Energy-constrained two-way capacities pure-loss bosonic Project Details
| Abstract |
This project studies the theory and simulation of two‑way quantum communication over pure‑loss bosonic channels when realistic energy limits are in place. It tackles the long‑standing problem of finding the exact quantum, entanglement‑distribution, private, and secret‑key capacities when the average number of transmitted photons is fixed without any extra conditions. The work uses a new technique called sector‑teleportation simulation. This method shows how to move the input‑energy restriction directly onto the shared entanglement that the protocol uses. By doing so, the energy limit stays intact throughout the converse arguments for adaptive protocols. A simulation model tests the reverse‑coherent‑information rate and shows that it is optimal for a wide range of
channel transmissivities and average photon numbers. The analysis also sets strong‑converse thresholds for both adaptive protocols and parallel protocols that impose a hard total‑photon‑number cutoff. The resulting models reveal that finite‑energy constraints change both the achievable transmission rates and the corresponding converse bounds in quantum optical communication systems. This research provides a solid foundation for further work on quantum key distribution and the design of secure optical networks.
