In quantum computing, robustness against noise is a primary concern. Meanwhile, geometric (topological) phases in physical systems are determined by global properties that are insensitive to the details of evolution, and thus offer some built-in noise resilience. Marrying these ideas for superconducting qubits is not easy, but this study details a scalable scheme for fast holonomic quantum computation based on superconducting circuits with all-resonant microwave control. The main difficulties for physical implementation in this context are overcome, with both single-qubit and nontrivial two-qubit gates being described.
