The inverse eigenvalue problem for quantum channels
Michael M. Wolf, David Perez-Garcia
Given a list of n complex numbers, when can it be the spectrum of a quantum channel, i.e., a completely positive trace preserving map? We provide an explicit solution for the n=4 c…

Non-disturbing quantum measurements
Teiko Heinosaari, Michael M. Wolf
We consider pairs of quantum observables (POVMs) and analyze the relation between the notions of non-disturbance, joint measurability and commutativity. We specify conditions under…

Quantum memory for entangled two-mode squeezed states
K. Jensen, W. Wasilewski, H. Krauter +7
A quantum memory for light is a key element for the realization of future quantum information networks. Requirements for a good quantum memory are (i) versatility (allowing a wide…
