The basic steps of quantum information processing are relatively straightforward, at least on paper: Prepare qubits in an appropriate initial state, let them evolve under the influence of one‐ and two‐qubit gate operations, and read out the results. But obtaining scalable physical implementations of these steps continues to challenge researchers, in part because of the conflicting requirements of ensuring sufficient isolation from the environment to maintain qubit coherence and allowing sufficient coupling between qubits to enable the requisite two‐qubit operations.
