Two-Rebit Entanglement: Theory and Experiment

2021 · Quantum Information and Measurement VI 2021

We characterize entanglement over real and complex, composite quantum systems. Methods are formulated and applied to simultaneously certify inseparability and separability for two rebits and two qubits, respectively.

Certifying the Topology of Quantum Networks: Theory and Experiment

2023 · arXiv (Cornell University)

Distributed quantum information in networks is paramount for global secure quantum communication. Moreover, it finds applications as a resource for relevant tasks, such as clock synchronization, magnetic field sensing, and blind quantum computation. For quantum …
