Advances in Quantum Control Theory

Daoyi Dong

Quantum control theory is a new interdiscipline, which mainly studies the control of quantum states for systems in the microworld. First, quantum control theory is elicited through quantum information theory. Then the research contents and characteristics of quantum control theory and measurement theory in quantum control are expounded. Current research of quantum control theory is also summarized. And last, advanced research on quantum control theory is proposed.

This paper presents a novel theoretical framework for quantum state evolution, termed the Dynamic Quantum State Theory (DQST). We establish a dynamic state evolution model, demonstrating the ability to analyze quantum state transitions and leverage these transitions for controlled quantum device operation. The core of this theory lies in the design of an automated control mechanism predicated on the observed dynamics of the quantum state. This approach offers a potential pathway toward achieving "self-adaptive" control of quantum devices, representing a significant advance over traditional approaches. The paper outlines the model's key components, explains the underlying mathematical principles, and provides a preliminary analysis of its capabilities. We demonstrate through simplified examples how the DQST framework can be used to model and control quantum transitions, highlighting its potential for advanced quantum control. The proposed mechanism is presented as a key differentiator, offering a fundamentally different approach to quantum device optimization.
