Rydberg blockade, Förster resonances, and quantum state measurements with different atomic species
نویسنده
چکیده
We calculate interspecies Rydberg-Rydberg interaction strengths for the heavy alkali metals Rb and Cs. The presence of strong Förster resonances makes interspecies coupling a promising approach for long-range entanglement generation. We also provide an overview of the strongest Förster resonances for Rb-Rb and Cs-Cs using different principal quantum numbers for the two atoms. We show how interspecies coupling can be used for high fidelity quantum nondemolition state measurements with low cross-talk in qubit arrays.

Quantum magnetism and topological ordering via enhanced Rydberg-dressing near Förster-resonances
We devise a cold-atom approach to realizing a broad range of bi-linear quantum magnets. Our scheme is based on off-resonant single-photon excitation of Rydberg P -states (Rydberg-dressing), whose strong interactions are shown to yield controllable XYZ-interactions between effective spins, represented by different atomic ground states. The distinctive features of Förster-resonant Rydberg atom in...

متن کاملProspect nuclids for first isotope shift experiments by means of dielectronic recombination
The measurement of isotopic shifts utilizing dielectronic recombination (DR) of very heavy few electron ions (nuclear charge Z > 50) is a very promising new approach for the investigation of nuclear properties. In particular if an s-core-electron is excited during the initial dielectronic capture (DC) process the large change in the overlap of atomic and nuclear wavefunctions leads to strong nu...
متن کاملFast Rydberg gates without dipole blockade via quantum control
We propose a scheme for controlling interactions between Rydberg-excited neutral atoms in order to perform a fast high-fidelity quantum gate. Unlike dipole-blockade mechanisms already found in the literature, we drive resonantly the atoms with a state-dependent excitation to Rydberg levels, and we exploit the resulting dipoledipole interaction to induce a controlled atomic motion in the trap, i...
