Core Concepts
Integrating a geometric shunt inductor into a transmon qubit, creating an inductively shunted transmon (IST), can significantly reduce unwanted interactions with other qubits and enable faster, higher-fidelity two-qubit operations, paving the way for larger and more reliable superconducting quantum computers.
