Amazon Web Services has announced a significant breakthrough in quantum computing with the introduction of their new Ocelot chip. Developed at the AWS Center for Quantum Computing at the California Institute of Technology, this chip promises to reduce the costs of implementing quantum error correction by up to 90%. The Ocelot chip uses cat qubit technology, inspired by Schrödinger’s cat thought experiment, to suppress certain types of errors intrinsically.
This innovative approach reduces the resources required for quantum error correction, making the technology more scalable and cost-effective. Oskar Painter, AWS Director of Quantum Hardware, stated, “With recent advancements in quantum research, it is no longer a matter of if, but when practical, fault-tolerant quantum computers will be available for real-world applications. Ocelot is an important step on that journey.”
One of the biggest challenges in building quantum computers is their sensitivity to environmental changes, which can cause errors in quantum computations.
Traditionally, quantum error correction has been incredibly resource-intensive, making it costly and impractical. However, Ocelot’s new architecture was designed from the ground up with error correction as a priority. “Scaling Ocelot to a fully functional quantum computer capable of societal impact would require as little as one-tenth of the resources associated with standard quantum error correction approaches,” Painter added.

Quantum computers have the potential to revolutionize various fields, from drug discovery and the development of new materials to more accurate financial market predictions. AWS remains committed to investing in quantum research and refining its quantum computing approach.
For now, quantum computing enthusiasts and researchers can explore quantum computing with Amazon Braket, a fully managed AWS service that provides access to diverse quantum computing hardware and software tools. Ocelot is a prototype quantum computing chip designed to test AWS’s quantum error correction architecture. It consists of two integrated silicon microchips, each with an area of roughly 1cm².
The chips are bonded in an electrically-connected stack, with superconducting materials forming the quantum circuit elements. The Ocelot chip includes 14 core components: five cat qubits, five buffer circuits, and four additional qubits for error detection. The cat qubits store quantum states using high-quality oscillators made from Tantalum.
AWS continues to promote innovation in quantum computing, aiming to turn science fiction into science fact, and Ocelot is a promising step forward in this endeavor.
