Multi-time advantage for certifying quantum coherence
Karol Sajnok, Fabio Costa
Non-classical dynamics in open quantum systems can be hidden in temporal correlations that are invisible to standard state- and channel-based tests. We define coherence for multi-t…

Resource theory of coherence in continuous position basis from measurement-induced dephasing
Karol Sajnok, Fabio Costa
We develop a resource-theoretic framework for quantum coherence directly in continuous basis, with emphasis on the position representation. Since position eigenstates are non-norma…
