"…2nd discovery came from…a textbook from Dan Gottesman…work in progress…through a relatively obscure chapter, we found that we could realize our qudits as sets of qubits."

1024D #qudit (210 dimensions) can be mathematically represented as 10 #qubits (2×2×2... 10x)…to convert their constant-overhead protocol from qudits to qubits. The 10-qubit magic states were converted to standard single-qubit and three-qubit magic states with only a constant-factor overhead loss.
