Exploring the Periodic Table of Superconducting Qubits

Superconducting qubits are a leading platform for realizing quantum computers, offering a diverse landscape of designs tailored to specific applications. This talk will explore this 'periodic table' of superconducting qubits, beginning with a review of superconducting circuit elements and the transmon qubit. Using the fluxonium qubit we will show how the addition of extra elements can lead to new capabilities. Next, we'll briefly explore emerging paradigms, qubits such as cat, dual-rail, and zero-pi qubits, which encode information in correlations rather than the presence or absence of excitations, offering potential advantages for fault tolerance. Beyond individual qubit designs, the talk will close with critical challenges and research opportunities as we build scalable quantum computing architectures.
