Control of decoherence with no control

Jun Jing, Lian-Ao Wu

Published Sep 25, 2013• 30 citations

Abstract

A common philosophy in control theory is the control of disorder by order. Control of decoherence is no exception; strategies aimed at suppressing quantum decoherence adopt this point of view. Here we predict an anomalous phenomenon in open quantum systems-control of disorder by (even more) disorder. It is shown that suppression of decoherence can be achieved using the most disordered white noise field, specifically a white Poissonian noise field. This phenomenon seems to be another anomaly in quantum mechanics and may offer a new strategy in quantum control practices.

Control relaxation via dephasing: A quantum-state-diffusion study

Jun Jing, Ting Yu, Chi‐Hang Lam +2 more

Dynamical decoupling as a quantum control strategy aims at suppressing quantum decoherence adopting the popular philosophy that the disorder in the unitary evolution of the open quantum system caused by environmental noises should be neutralized by a sequence of ordered or well-designed external operations acting on the system. This work studies the solution of quantum-state-diffusion equations by mixing two channels of environmental noises, i.e., relaxation (dissipation) and dephasing. It is interesting to find in two-level and three-level atomic systems that a non-Markovian relaxation or dissipation process can be suppressed by a Markovian dephasing noise. The discovery results in an anomalous control strategy by coordinating relaxation and dephasing processes. Our approach opens an avenue of noise control strategy with no artificial manipulation over the open quantum systems.

Quantum Decoherence Control Theory and Dynamical Systems of Complex Systems

Jincheng Zhang

This paper explores the application of quantum decoherence theory to the control of complex classical systems. We propose a novel framework leveraging the probabilistic nature of decoherence to achieve precise control and prediction of complex system dynamics. The core mechanism involves stochastic control, where noise injection and coupling strength are optimized to steer the system towards a desired evolution path. Unlike traditional approaches to complex system analysis and control, this work introduces a fundamentally new perspective by translating core quantum concepts – specifically decoherence – into the domain of classical complexity. The theoretical development presents a method for managing and manipulating complex systems by understanding and mitigating the effects analogous to decoherence, offering potential advancements in fields ranging from chaos control to network dynamics. The central aim is to provide a robust and adaptable strategy for influencing the behavior of intricate systems, moving beyond purely deterministic models. ---

Quantum Decoherence Control Theory

Jincheng Zhang

This paper introduces a novel Quantum Decoherence Control Theory aimed at enhancing coherence times in quantum states through precise environmental noise management. The core mechanism relies on analyzing the impact of environmental noise on quantum states, utilizing quantum information theory and noise theory foundations to design targeted control strategies. Specifically, the theory proposes feedback control and quantum error correction techniques to suppress noise propagation and extend coherence times. Unlike existing approaches primarily relying on physical shielding and quantum error correction, this theory offers a more granular and adaptable method for mitigating decoherence, representing a significant advancement in quantum information processing. The theoretical framework is presented, outlining key equations and control parameters, and demonstrating the potential for achieving significantly longer coherence times under controlled noise conditions. This work lays the groundwork for future research into practical implementations of this theory.

Control of Open Quantum Systems

Christian

Known as decoherence, the unavoidable interaction of a quantum system with its surrounding environment is usually considered to be detrimental for quantum information processing. In this thesis the coherent, open loop control of such open systems is studied. Concepts from quantum control theory and the theory of open quantum system are adopted in order to fight decoherence and implement quantum gates in a noiseless manner. In particular, Lie algebraic methods and numerical optimization tools are used to investigate the control properties of a single spin interacting with a spin environment. We show that, independent of the size of the environment, every unitary transformation can be implemented on the system spin through a single control field. We proceed by investigating dynamical decoupling, a method to suppress the interactions with the environment, for finite- and for in- finite dimensional systems. We prove that every finite dimensional system can be protected from decoherence, even if the environment is infinite dimensional, whereas for noise described by a Lindblad master equation dynamical decoupling will never succeed. This will lead to a new method to distinguish decoherence from intrinsic noise terms. We further prove that not every infinite dimensional system can be protected from decoherence through dynamical decoupling. Afterwards we investigate dynamical decoupling of systems that are described by quadratic Hamiltonians, showing that such interactions can always be suppressed with two simple operations. In the last part we investigate the coherent control of a Lindblad master equation. We show that a strong noise process exhibiting a decoherence free subspace can substantially increase the number of unitary operations that can be implemented, allowing us to fully control parts of the system. Afterwards we develop a scheme to make Hamiltonians and Lindbladians commutative by adding an auxiliary system. The old, possibly non-commutative dynamics, is recovered through a non-selective measurement.

Noise Decoupling Decoherence Suppression Strategy for Markov Open Quantum Systems

Jing Zhang, Jianyong Li, Jianwu Wu

The problem of decoherence suppression for the general N-level Markov open quantum systems is studied. Here, the quantum feedback control strategy is presented for the quantum ensemble. In order to find the control Hamiltonians and the measured observables, the new concept of the noise decoupling decomposition for the su(N) Lie algebra is introduced. It is shown that some state variables of the coherence vector of the system density matrix can be completely decoupled from the environmental noises under the feedback control.

Dynamic Quantum Decoherence Control Theory and Quantum Defense

Jincheng Zhang

This paper presents a novel theoretical framework for dynamic control of quantum decoherence, specifically tailored for application within quantum communication and quantum computation defense mechanisms. The core of this work lies in the construction of a rigorous mathematical model of quantum decoherence, followed by the design of dynamic control algorithms utilizing established control theory principles. These algorithms are actively employed to suppress or manipulate decoherence, thereby bolstering the security of quantum information. We demonstrate a shift in perspective, framing decoherence control as a controllable systems problem, which provides a new approach to quantum defense. The theoretical foundations presented here offer a robust methodology for enhancing the resilience of quantum systems against environmental noise, a critical step towards practical, secure quantum technologies. Key areas explored include decoherence rate modeling, optimal control design, and adaptive control strategies. This research contributes significantly to the ongoing efforts in quantum information security and provides a practical roadmap for developing robust quantum defense protocols.
