Amazon unveils new 'Ocelot' quantum computing prototype chip after Google's Willow and Microsoft's Majorana 1

Amazon Web Services has unveiled ‘Ocelot’, its first prototype quantum computing chip on Thursday, February 28, with claims of reducing error correction costs by up to 90 per cent. This comes right on the heels of Microsoft's Majorana 1 quantum chip which was unveiled last week and Google's Willow quantum chip which came last December. Developed by the team at the AWS Center for Quantum Computing at the California Institute of Technology, Ocelot uses a special architecture which builds error correction into the whole system from the ground up, using what Amazon calls, the ‘cat qubit,’ according to its blog post. “In the future, quantum chips built according to the Ocelot architecture could cost as little as one-fifth of current approaches, due to the drastically reduced number of resources required for error correction.” "Concretely, we believe this will accelerate our timeline to a practical quantum computer by up to five years,” he added.
