Amazon Unveils Ocelot Quantum Chip, Advancing Error Correction Technology

Amazon Web Services announced the Ocelot quantum processor, reducing quantum error correction costs by up to 90 percent, according to the company.
Ocelot is designed to handle error correction more efficiently, which AWS claims could reduce resources required by five to ten times compared to traditional methods.
Oskar Painter, AWS head of quantum hardware, stated that quantum error correction is crucial for practical quantum computers, emphasizing that Ocelot targets this challenge.
John Preskill, from Caltech, mentioned that while Ocelot shows promise, there is still a long way to go before achieving quantum utility that benefits the world.

Hardware-efficient quantum error correction via concatenated bosonic qubits

To solve problems of practical importance1,2, quantum computers probably need to incorporate quantum error correction, in which a logical qubit is redundantly encoded in many noisy physical qubits3–5. The large physical-qubit overhead associated with error correction motivates the search for more hardware-efficient approaches6–18. Here, using a superconducting quantum circuit19, we realize a logical qubit memory formed from the concatenation of …
