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…
Characterization of Nb films for superconducting qubits using phase boundary measurements
Kevin M. Ryan, Carlos G. Torres-Castanedo, Dominic P. Goronzy +8
Continued advances in superconducting qubit performance require more detailed understandings of the many sources of decoherence. Within these devices, two-level systems arise due t…
Contactless Excitation of Acoustic Resonance in Insulating Wafers
Gan Zhai, Yizhou Xin, Cameron J. Kopas +7
Contactless excitation and detection of high harmonic acoustic overtones in a thin insulator single crystal are described using radio frequency spectroscopy techniques. Single crys…
Multi-modal electron microscopy study on decoherence sources and their stability in Nb based superconducting qubit
Jin-Su Oh, Xiaotian Fang, Tae-Hoon Kim +14
Niobium is commonly used for superconducting quantum systems as readout resonators, capacitors, and interconnects. The coherence time of the superconducting qubits is mainly limite…
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…
Temperature dependent nucleation and annihilation of individual magnetic vortices
G. Mihajlovic, M. S. Patrick, J. E. Pearson +5
We studied the temperature dependence of the magnetization reversal in individual submicron permalloy disks with micro-Hall and bend-resistance magnetometry. The nucleation field e…
