Entanglement gain in measurements with unknown results
Margherita Zuppardo, Ray Ganardi, Marek Miller +2
We characterise non-selective global projective measurements capable of increasing quantum entanglement between two particles. We show that non-selective global projective measurem…
Genuine -partite entanglement without -partite correlation functions
Minh Cong Tran, Margherita Zuppardo, Anna de Rosier +4
A genuinely -partite entangled state may display vanishing -partite correlations measured for arbitrary local observables. In such states the genuine entanglement is noticeab…
Revealing non-classicality of inaccessible objects
Tanjung Krisnanda, Margherita Zuppardo, Mauro Paternostro +1
Some physical objects are hardly accessible to direct experimentation. It is then desirable to infer their properties based solely on the interactions they have with systems over w…
Excessive distribution of quantum entanglement
Margherita Zuppardo, Tanjung Krisnanda, Tomasz Paterek +6
We classify protocols of entanglement distribution as excessive and non-excessive ones. In a non-excessive protocol, the gain of entanglement is bounded by the amount of entangleme…
Cavity-aided quantum parameter estimation in a bosonic double-well Josephson junction
M. Zuppardo, J. P. Santos, G. De Chiara +3
We describe an apparatus designed to make non-demolition measurements on a Bose-Einstein condensate (BEC) trapped in a double-well optical cavity. This apparatus contains, as well…
