Google’s quantum computer reached an error-correcting milestone

The computer’s accuracy improved as scientists used more qubits to fix mistakes

To shrink error rates in quantum computers, sometimes more is better. More qubits, that is.

The quantum bits, or qubits, that make up a quantum computer are prone to mistakes that could render a calculation useless if not corrected.
