Inside the Endres Lab with a 6,100-Qubit Array

From the creator

Caltech physicists have created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in a grid by lasers. This milestone comes amid a rapidly growing race to scale up quantum computers. There are several approaches in development, including those based on superconducting circuits, trapped ions, and neutral atoms, as used in the new study. "This is an exciting moment for neutral-atom quantum computing," says Manuel Endres, professor of physics at Caltech. "We can now see a pathway to large error-corrected quantum computers. The building blocks are in place." Endres is the principal investigator of the research published today in Nature. Three Caltech graduate students led the study: Hannah Manetsch, Gyohei Nomura, and Elie Bataille. In this video, Manetsch gives a quick tour of the experiment and describes how the team used optical tweezers — highly focused laser beams — to trap thousands of individual cesium atoms in a grid.
