Summary

Story summary

California Institute of Technology (Caltech) researchers have made a 6,100-qubit array of neutral-atom qubits.
The qubits use ultracold caesium atoms arranged in a grid and controlled by lasers.
Researchers aim to scale to a million qubits within the next decade to enable computations.
Experts say more tests are needed before this setup becomes an operational quantum computer.
