Approximating open quantum system dynamics in a controlled and efficient way: A microscopic approach to decoherence
Giulia Gualdi, Christiane P. Koch
We demonstrate that the dynamics of an open quantum system can be calculated efficiently and with predefined error, provided a basis exists in which the system-environment interact…

Entanglement quantification by local unitaries
A. Monras, G. Adesso, S. M. Giampaolo +3
Invariance under local unitary operations is a fundamental property that must be obeyed by every proper measure of quantum entanglement. However, this is not the only aspect of ent…

Characterizing and Quantifying Frustration in Quantum Many-Body Systems
S. M. Giampaolo, G. Gualdi, A. Monras +1
We present a general scheme for the study of frustration in quantum systems. We introduce a universal measure of frustration for arbitrary quantum systems and we relate it to a cla…
