Inside Google's quantum computing breakthrough
Briefly

The Google Quantum AI team spent years improving their qubit design and fabrication procedures, scaling up from a handful of qubits to dozens, and honing their ability to manipulate many qubits at once.
This mind-boggling number exceeds known timescales in physics and vastly exceeds the age of the universe, lending credence to quantum computation occurring in many parallel universes.
