in a microcavity containing a quantum well driven by an external field. We investigate how the chaotic dynamics is influenced by the frequencies of the exciton and the cavity, the coupling constant between the exciton and cavity, the Coulomb interaction between excitons, and the response of the exciton to the cavity and the external field. We show that chaos can be generated synchronously in both the cavity and the excitonic mode by choosing appropriate parameters. Moreover, this kind of chaos can be controlled by the coupling constant, the strength of the interaction between excitons, the external field, the response of the excitons to the cavity, and the detuning between the cavity field and the excitonic field. The present study may have applications in chaos-based neural networks and extreme event statistics.

Abstract :
Noise is often considered as the biggest enemy of maintaining quantum entanglement. However, in this paper, it shows quantum entanglement can be protected by introducing extra noises to a quantum system. As an example, the dynamics of a two-qubit system coupled to a cavity is studied under the influence of three noises, a quantized noise from the leakage of the cavity and two classical noises in the couplings between the two-qubit system and the cavity. The master equation beyond the Markov approximation is derived and the mechanism of the entanglement protection is analyzed in a special case with analytical solutions. In short, the entanglement loss caused by the dissipation to the bath might be weaken by introducing high-frequency classical noises properly. The numerical simulations not only confirm the feasibility of protecting entanglement by noises but also reveal that the properties of the classical noises have a significant impact on the performance of the entanglement protection. Due to inevitable interaction with noisy environments, quantum systems often lose their entanglement quickly. Since noise is ubiquitous, an intriguing question arises: Is it possible to combat a noisy environment with its own weapon, namely, noise? This article explores the suppression of entanglement loss caused by a noisy environment through properly introducing additional classical noises.image
