This topical review addresses how Rydberg atoms can serve as building blocks for
emerging quantum technologies. Whereas the fabrication of large numbers of artificial …

Quantum computing with atomic qubits and Rydberg interactions: progress and challenges

M Saffman - Journal of Physics B: Atomic, Molecular and Optical …, 2016 - iopscience.iop.org
We present a review of quantum computation with neutral atom qubits. After an overview of
architectural options and approaches to preparing large qubit arrays we examine Rydberg …

Experimental investigations of dipole–dipole interactions between a few Rydberg atoms

A Browaeys, D Barredo, T Lahaye - Journal of Physics B: Atomic …, 2016 - iopscience.iop.org
This review summarizes experimental works performed over the last decade by several
groups on the manipulation of a few individual interacting Rydberg atoms. These studies …

Single-atom trapping in holographic 2D arrays of microtraps with arbitrary geometries

F Nogrette, H Labuhn, S Ravets, D Barredo, L Béguin… - Physical Review X, 2014 - APS
We demonstrate single-atom trapping in two-dimensional arrays of microtraps with arbitrary
geometries. We generate the arrays using a spatial light modulator, with which we imprint an …

Randomized benchmarking of single-qubit gates in a 2D array of neutral-atom qubits

T Xia, M Lichtman, K Maller, AW Carr, MJ Piotrowicz… - Physical review …, 2015 - APS
We characterize single-qubit Clifford gate operations with randomized benchmarking in a
2D array of neutral-atom qubits and demonstrate global and site selected gates with high …

Quantum computing with neutral atoms

DS Weiss, M Saffman - Physics Today, 2017 - pubs.aip.org
In 1982 Richard Feynman conceived of a “quantum mechanical computer.” 1 His central
idea was that a quantum device could take advantage of quantum entanglement and …

Rapid production of uniformly filled arrays of neutral atoms

BJ Lester, N Luick, AM Kaufman, CM Reynolds… - Physical review …, 2015 - APS
We demonstrate rapid loading of a small array of optical tweezers with a single Rb 87 atom
per site. We find that loading efficiencies of up to 90% per tweezer are achievable in less …

Gray-molasses optical-tweezer loading: controlling collisions for scaling atom-array assembly

MO Brown, T Thiele, C Kiehl, TW Hsu, CA Regal - Physical Review X, 2019 - APS
To isolate individual neutral atoms in microtraps, experimenters have long harnessed
molecular photoassociation to make atom distributions sub-Poissonian. While a variety of …

Coherence and Rydberg blockade of atomic ensemble qubits

M Ebert, M Kwon, TG Walker, M Saffman - Physical Review Letters, 2015 - APS
We demonstrate| W⟩ state encoding of multiatom ensemble qubits. Using optically trapped
Rb atoms, the T 2 coherence time is 2.6 (3) ms for N¯= 7.6 atoms and scales approximately …

Atomic Fock state preparation using Rydberg blockade

M Ebert, A Gill, M Gibbons, X Zhang, M Saffman… - Physical Review Letters, 2014 - APS
We use coherent excitation of 3–16 atom ensembles to demonstrate collective Rabi flopping
mediated by Rydberg blockade. Using calibrated atom number measurements, we …
