摘要

We apply the quantum jump approach to address the statistics of work in a driven two-level system coupled to a heat bath. We demonstrate how this question can be analyzed by counting photons absorbed and emitted by the environment in repeated experiments. We find that the common nonequilibrium fluctuation relations are satisfied identically. The usual fluctuation-dissipation theorem for linear response applies for weak dissipation and/or weak drive. We point out qualitative differences between the classical and quantum regimes.

Non-Markovian Steady States of a Driven Two-Level System

Andreas Ask, Goran Johansson

Summary: The paper investigates the steady state behavior of an open quantum system in a non-Markovian environment. By studying a driven two-level system in a semi-infinite waveguide, it is found that non-Markovian states exhibit exotic behaviors such as population inversion and steady-state coherence beyond what is possible in the Markovian regime.

Extracting the lifetime of a synthetic two-level system

Gabriel Margiani, Sebastian Guerrero, Toni L. Heugel, Christian Marty, Raphael Pachlatko, Thomas Gisler, Gabrielle D. Vukasin, Hyun-Keun Kwon, James M. L. Miller, Nicholas E. Bousse, Thomas W. Kenny, Oded Zilberberg, Deividas Sabonis, Alexander Eichler

Summary: The Kerr Parametric Oscillator (KPO) is a nonlinear resonator system that behaves like a synthetic two-level system. It switches between two states in phase space via fluctuating trajectories, instead of moving along a straight path. To address the issue, several rate counting methods are compared to estimate the lifetime of the levels. It is found that the peak in the Allan variance of fluctuations can also be used to determine the lifetime of the levels. This work provides a foundation for characterizing KPO networks in simulated annealing, where accurate determination of state lifetime is crucial.

Controllable dynamics of a dissipative two-level system

Wei Wu, Ze-Zhou Zhang

Summary: The study shows that the decay rate of a two-level system interacting with a dissipative environment can be significantly suppressed by introducing an ancillary degree of freedom, offering an alternative way to combat decoherence and achieve controllable quantum dissipative dynamics.

Unitary evolution for a two-level quantum system in fractional-time scenario

D. Cius, L. Menon Jr, M. A. F. dos Santos, A. S. M. de Castro, Fabiano M. Andrade

Summary: In this paper, we demonstrate how to map the nonunitary time-evolution operator in a unitary one by considering a dynamical Hilbert space with a time-dependent metric operator. Three examples of Hamiltonian operators and their corresponding unitary dynamics obtained from the solutions of FTSE are also discussed.

Entanglement and coherence in a system of two atoms in the presence of Kerr medium and field dissipation

K. Berrada, S. Abdel-Khalek, A. Alkaoud, H. Eleuch

Summary: In this paper, we qualitatively investigate the quantum entanglement and coherence in a quantized field with two atoms coupled to a Kerr medium and Ising interaction. By examining the A-A concurrence, von Neumann entropy, l1 norm coherence, and Mandel's parameter, we explore the effects of atom-atom interaction and field nonlinearity on the dynamics of quantumness measures. We also illustrate the relations between information quantifiers in the presence and absence of field dissipation.

Engineering entanglement, geometric phase, and quantum Fisher information of a three-level system with energy dissipation

S. Abdel-Khalek, S. M. Abo-Dahab, Mahmoud Ragab, Muhyaddin Rawa, Hijaz Ahmad

Summary: This study examines the quantum Fisher information (QFI), entanglement, and geometric phase of a three-level atom interacting with a quantized field mode in a specific configuration, and investigates the correlations between these statistical quantities. The findings suggest that the QFI is highly sensitive to the effects of time-dependent coupling and energy dissipation.

First law of quantum thermodynamics in a driven open two-level system

Adrian Juan-Delgado, Aurelia Chenu

Summary: The paragraph discusses the challenges of assigning variations of internal energy into heat or work contributions, as these properties are dependent on trajectory. Various proposals for open quantum systems with arbitrary dynamics have been put forward. It focuses on nonequilibrium thermodynamics of a two-level system, exploring two definitions motivated by classical work or heat.

Hybrid level anharmonicity and interference-induced photon blockade in a two-qubit cavity QED system with dipole-dipole interaction

C. J. Zhu, K. Hou, Y. P. Yang, L. Deng

Summary: We theoretically studied a quantum destructive interference (QDI)-induced photon blockade in a two-qubit driven cavity quantum electrodynamics system with dipole-dipole interaction (DDI). By introducing DDI, the condition for photon blockade can be significantly improved, providing a novel platform for generating single photons.

A Hybrid Health Monitoring Approach for Aircraft Flight Control Systems With System-Level Degradation

Yihan Guo, Cunbao Ma, Zhengdong Jing

Summary: This article proposes a novel hybrid health monitoring approach to monitor the system-level degradation of aircraft flight control systems (FCSs). The approach utilizes nonlinear degradation signal extraction and a jump Markov autoregressive exogenous (JMARX) system to establish the FCS system-level degradation model. The effectiveness of the approach is validated through a practical flight experiment.

A computational approach for a two-parameter singularly perturb e d system of partial differential equations with discontinuous coefficients

K. Aarthika, V. Shanthi, Higinio Ramos

Summary: This work aims to obtain a numerical approximation to the solution of a two-parameter singularly perturbed convection-diffusion-reaction system of partial differential equations with discontinuous coefficients. The proposed approach combines a central finite-difference method and an implicit Euler scheme, and computational experiments confirm the theoretical findings.

Time glass: A fractional calculus approach

R. C. Verstraten, R. F. Ozela, C. Morais Smith

Summary: This study provides a description of time glasses using fractional calculus methods, introducing an exactly solvable effective theory with a continuous parameter to describe the transition from liquid to normal glass, time glass, and the Gardner phase. The phenomenological description with a fractional Langevin equation is linked to a microscopic model within the framework of a generalized Caldeira-Leggett model.

Influence of the dissipation on the N-level atom interacting with a two two-level atoms in presence of qubit-qubit interaction

S. Abdel-Khalek, Hashim M. Alshehri, E. M. Khalil, A-S F. Obada

Summary: This study investigates the interaction of two qubits and an N-level atom based on su(2) Lie algebra, in the presence of qubit-qubit interaction and a dissipation term. The effects of these interactions on the system dynamics are discussed in detail, along with the calculation and analysis of observable operators, population inversion, linear entropy, and concurrence as a measure of entanglement. The roles of the number of levels, qubit-qubit coupling parameter, and dissipation rate on these quantities are explored, including the sudden birth and sudden death of entanglement phenomena with and without the dissipation term.

Off-diagonal electron-phonon coupling effects on two-level system dynamics

Leonard Ruocco, Mona Berciu, Jeff F. Young

Summary: Electromagnetically coupled two-level systems have been studied for their role in quantum information processing applications in condensed matter. In this study, the influence of phonon excitations on the electromagnetic response of these systems is investigated, including the effects of phonon-assisted transitions and lifetime broadening. The results reveal the impact of the phonon frequency distribution on the spectral weight of the zero-phonon transition and the phonon sidebands, as well as the broadening of the zero-phonon line due to nondiagonal electron-phonon coupling. This study emphasizes the importance of considering both forms of electron-phonon coupling in the analysis of these systems, and provides a formalism that can be extended to higher orders of coupling and realistic phonon spectral functions.

Characterization of a Driven Two-Level Quantum System by Supervised Learning

Raphael Couturier, Etienne Dionis, Stephane Guerin, Christophe Guyeux, Dominique Sugny

Summary: This article investigates the use of supervised learning to describe a two-level quantum system under an external time-dependent drive. The approach is applied to bang-bang control and the estimation of offset and final distance to a target state. A neural network is used to interpolate the mapping between offset and distance. Different neural network algorithms are tested, showing high precision in reproducing the mapping in the direct case while facing obstacles in the indirect case. The limits of the estimation procedure and the physical relevance of the results are discussed.

Dimensional control of tunneling two-level systems in nanoelectromechanical resonators

T. Kamppinen, J. T. Makinen, V. B. Eltsov

Summary: At low temperatures, tunneling two-level systems often impact the performance of devices, and experimental verification is still needed for extending the theoretical description to small dimensions. The authors provide support through their investigation of nanoelectromechanical resonators. The study concludes that the geometry of the resonator plays a crucial role in managing the coupling of tunneling two-level systems with phonons.
