Bus service for qubits: Spin-orbit qubits are right at home in electrical circuits

Qubit-based computing exploiting spooky quantum effects like entanglement and superposition will speed up factoring and searching calculations far above what can be done with mere zero-or-one bits. To domesticate quantum weirdness, however, to make it a fit companion for mass-market electronic technology, many tricky bi-lateral and multi-lateral arrangements—among photons, electrons, circuits, cavities, etc.—need to be negotiated.
