de Sitter space, extremal surfaces, and time entanglement

K Narayan - Physical Review D, 2023‏ - APS
We refine previous investigations on de Sitter space and extremal surfaces anchored at the
future boundary I+. Since such surfaces do not return, they require extra data or boundary …

Entangled universes in dS wedge holography

SE Aguilar-Gutierrez, AK Patra, JF Pedraza - Journal of High Energy …, 2023‏ - Springer
A bstract We develop a new setting in the framework of braneworld holography to describe a

From time-reversal symmetry to quantum Bayes' rules

AJ Parzygnat, J Fullwood - PRX Quantum, 2023‏ - APS
Bayes' rule, P (B| A) P (A)= P (A| B) P (B), is one of the simplest yet most profound,
ubiquitous, and far-reaching results of classical probability theory, with applications in any …
