Entanglement with a mode observable via a tunable interaction with a qubit
Małgorzata Strzałka, 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 Płodzień, 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…
Qubit-environment entanglement in time-dependent pure dephasing
Małgorzata Strzałka, Radim Filip, Katarzyna Roszak
We show that the methods for quantification of system-environment entanglement that were recently developed for interactions that lead to pure decoherence of the system can be stra…
Data-driven criteria for quantum correlations
Mateusz Krawczyk, Jarosław Pawłowski, Maciej M. Maśka +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…
A signature of quantumness in pure decoherence control
Bartosz Rzepkowski, Katarzyna Roszak
We study a decoherence reduction scheme that involves an intermediate measurement on the qubit in an equal superposition basis, in the general framework of all qubit-environment in…
