Identifier: http://hdl.handle.net/1959.14/29387
Description: We introduce quantum hybrid gates that act on qudits of different dimensions. In particular, we develop two representative two-qudit hybrid gates (SUM and SWAP) and many-qudit hybrid Toffoli and Fredk ... 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

Identifier: http://hdl.handle.net/1959.14/28999
Description: We propose a spin squeezing criterion for arbitrary multi-qubit states that is invariant under local unitary operations. We find that, for arbitrary pure two-qubit states, spin squeezing is equivalent ... More
