Scientists are tackling one of the biggest hurdles in quantum computing: errors caused by noise and interference. Their solution? A new chip called Ocelot that uses "cat qubits" — a special type of qubit that dramatically reduces errors.

Amazon on Thursday unveiled its first quantum computing chip, about a week after rival Microsoft announced its first one devoted to the nascent technology.

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.”

AWS has launchd Ocelot, its first quantum computing chip, bringing it into line with its big cloud rivals Microsoft and Google.

Following Google and Microsoft’s quantum computing announcements, the tech giant says its new chip will lead to more reliable quantum computers.

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.
