Superconducting parametric amplifier
Technology Introduction:
Quantum amplifiers are vital for high-fidelity, multiplexed, single-shot qubit readout. This Taiwan-based project develops superconducting parametric amplifiers (PAs) across four subprojects: two focus on traveling-wave designs using Josephson junctions (Nb/Al) or ultrathin NbN for junction-free fabrication; one targets wafer-scale aluminum JPAs with quantum-limited noise; and one designs amplifiers for semiconductor-spin qubits. Co-developed with qubit teams, these amplifiers enhance scalability, control precision, and readout performance.
