Collective decoherence of cold atoms coupled to a Bose-Einstein condensate
M. A. Cirone, G. De Chiara, G. M. Palma +1
We examine the time evolution of cold atoms (impurities) interacting with an environment consisting of a degenerate bosonic quantum gas. The impurity atoms differ from the environm…
A deeper insight into quantum state transfer from an information flux viewpoint
C. Di Franco, M. Paternostro, G. M. Palma
We use the recently introduced concept of information flux in a many-body register in order to give an alternative viewpoint on quantum state transfer in linear chains of many spin…
Extraction of Singlet States from Noninteracting High-Dimensional Spins
Francesco Ciccarello, Mauro Paternostro, Myungshik S. Kim +1
We present a scheme for the extraction of singlet states of two remote particles of arbitrary quantum spin number. The goal is achieved through post-selection of the state of inter…
Information-flux approach to multiple-spin dynamics
C. Di Franco, M. Paternostro, G. M. Palma +1
We introduce and formalize the concept of information flux in a many-body register as the influence that the dynamics of a specific element receive from any other element of the re…
