Experimentally accessible non-separability criteria for multipartite entanglement structure detection
Guillermo García-Pérez, Oskari Kerppo, Matteo A. C. Rossi +1
The description of the complex separability structure of quantum states in terms of partially ordered sets has been recently put forward. In this work, we address the question of h…
Reheating in the kination epoch via multi-channel decay of gravitationally created massive scalars
Juho Lankinen, Oskari Kerppo, Iiro Vilja
We provide a detailed study of reheating in the kination regime in a scenario where the particle content is produced by gravitational production of massive scalars decaying into ma…
Communication tasks in operational theories
Teiko Heinosaari, Oskari Kerppo, Leevi Leppäjärvi
We investigate the question which communication tasks can be accomplished within a given operational theory. The concrete task is to find out which communication matrices have a pr…
Reheating via gravitational particle production in kination epoch
Juho Lankinen, Oskari Kerppo, Iiro Vilja
We provide a detailed study of reheating in the kination regime where particle content is created by gravitational production of massive scalars mutually interacting with a massles…
Communication of partial ignorance with qubits
Teiko Heinosaari, Oskari Kerppo
We introduce a class of communication tests where the task is to communicate partial ignorance by means of a physical system. We present a full characterization of the implementati…
Entanglement Protection via Periodic Environment Resetting in Continuous Time Quantum Dynamical Processes
Thomas Bullock, Francesco Cosco, Marwan Haddara +8
The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a coup…
