Amazon unveils 'Ocelot' quantum chip to accelerate commercial quantum computing

Amazon Web Services (AWS) has announced the development of a new quantum computing chip, dubbed Ocelot, which it believes could shave up to five years off its timeline for building a commercially viable quantum computer.

The prototype, unveiled on Thursday alongside a peer-reviewed paper in Nature, represents a significant technological leap despite currently possessing only a fraction of the computing power required for a fully operational quantum system.

Quantum computers promise to perform calculations that would take conventional machines millions of years, potentially revolutionizing industries ranging from materials science to pharmaceuticals. However, the fragile nature of qubits—the fundamental building blocks of quantum computing—necessitates robust error correction mechanisms. Traditional industry estimates have held that around one million physical qubits are needed to produce a sufficient number of reliable logical qubits for practical computing tasks.

AWS’s Ocelot chip, however, employs an innovative "cat" qubit approach, inspired by Schrödinger’s famous thought experiment, which allows the system to yield one working logical qubit from just nine physical qubits. Oskar Painter, AWS Director of Quantum Hardware, explained that this breakthrough could eventually enable useful quantum computers to be built with only 100,000 physical qubits—a reduction by a factor of five to ten compared to conventional estimates.

Constructed using standard semiconductor techniques and the material tantalum, the current prototype serves as a proof-of-concept. Painter noted, “We hope to customize these techniques further, making improvements at the materials and processing levels that will simplify the underlying technology and accelerate our development timeline.”

The announcement comes as major industry players, including Google, Microsoft, and startup PsiQuantum, also make strides in the rapidly evolving field of quantum computing. AWS’s latest venture underscores its commitment to remaining at the forefront of quantum innovation as it races to transform theoretical promise into commercial reality.
