An asymmetric and fast Rydberg gate protocol for entanglement outside of the blockade regime
Daniel C. Cole, Vikas Buchemmavari, Mark Saffman
We analyze a new Rydberg gate design based on the original protocol [Jaksch, et. al. Phys. Rev. Lett. {\bf 85}, 2208 (2000)] that is modified to enable high fidelity op…
Atom--photon Entanglement with a Single Trapped Cesium Atom
H. Hwang, J. Moon, F. Herzallah +3
We demonstrate atom--photon entanglement using a single cesium atom trapped in an optical tweezer. Entanglement is generated by resonant excitation and subsequent spontaneous decay…
Entangling gate performance and fidelity limits with neutral atom Förster resonances
S. A. Norrell, Y. Shen, M. Saffman +1
Neutral-atom entangling gates are commonly analyzed with a single effective Rydberg-pair state, but near Förster resonances the pair manifold contains resonantly coupled interactio…
Qubit syndrome measurements with a high fidelity Rb-Cs Rydberg gate
J. Miles, M. T. Lichtman, A. M. Scott +20
We demonstrate an inter-species entangling Rydberg gate between rubidium (Rb) and cesium (Cs) atoms with fidelity . The two-species atom array enables…
Deterministic carving of quantum states with Grover's algorithm
Omar Nagib, M. Saffman, K. Mølmer
We show that iteration of a few ( ) unitary steps of Grover's algorithm suffices to perfectly prepare a Dicke state of atoms in a cavity. We also show that a few…
Efficient preparation of entangled states in cavity QED with Grover's algorithm
Omar Nagib, M. Saffman, K. Mølmer
We propose to employ the amplification mechanism of Grover's search algorithm to efficiently prepare entangled states of an ensemble of qubits. The conditional change of sign emplo…
