| On the attainability of the ultimate limits in quantum multiparameter estimation | QIP 2026 | ▸Lorcan Conlon, Aritra Das, Simon Yung, Jun Suzuki |
| Efficient entanglement swapping via lossy channels | QCRYPT 2024 | Wan Zo, Bohdan Bilash, Donghwa Lee, Yosep Kim, Hyang-Tag Lim, Kyunghwan Oh, Yong-Su Kim |
We investigate an entanglement swapping protocol using photon-number-encoded states to alleviate quantum channel losses without requiring quantum memories. The protocol achieves entanglement distribution probability scaling linearly with channel transmission. Unbalanced channel losses can degrade the entanglement, but this is compensated by optimally adjusting the initial states. |

| Fast real time secure quantum random number generator based on quantum vacuum fluctuations | QCRYPT 2013 | Thomas Symul, Jing Yan Haw, Ping Koy Lam |
We present a robust real time quantum random number generator based on broadband measurements of the quantum fluctuations of the vacuum field. Even though ANY optical measurements may contain potentially untrusted technical noise, we show that suitable algorithms can transform the digitised photo-current into a unique string of random numbers that are immune to environmental tempering and are absolutely indeterministic. Our device achieves a continuous generation bandwidth of 5.7 Gb/s, and is verified using statistical randomness tests. |
