Quantum information and open quantum systems theories study how quantum mechanics can be used to study information processing and how quantum systems behave under environmental influence. While quantum information is key to technologies like quantum computing, open quantum systems theory examines how environments cause decoherence. Together, they seek to realize quantum technologies while overcoming environmental challenges.
Our research group focuses on the theory of open quantum systems, with an emphasis on non-Markovian quantum processes and quantum synchronization. We develop models to understand how memory affect dynamics beyond the Markovian approximation. In particular, we study how non-Markovianity can be leveraged to enhance coherence and control in quantum systems. We also investigate synchronization phenomena in coupled quantum systems such as qubits, identifying conditions under which quantum systems exhibit collective behavior. These studies potentially contribute to the establishment of robust quantum technologies, such as quantum communication networks. Our goal is to provide theoretical tools that improve performance and resilience against noise in practical quantum devices.
