Quantum computing startup QuEra Computing and Amazon Web Services have announced an expanded multi-year strategic partnership with a clear target: deliver the world's first fault-tolerant quantum computers by 2028, according to a PR Newswire announcement from QuEra.
The two companies say the machines will be made available through Amazon Braket, AWS's cloud-based quantum computing service. According to SiliconANGLE, AWS has committed to making fault-tolerant quantum computing accessible on its platform within the next two years.
Fault tolerance is the holy grail of quantum computing. Today's quantum machines are plagued by errors — qubits, the quantum equivalent of classical computing bits, are extremely fragile and prone to interference from their environment. Error rates are high enough that current systems, often called NISQ (noisy intermediate-scale quantum) devices, can only run shallow, limited computations before mistakes accumulate and corrupt results. A fault-tolerant machine would correct errors on the fly, unlocking far more powerful and reliable computations.
New Scientist frames the announcement with a pointed question: are useful, error-free quantum computers really only two years away? The implication is that this timeline, while ambitious, is now being backed by the resources and cloud infrastructure of one of the world's largest technology companies.
QuEra uses neutral-atom technology to build its quantum processors, an approach that has shown promise for scaling error correction. Integrating that hardware with AWS's global cloud reach would make fault-tolerant quantum power broadly accessible to researchers, pharmaceutical companies, financial institutions, and others — without requiring anyone to own or operate the exotic hardware themselves.
If the 2028 target holds, it could mark the moment quantum computing moves from a laboratory curiosity to a commercially viable tool, fundamentally changing what problems computers can solve.
