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…

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…

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…

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…
