Identifier: http://hdl.handle.net/1959.14/39973
Description: We determine the entanglement capability of a self-inverse Hamiltonian evolution, which reduces to the known result for the Ising Hamiltonian, and identify optimal input states for yielding the maxima ... More

Identifier: http://hdl.handle.net/1959.14/39624
Description: We introduce the entanglement gauge describing the combined effects of local operations and nonlocal unitary transformations on bipartite quantum systems. The entanglement gauge exploits the invarianc ... More

Identifier: http://hdl.handle.net/1959.14/39614
Description: We introduce the quantum quincunx, which physically demonstrates the quantum walk and is analogous to Galton’s quincunx for demonstrating the random walk by employing gravity to draw pellets through p ... More

Identifier: http://hdl.handle.net/1959.14/39731
Description: Two-qubit operations may be characterized by their capacities for communication, both with and without free entanglement, and their capacity for creating entanglement. We establish a set of inequaliti ... More

Identifier: http://hdl.handle.net/1959.14/39983
Description: We study relations between bosonic quadrature squeezing and atomic spin squeezing, and find that the latter reduces to the former in the limit of a large number of atoms for even and odd states. We de ... More

Identifier: http://hdl.handle.net/1959.14/39634
Description: We show that spin squeezing implies pairwise entanglement for arbitrary symmetric multiqubit states. If the squeezing parameter is less than or equal to 1, we demonstrate a quantitative relation betwe ... More
