Watch a 44-minute lecture exploring the implementation of multi-qubit entangling interactions in superconducting circuits, focusing on the demonstration of a high-fidelity iToffoli three-qubit gate. Learn how microwave quantum control techniques enable single-step execution of complex multi-qubit operations, overcoming traditional limitations of pairwise interactions in fixed-frequency, fixed-coupling superconducting processors. Discover a novel approach that achieves over 98% fidelity by utilizing simultaneous, non-commuting pairwise entangling drives, offering practical solutions for quantum many-body simulation and quantum error correction applications in systems with limited connectivity.
