Bounding Two-Way Average Communication Cost of Simulating Quantum Correlations
Kai-Siang Chen, Gelo Noel M. Tabia, Bo-An Tsai +2
Bell nonlocal correlations cannot be reproduced by local hidden-variable models without communication, making classical communication cost a natural quantitative measure of nonloca…
Two-copy distillability of one-copy-undistillable negative-partial-transpose states in every dimension
Gelo Noel M. Tabia, Kai-Siang Chen, Min-Hsiu Hsieh
Whether entanglement with a negative partial transpose (NPT) can be undistillable is a longstanding open problem. In the canonical family of DiVincenzo \textit{et al.}, the one-cop…
Trading symmetry for Hilbert-space dimension in Bell-inequality violation
Hsin-Yu Hsu, Gelo Noel M. Tabia, Kai-Siang Chen +4
In quantum information, asymmetry, i.e., the lack of symmetry, is a resource allowing one to accomplish certain tasks that are otherwise impossible. Similarly, in a Bell test using…
Large Parts are Generically Entangled Across All Cuts
Mu-En Liu, Kai-Siang Chen, Chung-Yun Hsieh +2
Generic high-dimensional bipartite pure states are overwhelmingly likely to be highly entangled. Remarkably, this ubiquitous phenomenon can already arise in finite-dimensional syst…
Nonlocality of Quantum States can be Transitive
Kai-Siang Chen, Gelo Noel M. Tabia, Chung-Yun Hsieh +2
As a striking manifestation of quantum entanglement, nonlocality has long played a pivotal role in shaping our understanding of the quantum world. When considering a Bell test invo…
Experimental single-copy distillation of quantumness from higher-dimensional entanglement
Xiao-Xu Fang, Gelo Noel M. Tabia, Kai-Siang Chen +2
Entanglement is at the heart of quantum theory and is responsible for various quantum-enabling technologies. In practice, during its preparation, storage, and distribution to the i…
Protocols and Trade-Offs of Quantum State Purification
Hongshun Yao, Yu-Ao Chen, Erdong Huang +3
Quantum state purification is crucial in quantum communication and computation, aiming to recover a purified state from multiple copies of an unknown noisy state. This work introdu…
Incorporating Zero-Probability Constraints to Device-Independent Randomness Expansion
Chun-Yu Chen, Kai-Siang Chen, Kai-Min Chung +3
One of the distinguishing features of quantum theory is that its measurement outcomes are usually unpredictable or, equivalently, random. Moreover, this randomness is certifiable w…
Device-independent certification of desirable properties with a confidence interval
Wan-Guan Chang, Kai-Chun Chen, Kai-Siang Chen +2
In the development of quantum technologies, a reliable means for characterizing quantum devices is crucial. However, the conventional approach based on, e.g., quantum state tomogra…
Hardy-type paradoxes for an arbitrary symmetric bipartite Bell scenario
Kai-Siang Chen, Shiladitya Mal, Gelo Noel M. Tabia +1
As with a Bell inequality, Hardy's paradox manifests a contradiction between the prediction given by quantum theory and local-hidden variable theories. In this work, we give two ge…
Quantum correlations on the no-signaling boundary: self-testing and more
Kai-Siang Chen, Gelo Noel M. Tabia, Chellasamy Jebarathinam +3
In device-independent quantum information, correlations between local measurement outcomes observed by spatially separated parties in a Bell test play a fundamental role. Even thou…
Entanglement transitivity problems
Gelo Noel M. Tabia, Kai-Siang Chen, Chung-Yun Hsieh +2
One of the goals of science is to understand the relation between a whole and its parts, as exemplified by the problem of certifying the entanglement of a system from the knowledge…
