Quantum Zealous Fully Probabilistic Framework for Anticipating and Controlling Quantum Systems, (QuaCoq)

Lead Research Organisation: Aston University
Department Name: College of Engineering and Physical Sci

Abstract

QuaCoq will explore new ways of using external signals to actively influence and manipulate the evolving state of quantum systems at the level of atoms, molecules and particles. By accurately controlling the interactions between the quantum components of the system, experimentalists will be able to evolve the system towards some desired outcome and create new quantum states that can be used for tests of fundamental physics and quantum technological applications. However, the increased complexity, imperfections and detrimental effects of the surroundings of many-body quantum systems are hindering advances of the current state of the art quantum control. Accordingly, QuaCoq will aim at developing a probabilistic feedback control framework that acknowledges the probabilistic and uncertain nature of atomic-scale physical systems resulting in accurate manipulation of their dynamics. The proposed framework will develop explorative randomised control strategies that address additional challenges of an open quantum system including multiple context operations, and lags between the time at which a control signal is received and the associated system state is modified. It will develop the theory and methods of controlling many body quantum systems and provide new insights that could lead to significant evolution in new quantum technologies that will promote transformational advances in secure communications, information technology and high precision sensors.

Description This project made important discoveries in the field of quantum control theory. The team developed a new approach to designing quantum controllers that can effectively control the probabilistic nature, irreversible character, and dissipation effects of quantum systems. The team achieved their objectives of developing a control theory based on the probabilistic description of quantum systems and developing probabilistic models that can reproduce the stochastic dynamics of a quantum system.

The project's significant achievement is the development of a fully probabilistic control framework for designing randomised controllers. This framework provides a foundation for further research and development of control theory based on the probabilistic description of quantum systems.

Overall, this project has made important strides in understanding and controlling quantum systems. The findings from this project could have applications in fields such as quantum computing, materials science, and chemical engineering, among others.
Exploitation Route The findings from this project provide a solid foundation for further research and development of control theory based on the probabilistic description of quantum systems. Researchers in the field of quantum control theory can use the probabilistic control framework and probabilistic models developed in this project to explore new ways of controlling many-body quantum systems and to develop new quantum controllers that address the challenges of switching quantum dynamics and dynamics with state and control input delays.

Description The impact of the project will principally be: 1. The development of a novel enabling solution for the probabilistic control of quantum systems. This underpinning methodology will open new avenues for research in the control of such systems. 2. Enable the development of new quantum technologies across the UK and worldwide. 3. Establish UK scientific and technological leadership and a core of trained researchers within the UK who can drive the quantum probabilistic control developments forward and advance its realisation.
