“the first quantum processor where error-corrected qubits get exponentially better as they get bigger”
Achieving this turns the normal problem of scaling quantum computation upside down.

It also breaks a fundamental law of quantum theory, that the bigger a system in a quantum state is, the faster it collapses, exponentially so. Which should at least tell you to take Google's announcement with z grain of salt.

Hmm why? I thought the whole idea was this would work eventually. Physical qubit vs logical qubit distinction is there already for a long time.
The scaling problem is multifaceted. IMHO the physical qubits are the biggest barrier to scaling.
