Mark Saffman "Quantum computing with atomic qubit arrays"

Abstract

Quantum computing with atomic qubit arrays
Large arrays of neutral atoms are a leading modality in the race towards useful
quantum computation. Systems with more than 1000 qubits in 2D arrays and gate
fidelities approaching three nines are being developed by many academic and
industrial groups. I will present recent progress at University of Wisconsin-Madison
and Infleqtion with physical and logical qubit encodings. Interesting challenges
remain in scaling the size and performance to the levels needed for quantum utility.
Ultimately a modular approach to quantum computation will enable scaling to
millions of qubits, with inter-module connections enabled by photonic links.
Preliminary results on entangling atoms with photons for scaling a modular
architecture will be presented.
