Entanglement with a mode observable via a tunable interaction with a qubit
MaÅgorzata StrzaÅka, Radim Filip, Katarzyna Roszak
We study the possibility of detection of ``spin-boson'' entanglement by qubit only measurements. Such entanglement is impossible to detect by previously proposed schemes that invol…

Experimental protocol for qubit-environment entanglement detection
Gabriele Bizzarri, Linda Sansoni, Eleonora Stefanutti +4
Decoherence is a manifestation of the coupling of a system with its environment. The resulting loss of information can hamper the functioning of quantum devices, hence the need of…

Harnessing spin-qubit decoherence to probe strongly-interacting quantum systems
Marcin PÅodzieÅ, Sambunath Das, Maciej Lewenstein +2
Extracting information from quantum many-body systems remains a key challenge in quantum technologies due to experimental limitations. In this work, we employ a single spin qubit t…
