What the article says around this equation
The follow-up result reported a distance-7 surface code with 0.143\% 0.003\% error per cycle of error correction, an error suppression factor of = 2.14 0.02 when increasing the code distance by two, and a logical qubit lifetime exceeding the best physical qubit’s lifetime by a factor of 2.4 0.3 [ 16 ] . That is a memory experiment at a single logical qubit. It is a genuine threshold crossing and it is not a computation.
