> I wonder why, the chip had 105 qubits and the error correction experiment used 101 qubits.

I wonder why, byte has 8 bits and the Hamming error correction code uses 7 bits.

oh right - that's because *the scheme* requires 3-7-15-... bits [0] and 7 is the largest that fits

Same with surface error correction - it's just the largest number in a list. No need for conspiracies. And no connection to manufacturing capabilities, which determine qubits on a single chip
