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…

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…
