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…
Sharing quantum indistinguishability with multiple parties
Lemieux Wang, Hanwool Lee, Joonwoo Bae +1
Quantum indistinguishability of non-orthogonal quantum states is a valuable resource in quantum information applications such as cryptography and randomness generation. In this art…
Contextual advantages across two-state discrimination strategies
Kieran Flatt, Joonwoo Bae
Quantum state discrimination, alongside its other applications, has recently found use as a tool for witnessing generalised contextuality. In this article, we derive noncontextuali…
Sequential Semi-Device-Independent Quantum Randomness Certification
Carles Roch I Carceller, Hanwool Lee, Jonatan Bohr Brask +2
Quantum measurements under realistic conditions reveal only partial information about a system. Yet, by performing sequential measurements on the same system, additional informatio…
Enhancing Sum Capacity via Quantum and No-Signaling Cooperation Between Transmitters
Seung-Hyun Nam, Hyun-Young Park, Jiyoung Yun +3
We consider communication over discrete memoryless interference channels or multiple access channels without feedback, where transmitters exploit classical, quantum, or no-signalin…
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…
Quantum Advantage in Locally Differentially Private Hypothesis Testing
Seung-Hyun Nam, Hyun-Young Park, Si-Hyeon Lee +1
We consider a private hypothesis testing scenario, including both symmetric and asymmetric testing, based on classical data samples. The utility is measured by the error exponents,…
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,…
