Amazon Web Services unveils Ocelot quantum computing chip

Amazon Web Services has unveiled its Ocelot chip based on a hardware-efficient quantum computing architecture. Fernando Brandão and Oskar Painter of AWS said in a blog post that the pair of silicon microchips that compose the Ocelot logical-qubit memory chip represent the company’s first-generation quantum chip, and it could reduce the costs of implementing quantum error correction by up to 90%. Ocelot represents Amazon Web Services’ pioneering effort to develop, from the ground up, a hardware implementation of quantum error correction that is both resource efficient and scalable. Based on superconducting quantum circuits, Ocelot achieves the following major technical advances. It is the first realization of a scalable architecture for bosonic error correction, surpassing traditional qubit approaches to reducing error-correction overhead. It is the first implementation of a noise-biased gate—a key to unlocking hardware-efficient error correction necessary to build scalable, commerc ... Read full article.
