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…
One-Query Quantum Algorithms for the Index- Hidden Subgroup Problem
Amit Te'eni, Yaron Oz, Eliahu Cohen
The quantum Fourier transform (QFT) is central to many quantum algorithms, yet its necessity is not always well understood. We re-examine its role in canonical query problems. The…
Generalized Fusion of Qudit Graph States
N. Rimock, Y. Oz
We formalize a generalized type-II fusion operation for qudit cluster states within linear optics. Two designated qudits, one from each input cluster, interfere with optional ancil…
Quantum Key Distribution via Charge Teleportation
Amir Yona, Yaron Oz
We demonstrate that charge teleportation serves as a superior observable for Quantum Energy Teleportation (QET)-based cryptographic primitives. While following the LOCC protocol st…
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…
