A 0.74-mW K-band Cryogenic SiGe LNA in 130-nm BiCMOS with 14-K Noise Temperature for Scalable Quantum Readout
Xiuhan Chen, Haoling Li, Gun Suer +4
This paper presents a sub-milliwatt K-band cryogenic low-noise amplifier (LNA) implemented in GlobalFoundries (GF) 130CBIC SiGe BiCMOS, intended for a sub-Kelvin qubit readout…
Nontrivial Boundary-Mediated Superconducting Transport in a TRSB Topological Iron-Based Superconductor
Wenyao Liu, Gabriel Natale, Camron Farhang +22
The interplay of superconductivity, band topology, and spontaneous time-reversal-symmetry breaking (TRSB) is expected to enable topological superconducting boundary states. FeTe0.5…
An ultra-broadband axion dark matter experiment
Angelo Esposito, Kin Chung Fong, Lam Hui
We propose a novel broadband strategy to search for axions by leveraging observables controlled by the axion field squared. We present a practical implementation of this concept fo…
Measuring Reactive-Load Impedance with Transmission-Line Resonators Beyond the Perturbative Limit
Xuanjing Chu, Jinho Park, Jesse Balgley +8
We develop an analytic framework to extract circuit parameters and loss tangent from superconducting transmission-line resonators terminated by reactive loads, extending analysis b…
Direct Digital-to-Physical Synthesis: From mmWave Transmitter to Qubit Control
Najme Ebrahimi, Haoling Li, Gun Suer +2
The increasing demand for high-speed wireless connectivity and scalable quantum information processing has driven parallel advancements in millimeter-wave (MMW) communication trans…
Observing unconventional superconductivity via kinetic inductance in Weyl semimetal MoTe
Mary Kreidel, Julian Ingham, Xuanjing Chu +10
Identifying the pairing symmetry of unconventional superconductors plays an essential role in the ongoing quest to understand correlated electronic matter. A long-standing approach…
