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 …

A new development in the dynamical behavior of elementary quantum systems is the
surprising discovery that correlation between two quantum units of information called qubits …

Standard quantum computation is based on sequences of unitary quantum logic gates that
process qubits. The one-way quantum computer proposed by Raussendorf and Briegel is …

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

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 …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

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 …

Light states composed of multiple entangled photons—such as cluster states—are essential
for develo** and scaling-up quantum computing networks. Photonic cluster states can be …

We develop an original approach for the quantitative characterisation of the entanglement
properties of, possibly mixed, bi-and multipartite quantum states of arbitrary finite dimension …
