Quantum logic between atoms inside a high Q optical cavity
We propose a protocol for conditional quantum logic between two 4-state atoms
inside a high Q optical cavity. The process detailed in this paper utilizes a
direct 4-photon 2-atom resonant process and has the added advantage of commonly
addressing the two atoms when they are inside the high Q optical cavity.Comment: 8 pages, 3 figs. submitte
Generation of two-mode nonclassical states and a quantum phase gate operation in trapped ion cavity QED
We propose a scheme to generate nonclassical states of a quantum system,
which is composed of the one-dimensional trapped ion motion and a single cavity
field mode. We show that two-mode SU(2) Schr\"odinger-cat states, entangled
coherent states, two-mode squeezed vacuum states and their superposition can be
generated. If the vibration mode and the cavity mode are used to represent
separately a qubit, a quantum phase gate can be implemented.Comment: to appear in PR
