Modular Superconducting Qubit Architecture with a Multi-chip Tunable Coupler
Mark Field, Angela Q. Chen, Ben Scharmann +7
We use a floating tunable coupler to mediate interactions between qubits on separate chips to build a modular architecture. We demonstrate three different designs of multi-chip tun…
Full control of superconducting qubits with combined on-chip microwave and flux lines
Riccardo Manenti, Eyob A. Sete, Angela Q. Chen +7
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 sup…
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-…
Manufacturing low dissipation superconducting quantum processors
Ani Nersisyan, Stefano Poletto, Nasser Alidoust +10
Enabling applications for solid state quantum technology will require systematically reducing noise, particularly dissipation, in these systems. Yet, when multiple decay channels a…
General method for extracting the quantum efficiency of dispersive qubit readout in circuit QED
C. C. Bultink, B. Tarasinski, N. Haandbaek +5
We present and demonstrate a general three-step method for extracting the quantum efficiency of dispersive qubit readout in circuit QED. We use active depletion of post-measurement…
