No-broadcasting characterizes operational contextuality
Pauli Jokinen, Mirjam Weilenmann, Martin Plávala +3
Operational contextuality forms a rapidly developing subfield of quantum information theory. However, the characterization of the quantum mechanical entities that fuel the phenomen…
Joint measurability in Lindbladian open quantum systems
Jukka Kiukas, Pekka Lahti, Juha-Pekka Pellonpää
We study joint measurability of quantum observables in open systems governed by a master equation of Lindblad form. We briefly review the historical perspective of open systems and…
Naimark dilations of qubit POVMs and joint measurements
Juha-Pekka Pellonpää, Sébastien Designolle, Roope Uola
Measurement incompatibility is one of the cornerstones of quantum theory. This phenomenon appears in many forms, of which the concept of non-joint measurability has received consid…
An attempt to understand relational quantum mechanics
Pekka Lahti, Juha-Pekka Pellonpää
We search for a possible mathematical formulation of some of the key ideas of the relational interpretation of quantum mechanics and study their consequences. We also briefly overv…
Amount of quantum coherence needed for measurement incompatibility
Jukka Kiukas, Daniel McNulty, Juha-Pekka Pellonpää
A pair of quantum observables diagonal in the same "incoherent" basis can be measured jointly, so some coherence is obviously required for measurement incompatibility. Here we firs…
An operational characterization of infinite-dimensional quantum resources
Erkka Haapasalo, Tristan Kraft, Juha-Pekka Pellonpää +1
Recently, various non-classical properties of quantum states and channels have been characterized through an advantage they provide in specific quantum information tasks over their…
