The parent article is better at describing the engineering challenges. Amazing approach:

"MZMs are the building blocks of our qubits, storing quantum information through ‘parity’—whether the wire contains an even or odd number of electrons...How can we distinguish between, say, 1,000,000,000 and 1,000,000,001 electrons?..."
