At some level, this is marketing hype. They have NOT "solved" quantum computing in the sense that a layman would expect: room temperature quantum integrated circuit able to give exponential speedup over classical algorithms. I would say the biggest innovation here is that they have made a silicon based integrated circuit with fault-tolerant qbits (using error-correction codes they invented).
