We investigate the possibility of multiple uses of a single copy of a three-qubit state for
detecting genuine tripartite Einstein-Podolsky-Rosen (EPR) steering. A pure three-qubit …

Many-body quantum systems can be characterized using the notions of k-separability and
entanglement depth. A quantum state is k-separable if it can be expressed as a mixture of k …

We introduce a purely geometric formulation for two different measures addressed to
quantify the entanglement between different parts of a tripartite qubit system. Our approach …

We introduce a strategy to regulate the quantum entanglement in a dispersive-hybrid system
where a qubit is directly coupled to a cavity and a resonator. A dramatic transition takes …

Suppose we have an unknown multipartite quantum state, how can we experimentally find
out whether it is genuine multipartite entangled or not? Recall that even for a bipartite …

Genuine multipartite entanglement is crucial for quantum information and related
technologies, but quantifying it has been a long-standing challenge. Most proposed …

We have reexamined the moments of positive maps and the criterion based on these
moments to detect entanglement. For two qubits, we observed that reduction map is …

We present the generalized state-dependent entropic uncertainty relations in a multiple
measurements setting and the optimal lower bound is obtained by considering different …

Genuine multipartite entanglement is crucial for quantum information and related
technologies but quantifying it has been a long-standing challenge. Most proposed …

Two cavity‐magnon subsystems coupled via the two single‐mode cavities mediated by a
non‐degenerate parametric down conversion and each cavity carrying a magnon confined …
