Subregion observer rules from generalized entanglement wedges
Lana Bozanic, Kenneth Higginbotham, Chris Waddell
We consider rules for modifying holographic tensor networks proposed in two independent contexts: by the Colorado (CO) group in 2503.09681 to incorporate observers in holographic m…
Comparing classical and quantum conditional disclosure of secrets
Uma Girish, Alex May, Leo Orshansky +1
The conditional disclosure of secrets (CDS) setting is among the most basic primitives studied in information-theoretic cryptography. Motivated by a connection to non-local quantum…
Conditional disclosure of secrets with quantum resources
Vahid R. Asadi, Kohdai Kuroiwa, Debbie Leung +3
The conditional disclosure of secrets (CDS) primitive is among the simplest cryptographic settings in which to study the relationship between communication, randomness, and securit…
On sufficient conditions for holographic scattering
Caroline Lima, Sabrina Pasterski, Chris Waddell
Holography implies scattering in the bulk can be mediated by entanglement on the boundary. The connected wedge theorem (CWT) of May, Penington, and Sorce is a concrete example wher…
Cryptographic tests of the python's lunch conjecture
Alex May, Sabrina Pasterski, Chris Waddell +1
In the AdS/CFT correspondence, a subregion of the CFT allows for the recovery of a corresponding subregion of the bulk known as its entanglement wedge. In some cases, an entangleme…
