As the field of quantum computing progresses to larger-scale devices, multiplexing will be crucial to scale quantum processors. While multiplexed readout is common practice for superconducting devices, relatively little work has been reported about t

Parametric-resonance entangling gates with a tunable coupler

Autor: Sete, Eyob A., Didier, Nicolas, Chen, Angela Q., Kulshreshtha, Shobhan, Manenti, Riccardo, Poletto, Stefano

Publikováno v: Phys. Rev. Applied 16, 024050 (2021)

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 the bare qubit-qubit coupling, thereby reducing the gate speed. Here,

Floating tunable coupler for scalable quantum computing architectures

Autor: Sete, Eyob A., Chen, Angela Q., Manenti, Riccardo, Kulshreshtha, Shobhan, Poletto, Stefano

Publikováno v: Phys. Rev. Applied 15, 064063 (2021)

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-coupler couplings can be engineered to offset the otherwise constant q
