Heralded state preparation in a superconducting qubit
J. E. Johnson, C. Macklin, D. H. Slichter +4
We demonstrate high-fidelity, quantum nondemolition, single-shot readout of a superconducting flux qubit in which the pointer state distributions can be resolved to below one part…

Dispersive readout of a flux qubit at the single photon level
J. E. Johnson, E. M. Hoskinson, C. Macklin +3
A superconducting flux qubit is inductively coupled to a Superconducting QUantum Interference Device (SQUID) magnetometer, capacitively shunted to form a 1.294-GHz resonator. The q…

Interactions Between Rydberg-Dressed Atoms
J. E. Johnson, S. L. Rolston
We examine interactions between atoms continuously and coherently driven between the ground state and a Rydberg state, producing "Rydberg-dressed atoms." Because of the large dipol…
