Abstract

The traditional quantum control theory focuses on linear quantum system. Here we show the effect of nonlinearity on quantum control of a two-level system, we find that the nonlinearity can change the controllability of quantum system. Furthermore, we demonstrate that the Lyapunov control can be used to overcome this uncontrollability induced by the nonlinear effect.

Based on Nonlinear Control Theory: Quantum System Regulation

Jincheng Zhang

This paper investigates the application of nonlinear control theory to the precise regulation of quantum systems. Traditional control methods often struggle with the inherent complexities and sensitivities of quantum systems. This work proposes a novel approach leveraging nonlinear control techniques to directly manipulate quantum state evolution. The core claim is that by designing appropriate nonlinear control signals, it is possible to achieve precise control over quantum system dynamics. The central mechanism involves the targeted modulation of quantum motion using these nonlinear signals, ultimately enabling accurate state control. This approach overcomes the limitations of linear control methods and offers a fundamentally new way to interact with and manage quantum systems. We explore the theoretical framework, mathematical formulations, and potential applications of this approach, focusing on the design and implementation of control strategies for quantum systems. The presented methodology provides a robust and adaptable framework for quantum system regulation, promising significant advancements in quantum technologies.

Optimal Lyapunov quantum control on two-level systems: convergence and extended techniques

L. C. Wang, S. C. Hou, Xun Yi +2 more

Taking a two-level system as an example, we show that a strong control field may enhance the efficiency of optimal Lyapunov quantum control in [Hou et al., Phys. Rev. A \textbf{86}, 022321 (2012)] but could decrease its control fidelity. A relationship between the strength of the control field and the control fidelity is established. An extended technique, which combines free evolution and external control, is proposed to improve the control fidelity. We analytically demonstrate that the extended technique can be used to design a control law for steering a two-level system exactly to the target state. In such a way, the convergence of the extended optimal Lyapunov quantum control can be guaranteed.

Quantum-Enhanced Non-Linear Control of Dynamical Systems

Jincheng Zhang

This paper investigates the potential of quantum computation to revolutionize the control of dynamical systems. Dynamical systems, characterized by their complex, nonlinear behavior, pose significant challenges in various fields, including engineering, physics, and biology. Traditional control methods often struggle to effectively manage these systems due to their sensitivity to initial conditions and inherent unpredictability. We propose a novel approach leveraging quantum entanglement and superposition to enhance dynamical system control, specifically focusing on improving stability and predictability through precise manipulation of the system's state. This work explores a quantum algorithm designed to achieve this enhancement, demonstrating its potential for significantly improving the performance of complex systems. The core mechanism involves quantum state manipulation to achieve a level of precision unattainable by classical approaches, ultimately leading to more stable and predictable behavior.

Identification and control of quantum systems

Zhengui Xue, Hai Lin, Tong Heng Lee

This paper aims at finding the real-valued dynamics that is equivalent to the Schrödinger equation and then implementing quantum control by making use of the well developed classical control theory. Firstly, pure state identification approaches are presented for two-level, three-level and n-level systems, respectively. Secondly, based on the discussions on the pure state identification, real-valued dynamics that are equivalent to the Schrödinger equations are deduced for both two-level and three-level systems. Finally, a control strategy based on Lyapunov approach is proposed by making use of the obtained real-valued dynamics. Different from the existing Lyapunov control based on the Schrödinger equation, the proposed control strategy can achieve state convergence to its goal state without any constraints on the internal Hamiltonian. Simulation results are included to demonstrate the effectiveness of the approach.

Time-delay effects and simplified control fields in quantum Lyapunov control

X. X. Yi, S. L. Wu, Chunfeng Wu +2 more

Lyapunov-based quantum control has the advantage that it is free from the measurement-induced decoherence and it includes the instantaneous information of the system in the control. The Lyapunov control is often confronted with time delay in the control fields and difficulty in practical implementations of the control. In this paper, we study the effect of time delay on the Lyapunov control and explore the possibility of replacing the control field with a pulse train or a bang–bang signal. The efficiency of the Lyapunov control is also presented through examining the convergence time of the system. These results suggest that the Lyapunov control is robust against time delay, easy to realize and effective for high-dimensional quantum systems.
