Holographic Inequalities and Entanglement of Purification
Ning Bao, Illan F. Halpern
We study the conjectured holographic duality between entanglement of purification and the entanglement wedge cross-section. We generalize both quantities and prove several informat…

Asymptotic Charges Cannot Be Measured in Finite Time
Raphael Bousso, Venkatesa Chandrasekaran, Illan F. Halpern +1
To study quantum gravity in asymptotically flat spacetimes, one would like to understand the algebra of observables at null infinity. Here we show that the Bondi mass cannot be obs…
