Estimation of quantum channels with finite resources
Markus A. Cirone, Aldo Delgado, Dietmar G. Fischer +3
We investigate the problem of determining the parameters that describe a quantum channel. It is assumed that the users of the channel have at best only partial knowledge of it and…
Channel Estimation with Noisy Entanglement
Thorsten C. Bschorr, Dietmar G. Fischer, Matthias Freyberger
We analyze the Pauli-channel estimation with mixed nonseparable states. It turns out that within a specific range entanglement can serve as a nonclassical resource. However, this r…
Enhanced Estimation of a Noisy Quantum Channel Using Entanglement
Dietmar G. Fischer, Holger Mack, Markus A. Cirone +1
We discuss the estimation of channel parameters for a noisy quantum channel - the so-called Pauli channel - using finite resources. It turns out that prior entanglement considerabl…
