Quantum Resources and Information Laboratory

Main research interest of the group are general quantum resource theories and their applications for quantum technology.

Quantum resource theories provide a strong mathematical framework for studying general quantum phenomena, such as quantum entanglement and coherence. Quantum thermodynamics can also be formulated as a resource theory. Quantum entanglement and coherence play an important role in quantum technology, most importantly in quantum communication and computation. Our team studies the role of general quantum resources for quantum technologies, investigating already existing protocols for quantum communication and computation. Since entanglement is a very fragile feature and quickly disappears in the presence of noise, we also aim to develop new quantum protocols which do not require entanglement, but are based on other types of quantum resources, such as quantum coherence.

Quantum Coherence and Entanglement for Quantum Technology

Project Leader: Alexander Streltsov , PhD Project period: 01.06.2019 - 31.05.2022
Project funding: FIRST TEAM Foundation for Polish Science
Project description:

Aim of the project is to provide a solid theoretical background for nonclassical phenomena, such as quantum coherence and entanglement, with particular focus on their role in quantum technology. We aim to find new quantum protocols which make use of these fundamental quantum features, and to study the thermodynamical limitations of quantum communication protocols.
