Hayden--Preskill recovery at finite temperature on a quantum processor: dynamics and initial state from the SYK model
Jeongho Bang, Moongul Byun, Kyoungho Cho +2
The paper extends the Hayden‑Preskill information recovery protocol by linking the scrambler to the initial state with a SWAP gate and studying recovery at finite temperature, show…
Probing the Hierarchy of Genuine Multipartite Entanglement with Generalized Latent Entropy
Byoungjoon Ahn, Jaydeep Kumar Basak, Keun-Young Kim +3
We introduce generalization of the recently proposed \textit{Latent Entropy} (L-entropy) \cite{Basak:2024uwc} as a refined measure of genuine multipartite entanglement (GME) in pur…
Quantum simulation of traversable-wormhole-inspired quantum teleportation in a chaotic binary sparse SYK model
Moongul Byun, Keun-Young Kim, Hyeonsoo Lee
We report the experimental observation of holographically motivated quantum teleportation on a quantum processor, driven by the highly entangled, chaotic dynamics of a many-body sy…
Aspects of holographic timelike entanglement entropy in black hole backgrounds
Mir Afrasiar, Jaydeep Kumar Basak, Keun-Young Kim
We study the holographic construction of timelike entanglement entropy (tEE) in black hole backgrounds in Lorentzian geometries. The holographic tEE is realized through extremal su…
