= Modular trapped ion quantum computer
Trapped ion people acknowledge that they can't put a million qubits in on chip (TODO why) so they are already thinking of ways to entangle separate chips. Thinking is maybe the key word here. One of the propoesd approaches inolves optical links. <Universal Quantum> for example explicitly rejects that idea in favor of electric field link modularity.
