In this post: why I expect the maximum achievable qubit quality to increase drastically in the next few years. In 2014, the John Martinis group at UCSB performed an experiment where they stored a classical bit using their quantum computer. They protected the bit with a 9 qubit quantum repetition code. The protected bit had a half life of roughly 100 microseconds. Clearly that’s not competitive with classical storage… but the goal of the experiment wasn’t to hit a high number. The goal was to per...
