Precise 2D electric field density simulations for superconducting quantum devices
Zydrunas Gimbutas, Wei-Ren Syong, Nhi Nguyen +5
Dielectric loss due to two-level systems is a limiting factor for superconducting qubit relaxation times. These losses arise mostly from nanometer-scale interfacial defect regions…
Effective reflection mode measurement for hanger-coupled microwave resonators
John R. Pitten, Nicholas Materise, Wei-Ren Syong +3
Superconducting microwave resonators are used in many low-power applications, such as the study of two-level system loss in superconducting quantum devices. Fano asymmetry, charact…
High-Throughput Microwave Package for Precise Superconducting Device Measurement
Wei-Ren Syong, Allie Miller, Emma Davis +6
Cryogenic microwave measurement of superconducting quantum devices is complicated by the packaging required to connect devices to control and readout circuitry. In this work, we ou…
Loss tangent fluctuations due to two-level systems in superconducting microwave resonators
André Vallières, Megan E. Russell, Xinyuan You +10
Superconducting microwave resonators are critical to quantum computing and sensing technologies. Additionally, they are common proxies for superconducting qubits when determining t…
