Baby universe as logical qubits: information recovery in random encoding
Takato Mori, Beni Yoshida
We revisit whether a semiclassical closed baby universe in AdS/CFT necessarily possess a trivial one-dimensional Hilbert space or may instead carry a large entropy. Recent results…

Entanglement sharing schemes
Zahra Khanian, Dongjin Lee, Debbie Leung +7
We ask how quantum correlations can be distributed among many subsystems. To address this, we define entanglement sharing schemes (ESS) where certain pairs of subsystems allow enta…

Tripartite Haar random state has no bipartite entanglement
Zhi Li, Takato Mori, Beni Yoshida
We show that no EPR-like bipartite entanglement can be distilled from a tripartite Haar random state by local unitaries or local operations when each subsystem $A…
