Grover search algorithm with Rydberg-blockaded atoms: Quantum Monte Carlo simulations
David Petrosyan, Mark Saffman, Klaus Mølmer
We consider the Grover search algorithm implementation for a quantum register of size using k (or k +1) microwave- and laser-driven Rydberg-blockaded atoms, following the…
Improved error thresholds for measurement-free error correction
Daniel Crow, Robert Joynt, Mark Saffman
Motivated by limitations and capabilities of neutral atom qubits, we examine whether measurement-free error correction can produce practical error thresholds. We show that this can…
Comparison of Gaussian and super Gaussian laser beams for addressing atomic qubits
Katharina Gillen-Christandl, Glen D. Gillen, M. J. Piotrowicz +1
We study the fidelity of single qubit quantum gates performed with two-frequency laser fields that have a Gaussian or super Gaussian spatial mode. Numerical simulations are used to…
Rydberg blockade, Förster resonances, and quantum state measurements with different atomic species
I. I. Beterov, M. Saffman
We calculate interspecies Rydberg-Rydberg interaction strengths for the heavy alkalis Rb and Cs. The presence of strong Förster resonances makes interspecies coupling a promising a…
A Rydberg blockade CNOT gate and entanglement in a 2D array of neutral atom qubits
K. M. Maller, M. T. Lichtman, T. Xia +5
We present experimental results on two-qubit Rydberg blockade quantum gates and entanglement in a two-dimensional qubit array. Without post selection against atom loss we achieve a…
Randomized benchmarking of single qubit gates in a 2D array of neutral atom qubits
T. Xia, M. Lichtman, K. Maller +4
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 fi…
