Entangling Topological Invariants
Kazuki Ikeda, Yaron Oz
An isolated occupied multiplet may admit local tensor-product descriptions without a globally consistent subsystem structure. We characterize the obstruction by comparing the trans…
Loop-dependent entangling holonomies in localized topological quartets
Kazuki Ikeda, Yaron Oz
A spectrally isolated quartet can admit a local two-qubit description at each point in parameter space and still acquire a loop holonomy outside the local subgroup $\mathrm{U}(2)\o…
Hofstadter's Butterfly in AdS Black Holes
Kazuki Ikeda, Yaron Oz
We derive the reduced Dirac Hamiltonian on the non-rotating BTZ background and use its redshift structure to construct a gauge-covariant single-band lattice model on the constant-t…
Quantum Information Dynamics of QED in Expanding de Sitter Universe
Kazuki Ikeda, Yaron Oz
We study QED in de Sitter space as a minimal interacting gauge theory in which cosmological expansion directly competes with quantum dynamics. In cosmic time, the hopping redsh…
Geometry Induced Chiral Transport and Entanglement in Background
Kazuki Ikeda, Yaron Oz
We study the real-time chiral dynamics of Dirac fermions in AdS and AdS black hole backgrounds. The spacetime curvature generates a spin connection term, acting as an effec…
Quantum Simulation of Fermions in Black Hole: Chirality, Entanglement, and Spectral Crossovers
Kazuki Ikeda, Yaron Oz
We consider free Dirac fermions on a discretized black hole background, and analyze how curved space redshift, horizons, and the spin connection induced chiral gravitationa…
Quantum Key Distribution by Quantum Energy Teleportation
Shlomi Dolev, Kazuki Ikeda, Yaron Oz
Quantum energy teleportation (QET) is a process that leverages quantum entanglement and local operations to transfer energy between two spatially separated locations without physic…
