No-go theorems on simulating uncertainty principle's signatures
Chung-Yun Hsieh, Minjeong Song, Shin-Liang Chen
Uncertainty principle, one of the most iconic features of quantum mechanics, was originally viewed as a fundamental limitation. Since the inception of quantum information science,…
Universal method for optimized robustness in self-testing of quantum resources
Shin-Liang Chen, Nikolai Miklin
Self-testing is a phenomenon where the use of specific quantum states or measurements can be inferred solely from the correlations they generate. We introduce a universal method fo…
Investigating an approach of robustly self-testing two-qubit entangled states
Chan-Ching Lien, Shin-Liang Chen
In a recent paper [Quantum 5, 552 (2021)], the authors proposed a framework for robustly self-testing steerable quantum assemblages. In this work, we apply their method to the scen…
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…
Thermodynamic Approach to Quantifying Incompatible Instruments
Chung-Yun Hsieh, Shin-Liang Chen
We consider a thermodynamic framework to quantify instrument incompatibility via a resource theory subject to thermodynamic constraints. We use the minimal thermalisation time need…
