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.”

Several physicists say the lack of a peer-reviewed, detailed paper on Microsoft's work undermines its claims. The tech community is also skeptical.

With recent announcements of new quantum computing advancements, Microsoft, Amazon and Google have set a new countdown clock ticking on today’s encryption — now an even shorter race than expected.

Researchers have criticised Microsoft's new Majorana 1 quantum computer, saying it has made claims about the way it works that aren't fully backed up by scientific evidence
