Parametric-resonance entangling gates with a tunable coupler
Eyob A. Sete, Nicolas Didier, Angela Q. Chen +3
High-fidelity parametric gates have been demonstrated with superconducting qubits via rf flux modulation of the qubit frequency. The modulation however leads to renormalization of…

Floating tunable coupler for scalable quantum computing architectures
Eyob A. Sete, Angela Q. Chen, Riccardo Manenti +2
We propose a floating tunable coupler that does not rely on direct qubit-qubit coupling capacitances to achieve the zero-coupling condition. We show that the polarity of the qubit-…
