Amazon has introduced its first-ever quantum processor, dubbed Ocelot, designed specifically to reduce quantum error correction costs by up to 90% compared to existing approaches. The prototype chip uses "cat qubits" -- named after Schrodinger's cat thought experiment -- which intrinsically suppress certain types of quantum errors. Unlike conventional approaches that add error correction after designing the architecture, AWS built Ocelot with quantum error correction as the primary requirement. The chip consists of two stacked 1cm2 silicon microchips containing 14 core components: five data qubits, five buffer circuits for stabilization, and four qubits dedicated to error detection. Quantum computers are notoriously sensitive to environmental noise -- including vibrations, heat, and electromagnetic interference -- which disturbs qubits and generates computational errors. These errors multiply as quantum systems scale up, creating a significant barrier to practical quantum computing. Ocelot's high-quality oscillators, made from a thin film of superconducting Tantalum processed using specialized techniques developed by AWS material scientists, generate the repetitive electrical signals that maintain quantum states. "We're just getting started and we believe we have several more stages of scaling to go through," said Oskar Painter, AWS director of Quantum Hardware, whose team published their findings in Nature. Industry analyst Heather West of IDC was more measured, categorizing Ocelot as "much more of an advancement and less of a breakthrough," noting that superconducting qubits designed to resist certain error types aren't completely novel.Read more of this story at Slashdot.
