An error correction model is derived from a stochastic dynamic programming problem incorporating rational expectations. A parametric restriction is derived that ...

And that's not just true for Atom's hardware; similar things can be said for other error-correction demonstrations done on different machines. There are two ways to go beyond these current limits.

Using surface code for error-correction introduces enormous overhead requirements for systems at scale – millions of physical qubits are needed to collectively act as the thousands of logical ...
