Measured into existence
Before anything touches Solana, the lab sends one job to IBM: a Hadamard gate on every working qubit of the chip, then a readout. The first 256 bits, mixed with a lab secret, seed the coin's mint key, so its address exists before the coin does. A fingerprint of the bits rides in the launch transaction as a memo; the machine, the job id and the raw readout stay public on the coin's page.
