Entanglement distance for arbitrary -qudit hybrid systems
Denise Cocchiarella, Stefano Scali, Salvatore Ribisi +3
The achievement of quantum supremacy boosted the need for a robust medium of quantum information. In this task, higher-dimensional qudits show remarkable noise tolerance and enhanc…

Entanglement distance for an arbitrary state of M qubits
Denise Cocchiarella, Stefano Scali, Salvatore Ribisi +3
We propose a measure of entanglement that can be computed for any pure state of an -qubit system. The entanglement measure has the form of a distance that we derive from an adap…

Entanglement estimation in non-optimal qubit states
Stefano Scali, Roberto Franzosi
In the last years, a relationship has been established between the quantum Fisher information (QFI) and quantum entanglement. In the case of two-qubit systems, all pure entangled s…
