Quantum computing startup says it will beat IBM to error correction
Company builds on recent demonstration of error-tracking in similar hardware.
Current qubits, regardless of their design, are prone to errors during measurements, operations, or even when simply sitting there. Transmons are relatively simple to control, and their quality has been improving iteratively as companies get experience with fabricating devices. Unlike transmons, atoms do not suffer from device-to-device variations, and they're incredibly compact—many thousands can potentially be held in a square centimeter.
