Quantum Error Correction Moves Beyond Breakeven (IMAGE) DOE/US Department of Energy Caption A logical qubit is embedded into the state space of a harmonic oscillator using the grid code, represented here by faces of the cube. Quantum error correction protects these grid states from corruption by a noisy environment, symbolized by the ray.
