Quantum Error Correction
IBM Quantum has a clear roadmap to practical quantum advantage in the coming years. This goal requires scalable, error-corrected quantum systems. We develop bottom-up approaches to the problem of noisy qubits and incorporate error correction techniques to realize this technology’s true potential.
