The interaction between quantum systems and their environment generally causes the loss of quantum properties, such as entanglement, and destroys quantum superpositions. This problem has both fundamental and applicative interest. Indeed, on the one hand decoherence, i.e., the loss of quantum coherence due to the interaction with the environment, has been proposed as a possible explanation of the quantum-classical transition and, on the other hand, new quantum technologies such as quantum computers can be built only if we find ways to win the battle against decoherence.

The research of the Open Quantum Systems and Entanglement group focuses on the theory of open quantum systems, i.e., systems interacting with their environment, and in particular on non-Markovian quantum processes. The major research topics of the group are: dynamics of entanglement and quantum discord in the presence of structured environments, reservoir engineering for quantum technologies, quantum Brownian Motion, decoherence control and the quantum Zeno effect.

Sabrina Maniscalco was born in Mazara del Vallo, Italy, in 1974. She obtained her MSc (specialization in Theoretical Physics) in 1999 and her PhD in Physics in 2004, both from the University of Palermo. She has been a PostDoc at the University St. Kliment Ohridski in Sofia, Bulgaria, and at the University of KwaZulu-Natal in Durban, South Africa. In 2005 she joined the University of Turku, Finland, as a senior researcher, first, and then as an Adjunt Professor. Since January 2009 she is leading the Open Quantum Systems and Entanglement (OQSE) group.

She joined the Heriot-Watt University in January 2011 and continues to lead the OQSE.
