Unspeakable Coherence Concentration
Benjamin Stratton, Chung-Yun Hsieh, Paul Skrzypczyk
Unspeakable coherence is a key feature separating quantum and classical physics. Modelled as asymmetry with respect to a continuous transformation generated by a physically relevan…
Operational Interpretation of the Choi Rank Through k-State Exclusion
Benjamin Stratton, Chung-Yun Hsieh, Paul Skrzypczyk
The Choi-state is an indispensable tool in the study and analysis of quantum channels. Considering a channel in terms of its associated Choi-state can greatly simplify problems. It…
Informational non-equilibrium concentration
Chung-Yun Hsieh, Benjamin Stratton, Hao-Cheng Weng +1
Informational contributions to thermodynamics can be studied in isolation by considering systems with fully-degenerate Hamiltonians. In this regime, being in non-equilibrium -- ter…
Dynamical Landauer principle: Thermodynamic criteria of transmitting classical information
Chung-Yun Hsieh
Transmitting energy and information are two essential aspects of nature. Recent findings suggest they are closely related, while a quantitative equivalence between them is still un…
Dynamical resource theory of incompatibility preservability
Chung-Yun Hsieh, Benjamin Stratton, Chao-Hsien Wu +1
The uncertainty principle is one of quantum theory's most foundational features. It underpins a quantum phenomenon called measurement incompatibility -- two physical observables of…
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…
