Transfer and routing of Gaussian states through quantum complex networks with and without community structure
Markku Hahto, Johannes Nokkala, Guillermo García-Pérez +2
The goal in quantum state transfer is to avoid the need to physically transport carriers of quantum information. This is achieved by using a suitably engineered Hamiltonian that in…

Remote polarization entanglement generation by local dephasing and frequency upconversion
S. Hamedani Raja, G. Karpat, E. -M. Laine +4
We introduce a scheme for remote entanglement generation for the photon polarization. The technique is based on transferring the initial frequency correlations to specific polariza…

Misbelief and misunderstandings on the non--Markovian dynamics of a damped harmonic oscillator
S. Maniscalco, F. Intravaia, J. Piilo +1
We use the exact solution for the damped harmonic oscillator to discuss some relevant aspects of its open dynamics often mislead or misunderstood. We compare two different approxim…
