Superconducting gatemon qubit could be the next quantum computing tech to scale to 50+ qubits | NextBigFuture.com

There have already been several quantum computer technologies that have scaled to 50-100 qubits. Gatemon superconducting qubits appear ready to scale to that level as well. Nature Nanotechnology – Superconducting gatemon qubit based on a proximitized two-dimensional electron gas Abstract – Superconducting gatemon qubits The coherent tunneling of Cooper pairs across Josephson junctions (JJs) generates a nonlinear inductance that is used extensively in quantum information processors based on superconducting circuits, from setting qubit transition frequencies and interqubit coupling strengths to the gain of parametric amplifiers for quantum-limited readout. The inductance is either set by tailoring the metal oxide dimensions of
