Switchable Next-Nearest-Neighbor Coupling for Controlled Two-Qubit Operations
Switchable Next-Nearest-Neighbor Coupling for Controlled Two-Qubit Operations
Minimizing gate depth is important for extending the computational power of a noisy quantum processor, and native multiqubit gates could dramatically reduce the gate depth of generic circuits. To that end, although various approaches have been proposed, practical realization may be hindered by stringent control requirements, or by poor compatibility …
