"speed enables measurements/ corrections before compounding error rates reduce accuracy/ reliability... 10X faster nonlinear light-matter coupling... quarton coupler superconducting circuit turns 1 qubit into resonator and use other qubit as artificial atom storing quantum information transferred as microwave photons... future: adding additional electronic components, such as filters, producing readout circuit that could be incorporated into larger quantum system... rapidly simulate new materials, faster machine-learning models"
