Quantum steering in networks: Measurement-device-independent detection, continuous variables, and practical Gaussian schemes
Shao-Hua Hu, Chung-Yun Hsieh, Huan-Yu Ku +2
We consider quantum steering certification in multipartite networks, with a focus on minimal trust scenarios: all-except-one parties are untrusted and treated device-independently.…
Resource theory of interactive quantum instruments
Chung-Yun Hsieh, Armin Tavakoli, Huan-Yu Ku +1
Quantum instruments describe both the classical outcome and the updated quantum state in a measurement process. To do this in a non-trivial way, instruments must have the capabilit…
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,…
Complete characterisation of state conversions by work extraction
Chung-Yun Hsieh, Manuel Gessner
We introduce a thermodynamic work extraction task that describes the energy storage enhancement of quantum systems. This task induces majorisation-like conditions that provide a ne…
General quantum resources providing advantages in work-extraction tasks
Chung-Yun Hsieh, Manuel Gessner
In developing quantum science and technologies, it is essential to demonstrate so-called quantum advantages, which are performances that can be achieved only with the assistance of…
