Report

Bounding the entanglement of N qubits with only four measurements

Autor: Rafsanjani, S. M. Hashemi, Broadbent, C. J., Eberly, J. H.

Publikováno v: Phys. Rev. A 88, 062331 (2013)

We introduce a new measure for the genuinely N-partite (all-party) entanglement of N-qubit states using the trace distance metric, and find an algebraic formula for the GHZ-diagonal states. We then use this formula to show how the all-party entanglem

Bell violation for unknown continuous-variable states

Autor: Qian, X. -F., Broadbent, C. J., Eberly, J. H.

Publikováno v: New Journal of Physics 16 (2014) 013033

We describe a new Bell test for two-particle entangled systems that engages an unbounded continuous variable. The continuous variable state is allowed to be arbitrary and inaccessible to direct measurements. A systematic method is introduced to perfo

Genuinely Multipartite Concurrence of N-qubit X-matrices

Autor: Rafsanjani, S. M. Hashemi, Huber, M., Broadbent, C. J., Eberly, J. H.

Publikováno v: Physical Review A 86, 062303 (2012)

We find an algebraic formula for the N-partite concurrence of N qubits in an X-matrix. X- matricies are density matrices whose only non-zero elements are diagonal or anti-diagonal when written in an orthonormal basis. We use our formula to study the

Report

Experimental Violation of Two-Party Leggett-Garg Inequalities with Semi-weak Measurements

Autor: Dressel, J., Broadbent, C. J., Howell, J. C., Jordan, A. N.

Publikováno v: Phys.Rev.Lett.106:040402,2011

We generalize the derivation of Leggett-Garg inequalities to systematically treat a larger class of experimental situations by allowing multi-particle correlations, invasive detection, and ambiguous detector results. Furthermore, we show how many suc
