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 negative-partial-transpose (NPT) states that are undistillable from one copy become distillable from finitely many copies remains a basic open problem in entanglement theor…
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…
Bell nonlocality from compatibility of entanglement-breaking channels
Gelo Noel M. Tabia, Chung-Yun Hsieh, Min-Hsiu Hsieh
Locally classical behavior is often interpreted as evidence that a global classical description should exist. In particular, when individual processes admit classical (measure-and-…
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…
Almost device-independent calibration beyond Born's rule: Bell tests for cross-talk detection
Gelo Noel M. Tabia, Alex Yueh-Ting Shih, Jin-Yuan Zheng +1
In quantum information, device-independent protocols offer a new approach to information processing tasks, making minimal assumptions about the devices used. Typically, since these…
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…
