چکیده

Here we present experimental realizations of two new entanglement detection methods: a three-measurement Bell inequality inequivalent to the Clauser-Horne-Shimony-Holt inequality and a nonlinear Bell-type inequality based on the negativity measure. In addition, we provide an experimental and theoretical comparison between these new methods and several techniques already in use: the traditional Clauser-Horne-Shimony-Holt inequality, the entanglement witness, and complete state tomography.

Detecting Quantum Entanglement: Positive Maps and Entanglement Witnesses

The interest on quantum entanglement has dramatically increased during the last 2 decades due to the emerging field of quantum information theory. It turns out that quantum entanglement may be used as basic resources in quantum information processing and communication. The prominent examples are quantum cryptography, quantum teleportation, quantum error correction codes, and quantum computation...

Max - Planck - Institut für Mathematik in den Naturwissenschaften Leipzig Inequalities Detecting Quantum Entanglement

We present a set of inequalities for detecting quantum entanglement of 2 ⊗ d quantum states. For 2 ⊗ 2 and 2 ⊗ 3 systems, the inequalities give rise to sufficient and necessary separability conditions for both pure and mixed states. For the case of d > 3, these inequalities are necessary conditions for separability, which detect all entangled states that are not positive under partial transposi...

Detecting quantum entanglement

We review the criteria for separability and quantum entanglement, both in a bipartite as well as a multipartite setting. We discuss Bell inequalities, entanglement witnesses, entropic inequalities, bound entanglement and several features of multipartite entanglement. We indicate how these criteria bear on the experimental detection of quantum entanglement.

Detecting entanglement using a double-quantum-dot turnstile.

We propose a scheme based on using the singlet ground state of an electron spin pair in a double-quantum-dot nanostructure as a suitable setup for detecting entanglement between electron spins via the measurement of an optimal entanglement witness. Using time-dependent gate voltages and magnetic fields the entangled spins are separated and coherently rotated in the quantum dots and subsequently...

Efficient Device-Independent Entanglement Detection for Multipartite Systems

Entanglement is one of the most studied properties of quantum mechanics for its application in quantum information protocols. Nevertheless, detecting the presence of entanglement in large multipartite sates continues to be a great challenge both from the theoretical and the experimental point of view. Most of the known methods either have computational costs that scale inefficiently with the nu...
