American quantum computing startup PsiQuantum announced yesterday that it has cracked a significant puzzle on the road to making the technology useful: manufacturing quantum chips in useful quantities.

Dubbed Ocelot, it’s designed to correct errors with less hardware overhead.

Amazon is making its foray into quantum computing with the launch of a new chip designed to make quantum error correction more efficient. In an announcement on Thursday, Amazon Web Services (AWS) said the chip, called Ocelot, can “reduce the costs of implementing quantum error correction by up to 90%, compared to current approaches.”
