Activating optomechanical entanglement
Laura Mazzola, Mauro Paternostro
We propose an optomechanical setup where the activation of entanglement through the pre-availability of non-classical correlations can be demonstrated experimentally. We analyse th…
Generalized Coherent States and Extremal Positive Operator Valued Measures
Teiko Heinosaari, Juha-Pekka Pellonpää
We present a correspondence between positive operator valued measures (POVMs) and sets of generalized coherent states. Positive operator valued measures describe quantum observable…
Informationally complete joint measurements on finite quantum systems
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
We show that there are informationally complete joint measurements of two conjugated observables on a finite quantum system, meaning that they enable to identify all quantum states…
Nonlocal memory effects in the dynamics of open quantum systems
Elsi-Mari Laine, Heinz-Peter Breuer, Jyrki Piilo +2
We explore the possibility to generate nonlocal dynamical maps of an open quantum system through local system-environment interactions. Employing a generic decoherence process indu…
Experimental control of the transition from Markovian to non-Markovian dynamics of open quantum systems
Bi-Heng Liu, Li Li, Yun-Feng Huang +5
Realistic quantum mechanical systems are always exposed to an external environment. The presence of the environment often gives rise to a Markovian process in which the system lose…
Quantum Tomography under Prior Information
Teiko Heinosaari, Luca Mazzarella, Michael M. Wolf
We provide a detailed analysis of the question: how many measurement settings or outcomes are needed in order to identify a quantum system which is constrained by prior information…
