We propose to create superposition states of over 100 Strontium atoms being in a ground state or metastable optical clock state, using the Kerr-type interaction due to Rydberg state dressing in an optical lattice. The two components of the superposition can differ by of order 300 eV in energy, allowing tests of energy decoherence models with greatly improved sensitivity. We take into account the effects of higher-order nonlinearities, spatial inhomogeneity of the interaction, decay from the…

Entangled state fusion with Rydberg atoms
TLDR
A scheme for preparation of large-scale entangled GHZ states and W states with neutral Rydberg atoms with prominent advantage is that both two multiparticle GHz states and two multiparticles W states can be fused in this model, especially the success probability for fusion ofGHZ states can reach unit.

Theory of long-range interactions for Rydberg states attached to hyperfine-split cores
The theory is developed for one and two atom interactions when the atom has a Rydberg electron attached to a hyperfine split core state. This situation is relevant for some of the rare earth and
Long-lived Bell states in an array of optical clock qubits
The generation of long-lived entanglement on an optical clock transition is a key requirement to unlocking the promise of quantum metrology. Arrays of neutral atoms constitute a capable quantum

Fast multi-qubit gates by adiabatic evolution in interacting excited state manifolds.
Quantum computing and quantum simulation can be implemented by concatenation of one- and two-qubit gates and interactions. For most physical implementations, however, it may be advantageous to
