Quantum measurement incompatibility in subspaces
Roope Uola, Tristan Kraft, Sébastien Designolle +5
We consider the question of characterising the incompatibility of sets of high-dimensional quantum measurements. We introduce the concept of measurement incompatibility in subspace…
Monogamy relations of quantum coherence between multiple subspaces
Tristan Kraft, Marco Piani
Quantum coherence plays an important role in quantum information protocols that provide an advantage over classical information processing. The amount of coherence that can exist b…
All quantum resources provide an advantage in exclusion tasks
Roope Uola, Tom Bullock, Tristan Kraft +2
A key ingredient in quantum resource theories is a notion of measure. Such as a measure should have a number of fundamental properties, and desirably also a clear operational meani…
Quantification of quantum dynamics with input-output games
Roope Uola, Tristan Kraft, Alastair A. Abbott
Recent developments surrounding resource theories have shown that any quantum state or measurement resource, with respect to a convex (and compact) set of resourceless objects, pro…
Quantifying quantum resources with conic programming
Roope Uola, Tristan Kraft, Jiangwei Shang +2
Resource theories can be used to formalize the quantification and manipulation of resources in quantum information processing such as entanglement, asymmetry and coherence of quant…
