Amazon announced they have developed their own quantum chip; the Ocelot.

This follows Microsoft's reveal last week of their Majorana 1.

'We believe that scaling Ocelot to a full-fledged quantum computer capable of transformative societal impact would require as little as one-tenth as many resources as common approaches, helping bring closer the age of practical quantum computing.'

'We believe that Ocelot's architecture, with its hardware-efficient approach to error correction, positions us well to tackle the next phase of quantum computing: learning how to scale.'
