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…
Data-driven criteria for quantum correlations
Mateusz Krawczyk, JarosÅaw PawÅowski, Maciej M. MaÅka +1
We build a machine learning model to detect correlations in a three-qubit system using a neural network trained in an unsupervised manner on randomly generated states. The network…
