Experimental Control of the Degree of Non-Classicality via Quantum Coherence
Andrea Smirne, Thomas Nitsche, Dario Egloff +6
The origin of non-classicality in physical systems and its connection to distinctly quantum features such as entanglement and coherence is a central question in quantum physics. Th…
Experimental quantification of coherence of a tunable quantum detector
Huichao Xu, Feixiang Xu, Thomas Theurer +5
Quantum coherence is a fundamental resource that quantum technologies exploit to achieve performance beyond that of classical devices. A necessary prerequisite to achieve this adva…
Accessible coherence in open quantum system dynamics
María García Díaz, Benjamin Desef, Matteo Rosati +5
Quantum coherence generated in a physical process can only be cast as a potentially useful resource if its effects can be detected at a later time. Recently, the notion of non-cohe…
When is a non-Markovian quantum process classical?
Simon Milz, Dario Egloff, Philip Taranto +4
More than a century after the inception of quantum theory, the question of which traits and phenomena are fundamentally quantum remains under debate. Here we give an answer to this…
Quantifying Operations with an Application to Coherence
Thomas Theurer, Dario Egloff, Lijian Zhang +1
To describe certain facets of non-classicality, it is necessary to quantify properties of operations instead of states. This is the case if one wants to quantify how well an operat…
Of Local Operations and Physical Wires
Dario Egloff, Juan Mauricio Matera, Thomas Theurer +1
In this work (multipartite) entanglement, discord and coherence are unified as different aspects of a single underlying resource theory defined through simple and operationally mea…
