Standard super-activation for Gaussian channels requires squeezing
Daniel Lercher, Géza Giedke, Michael M. Wolf
The quantum capacity of bosonic Gaussian quantum channels can be non-additive in a particularly striking way: a pair of such optical-fiber type channels can individually have zero…
Pairing in fermionic systems: A quantum information perspective
Christina V. Kraus, Michael M. Wolf, J. Ignacio Cirac +1
The notion of "paired" fermions is central to important condensed matter phenomena such as superconductivity and superfluidity. While the concept is widely used and its physical me…
Entanglement in fermionic systems
Mari-Carmen Bañuls, J. Ignacio Cirac, Michael M. Wolf
The anticommuting properties of fermionic operators, together with the presence of parity conservation, affect the concept of entanglement in a composite fermionic system. Hence di…
Dividing Quantum Channels
Michael M. Wolf, J. Ignacio Cirac
We investigate the possibility of dividing quantum channels into concatenations of other channels, thereby studying the semigroup structure of the set of completely-positive trace-…
Extremality of Gaussian quantum states
Michael M. Wolf, Geza Giedke, J. Ignacio Cirac
We investigate Gaussian quantum states in view of their exceptional role within the space of all continuous variables states. A general method for deriving extremality results is p…
Quantum states on Harmonic lattices
Norbert Schuch, J. Ignacio Cirac, Michael M. Wolf
We investigate bosonic Gaussian quantum states on an infinite cubic lattice in arbitrary spatial dimensions. We derive general properties of such states as ground states of quadrat…
