Abstract: We consider the unambiguous discrimination of multipartite quantum states and provide an upper bound for the maximum success probability of optimal local discrimination. We also provide a necessary and sufficient condition to realize the upper bound. We further establish a necessary and sufficient condition for this upper bound to be saturated. Finally, we illustrate our results using examples in multidimensional multipartite quantum systems.

Multipartite entanglement theory with entanglement-nonincreasing operations [91.3755431537592]
We extend the resource theory of entanglement for multipartite systems beyond the standard framework of local operations and classical communication. We demonstrate that in this adjusted framework, the transformation rates between multipartite states are fundamentally dictated by the bipartite entanglement entropies of the respective quantum states.

Entanglement witness and multipartite quantum state discrimination [0.0]
We consider multipartite quantum state discrimination and show that the minimum-error discrimination by separable measurements is closely related to the concept of entanglement witness. Based on the properties of entanglement witness, we establish some necessary and/or sufficient conditions on minimum-error discrimination by separable measurements.

Efficient criteria of quantumness for a large system of qubits [58.720142291102135]

Experimental multi-state quantum discrimination through a Quantum network [63.1241529629348]
We have experimentally implemented two discrimination schemes in a minimum-error scenario based on a receiver featured by a network structure and a dynamical processing of information. The first protocol achieves binary optimal discrimination, while the second one provides a novel approach to multi-state quantum discrimination, relying on the dynamical features of the network-like receiver.

The best approximation of an objective state with a given set of quantum states [1.0249024223548817]
Approximating a quantum state by the convex mixing of some given states has strong experimental significance. We find a closed form of the minimal distance in the sense of l norm between a given d-dimensional objective quantum state and the state convexly mixed by those restricted in any given (mixed-) state set.

Characterizing multipartite entanglement by violation of CHSH inequalities [15.437374103470939]
Entanglement of high-dimensional and multipartite quantum systems offer promising perspectives in quantum information processing. We consider the overlaps between the maximal quantum mean values and the classical bound of the CHSH inequalities for pairwise-qubit states in two-dimensional subspaces. We show that the concurrence of a pure state in any high-dimensional multipartite system can be equivalently represented by these overlaps.

Fermionic state discrimination by local operations and classical communication [68.8204255655161]
Local operations and classical communication (LOCC) discrimination between two bipartite pure states of fermionic systems is studied. We show that, contrary to the case of quantum systems, for fermionic systems it is generally not possible to achieve the ideal state discrimination performances.
