Experimental detection of quantum entanglement

Abstract

In this review, we introduce some methods for detecting or measuring entanglement. Several nonlinear entanglement witnesses are presented. We derive a series of Bell inequalities whose maximally violations for any multipartite qubit states can be calculated by using our formulas. Both the nonlinear entanglement witnesses and the Bell inequalities can be operated experimentally. Thus they supply an effective way for detecting entanglement. We also introduce some experimental methods to measure the entanglement of formation, and the lower bound of the convex-roof extension of negativity.

Experimental Methods for Detecting Entanglement

Joseph B. Altepeter, Evan R. Jeffrey, Paul G. Kwiat +3 more

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.

Bell inequalities for multipartite qubit quantum systems and their maximal violation

Ming Li, Shao-Ming Fei

We present a set of Bell inequalities for multiqubit quantum systems. These Bell inequalities are shown to be able to detect multiqubit entanglement better than previous Bell inequalities such as Werner-Wolf-Zukowski-Brukner ones. Computable formulas are presented for calculating the maximal violations of these Bell inequalities for any multiqubit states.

Bell inequality for multipartite qubit quantum system and the maximal violation

Ming Li, Shao-Ming Fei

Abstract We present a set of Bell inequalities for multi-qubit quantum systems. These Bell inequalities are shown to be able to detect multi-qubit entanglement better than previous Bell inequalities such as WWZB ones. Computable formulas are presented for calculating the maximal violations of these Bell inequalities for any multi-qubit states.

Entanglement Detection with Trace Polynomials

Albert Rico, Felix Huber

We provide a systematic method for nonlinear entanglement detection based on trace polynomial inequalities. In particular, this allows us to employ multipartite witnesses for the detection of bipartite states, and vice versa. We identify pairs of entangled states and witnesses for which linear detection fails, but for which nonlinear detection succeeds. With the trace polynomial formulation a great variety of witnesses arise from immanant inequalities, which can be implemented in the laboratory through the randomized measurements toolbox.

Detecting Genuine Multipartite Entanglement with Two Local Measurements

Géza Tóth, Otfried Gühne

We present entanglement witness operators for detecting genuine multipartite entanglement. These witnesses are robust against noise and require only two local measurement settings when used in an experiment, independent of the number of qubits. This allows detection of entanglement for an increasing number of parties without a corresponding increase in effort. The witnesses presented detect states close to Greenberger-Horne-Zeilinger, cluster, and graph states. Connections to Bell inequalities are also discussed.

Evaluation of entanglement measures by a single observable

Chengjie Zhang, Sixia Yu, Qing Chen +2 more

We present observable lower bounds for several bipartite entanglement measures including entanglement of formation, geometric measure of entanglement, concurrence, convex-roof extended negativity, and $G$ concurrence. The lower bounds facilitate estimates of these entanglement measures for arbitrary finite-dimensional bipartite states. Moreover, these lower bounds can be calculated analytically from the expectation value of a single observable. Based on our results, we use several real experimental measurement data to get lower bounds of entanglement measures for these experimentally realized states. In addition, we also study the relations between entanglement measures.
