Bayesian estimation of one-parameter qubit gates
Berihu Teklu, Stefano Olivares, Matteo G A Paris
We address estimation of one-parameter unitary gates for qubit systems and seek for optimal probes and measurements. Single- and two-qubit probes are analyzed in details focusing o…
Distilling entanglement from Fermions
M. Keyl
Since Fermions are based on anti-commutation relations, their entanglement can not be studied in the usual way, such that the available theory has to be modified appropriately. Rec…
Tripartite entanglement transfer from flying modes to localized qubits
Federico Casagrande, Alfredo Lulli, Matteo G. A. Paris
We investigate the process of entanglement transfer from a three-mode quantized field to a system of three spatially separated qubits each one made of a two-level atom resonantly c…
Robust strategies for lossy quantum interferometry
Lorenzo Maccone, Giovanni De Cillis
We give a simple multiround strategy that permits to beat the shot noise limit when performing interferometric measurements even in the presence of loss. In terms of the average ph…
Thermal states of the Kitaev honeycomb model: a Bures metric analysis
Damian F. Abasto, Paolo Zanardi
We analyze the Bures metric over the canonical thermal states for the Kitaev honeycomb mode. In this way the effects of finite temperature on topological phase transitions can be s…
Optimal quantum estimation in spin systems at criticality
Carmen Invernizzi, Michael Korbman, Lorenzo Campos Venuti +1
It is a general fact that the coupling constant of an interacting many-body Hamiltonian do not correspond to any observable and one has to infer its value by an indirect measuremen…
