The interaction between a quantum system and its surrounding environment underpins a variety of rich and interesting phenomena, ranging from dissipation and decoherence, to thermalization and quantum non-Markovianity. Understanding how to control and leverage these effects for information processing and thermodynamic tasks has become critical for the development of emerging quantum technologies.
Our research in this field, lead by Dr Graeme Pleasance and Prof Francesco Petruccione, focuses on several branches of open quantum systems theory, including:
- Development of non-perturbative techniques for treating strongly coupled and non-Markovian open systems.
- Thermodynamics of strongly coupled open quantum systems.
- Quantification and characterization of non-Markovian quantum processes.
- Digital simulation of Markovian and non-Markovian open quantum systems.
- Quantum collisional models.
- Quantum trajectory methods.
