Self-testing is a method to infer the underlying physics of a quantum experiment in a black
box scenario. As such it represents the strongest form of certification for quantum systems. In …

Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

Scalable generation of genuine multipartite entanglement with an increasing number of
qubits is important for both fundamental interest and practical use in quantum-information …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

We report the preparation and verification of a genuine 12-qubit entanglement in a
superconducting processor. The processor that we designed and fabricated has qubits lying …

Graph states,,—multipartite entangled states that can be represented by mathematical
graphs—are important resources for quantum computation, quantum error correction …

The recognition of the key role entanglement plays in the understanding of the radical
departure of quantum from classical physics came historically remarkably late. In the early …

We present a stack model for breaking down the complexity of entanglement-based
quantum networks. More specifically, we focus on the structures and architectures of …

Nonlocality was discovered by John Bell in 1964, in the context of the debates about
quantum theory, but is a phenomenon that can be studied in its own right. Its observation …
