Combinatorial aspects of holographic quantum secret sharing

Ning Bao, Keiichiro Furuya, Jacob March

We introduce combinatorial holographic quantum secret sharing (CHQSS) for a bulk subregion in AdS/CFT to study how logical information of the bulk subregion is encoded in t…

Phase transitions and uberholography of holographic pure-state geometries

Ning Bao, Keiichiro Furuya, Jacob March

We study the error-correcting properties of pure-state holographic geometries, in which mixed boundary subregions are replaced, via the surface/state correspondence, by the Ryu--Ta…

Entanglement cohomology for GHZ and W states

Christian Ferko, Keiichiro Furuya

Entanglement cohomology assigns a graded cohomology ring to a multipartite pure state, providing homological invariants that are stable under local unitaries and characterize inequ…

Tripartite Correlation Signal from Multipartite Entanglement of Purification

Ning Bao, Keiichiro Furuya, Joydeep Naskar

We propose a signal for genuine tripartite entanglement in finite-dimensional quantum systems and for holographic systems. We prove that is non-…

On the completeness of contraction map proof method for holographic entropy inequalities

Ning Bao, Keiichiro Furuya, Joydeep Naskar

The contraction map proof method is the commonly used method to prove holographic entropy inequalities. Existence of a contraction map corresponding to a holographic entropy inequa…

Symmetry Properties of Quantum Dynamical Entropy

Eric D. Schultz, Keiichiro Furuya, Laimei Nie

As quantum analogs of the classical Kolmogorov-Sinai entropy, quantum dynamical entropies have emerged as important tools to characterize complex quantum dynamics. In particular, A…
