Entropy Bounds via Hypothesis Testing and Its Applications to Two-Way Key Distillation in Quantum Cryptography
Rutvij Bhavsar, Junguk Moon, Joonwoo Bae
Quantum key distribution (QKD) achieves information-theoretic security, without relying on computational assumptions, by distributing quantum states. To establish secret bits, two…
Random Exclusion Codes: Quantum Advantages of Single-Shot Communication
Joonwoo Bae, Kieran Flatt, Teiko Heinosaari +4
Useful applications of quantum information technologies can be found by identifying tasks in which quantum resources outperform their classical counterparts. In this work, we intro…
Composable framework for device-independent state certification
Rutvij Bhavsar, Lewis Wooltorton, Joonwoo Bae
Certifying a quantum state in a device-independent (DI) manner, in which no trust is placed on the internal workings of any physical components, is a fundamental task bearing vario…
Sequential Quantum Maximum Confidence Discrimination
Hanwool Lee, Kieran Flatt, Joonwoo Bae
Sequential quantum information processing may lie in the peaceful coexistence of no-go theorems on quantum operations, such as the no-cloning theorem, the monogamy of correlations,…
