Flatness-Preserving Operations
Otto Veltheim, Esko Keski-Vakkuri
A quantum state is called flat if it is proportional to a projector. There has been recent interest in studying antiflatness, the property of diverging from flat states, and establ…
Induced Resource Theories and Harvesting via Quantum Probes
Ron Nyström, Simone Cepollaro, Nicola Pranzini +3
We consider scenarios in which a quantum system with a well-defined resource theory is used as a probe to interact with an environment, such as a quantum field, for which a resourc…
Quantum Darwinism and the quality of Petz recovery
Juha Torvinen, Esko Keski-Vakkuri, Nicola Pranzini
According to Quantum Darwinism, system-environment interactions both einselect particular system properties and encode them redundantly in many independent subsets of the environme…
Bipartite entanglement harvesting with multiple detectors
Santeri Salomaa, Esko Keski-Vakkuri, Sergi Nadal-Gisbert
We study bipartite entanglement harvesting from the quantum vacuum of a massless scalar field between two subsystems, each composed of a finite number of Unruh-DeWitt detectors. Us…
Detector-based measurement-induced state updates in AdS/CFT
Vijay Balasubramanian, Esko Keski-Vakkuri, Nicola Pranzini
Conventional understandings of quantum theory hold that measurements change the state of an observed system following the Lüders update rule. Textbooks describe the application of…
Continuous majorization in quantum phase space for Wigner-positive states and proposals for Wigner-negative states
Jan de Boer, Giuseppe Di Giulio, Esko Keski-Vakkuri +1
In quantum resource theory, one is often interested in identifying which states serve as the best resources for particular quantum tasks. If a relative comparison between quantum s…
