Improving the accuracy of circuit quantization using the electromagnetic properties of superconductors
Seong Hyeon Park, Gahyun Choi, Eunjong Kim +6
Recent advances in quantum information processing with superconducting qubits have fueled a growing demand for scaling and miniaturizing circuit layouts. Despite significant progre…
Characterization of Broadband Purcell Filters with Compact Footprint for Fast Multiplexed Superconducting Qubit Readout
Seong Hyeon Park, Gahyun Choi, Gyunghun Kim +6
Engineering the admittance of external environments connected to superconducting qubits is essential, as increasing the measurement speed introduces spontaneous emission loss to su…
Optical and Raman spectroscopies of 171Yb3+:Y2SiO5 hyperfine structure for application toward microwave-to-optical transducer
Hee-Jin Lim, Ga-Hyun Choi, Ki Suk Hong
This study analyzed the optical techniques for high resolution, low-noise spectroscopy of a hyperfine structure (HFS) made of ytterbium-isotope 171 ions (:$…
Wide Effective Work-Function Tuning of Al/SiO/Si Junction Achieved with Graphene Interlayer at Al/SiO Interface
Wonho Song, Jung-Yong Lee, Junhyung Kim +7
The effective work-function of metal electrode is one of the major factors to determine the threshold voltage of metal/oxide/semiconductor junction. In this work, we demonstrate ex…
Negative Fermi-level Pinning Effect of Metal/n-GaAs(001) Junction with Graphene Interlayer
Hoon Hahn Yoon, Wonho Song, Sungchul Jung +6
It is demonstrated that the electric dipole layer due to the overlapping of electron wavefunctions at metal/graphene contact results in negative Fermi-level pinning effect on the r…
