The susceptibility of quantum information to environmental disturbances and experimental inaccuracies poses a challenge to usable quantum information processors. Quantum error correction (QEC) - a method for shielding quantum information from noise - is crucial for the realization of universally applicable and scalable quantum computation.

In my research, I developed a new bosonic quantum code that could outperform many other quantum codes and that might be implemented in future quantum devices.

In realistic quantum systems, interactions with the environment play a crucial role, giving rise to decoherence, dissipation processes, and the decay of quantum information.

Efficiently simulating the dynamics of many-body driven-dissipative systems is a key requirement to understanding time-dependent processes such as quantum gates as well as to investigating emergent phenomena such as dissipative phase transitions, criticality, and quantum chaos.

I am actively working on new variational methods to efficiently simulate the dynamics of bosonic many-body driven-dissipative systems. This also enables the study of time-dependent phenomena in bosonic codes.

Quantum Information Theory forms the theoretical foundation for quantum computation and communication, exploring the unique potential of quantum systems for information processing.

My current focus lies in studying the capacity of quantum channels under realistic noise conditions, including photon loss and dephasing. This research provides crucial insights for harnessing the true power of quantum technologies in practical applications.

Fault-tolerant quantum computing represents a visionary approach to quantum computing, striving to execute complex quantum computations reliably, even in the face of inevitable quantum errors. By utilizing sophisticated error correction codes and architectures, fault-tolerant quantum computing aims to overcome the fragility of quantum information and pave the way for the realization of large-scale, practical quantum systems.

As an active researcher in this field, I am deeply committed to advancing our understanding and pushing the boundaries of this transformative technology.

I have a strong interest in various fields of research in quantum science. This includes quantum computing, quantum information theory, practical applications of quantum theory, and the foundational principles of quantum mechanics. I find each of these areas fascinating and believe that they offer great potential for advancing our understanding of the world around us.
