Scalable architecture for dark photon searches: Superconducting-qubit proof of principle
Runqi Kang, Qingqin Hu, Xiao Cai +4
The dark photon is a well-motivated candidate of dark matter due to its potential to open the window of new physics beyond the Standard Model. A fundamental mass-range-sensitivity…
Titanium Nitride Film on Sapphire Substrate with Low Dielectric Loss for Superconducting Qubits
Hao Deng, Zhijun Song, Ran Gao +19
Dielectric loss is one of the major decoherence sources of superconducting qubits. Contemporary high-coherence superconducting qubits are formed by material systems mostly consisti…
Ultrahigh-inductance materials from spinodal decomposition
Ran Gao, Hsiang-Sheng Ku, Hao Deng +10
Disordered superconducting nitrides with kinetic inductance have long been considered a leading material candidate for high-inductance quantum-circuit applications. Despite continu…
Epitaxial titanium nitride microwave resonators: Structural, chemical, electrical, and microwave properties
Ran Gao, Wenlong Yu, Hao Deng +6
Titanium nitride is an attractive material for a range of superconducting quantum-circuit applications owing to its low microwave losses, high surface inductance, and chemical stab…
Magnetoplasmons in quasi-neutral epitaxial graphene nanoribbons
J. M. Poumirol, W. Yu, X. Chen +8
We present infrared transmission spectroscopy study of the inter-Landau-level excitations in quasi-neutral epitaxial graphene nanoribbon arrays. We observed a substantial deviation…
