Interactions Between Rydberg-Dressed Atoms [PDF]
Physical Review A, 2010 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 dipolar coupling between two Rydberg atoms, a small admixture of Rydberg ...

Collective quantum jumps of Rydberg atoms [PDF]
Physical Review Letters, 2011 We study an open quantum system of atoms with long-range Rydberg interaction, laser driving, and spontaneous emission. Over time, the system occasionally jumps between a state of low Rydberg population and a state of high Rydberg population.

Time-Optimal Two- and Three-Qubit Gates for Rydberg Atoms [PDF]
Quantum, 2022 We identify time-optimal laser pulses to implement the controlled-Z gate and its three qubit generalization, the C2Z gate, for Rydberg atoms in the blockade regime. Pulses are optimized using a combination of numerical and semi-analytical quantum optimal

Continuously tunable radio frequency electrometry with Rydberg atoms [PDF]
Applied Physics Letters, 2022 We demonstrate a continuously tunable electric field measurement based on the far off-resonant AC stark effect in a Rydberg atomic vapor cell. In this configuration, a strong far off-resonant field, denoted as a local oscillator (LO) field, acts as a ...

Error budgeting for a controlled-phase gate with strontium-88 Rydberg atoms [PDF]
Physical Review Research, 2022 We study the implementation of a high fidelity controlled-phase gate in a Rydberg quantum computer. The protocol is based on a symmetric gate with respect to the two qubits as experimentally realized by Levine et al [Phys. Rev. Lett. 123, 170503 (2019)],

Hardware-Efficient, Fault-Tolerant Quantum Computation with Rydberg Atoms [PDF]
Physical Review X, 2021 Neutral atom arrays have recently emerged as a promising platform for quantum information processing. One important remaining roadblock for the large-scale application of these systems is the ability to perform error-corrected quantum operations.
