Adaptive Quantum Tomography in a Weak Measurement System with Superconducting Circuits
Hyeok Hwang, JaeKyung Choi, Eunseong Kim
Adaptive tomography has been widely investigated to achieve faster state tomography processing of quantum systems. Infidelity of the nearly pure states in a quantum information pro…
Spatially Modulated Superfluid State in Two-Dimensional He Films
Jaewon Choi, Alexey A. Zadorozhko, Jeakyung Choi +1
The second layer of He films adsorbed on a graphite substrate is an excellent experimental platform to study the interplay between superfluid and structural orders. Here, we re…
Effect of external electromagnetic radiation on the anomalous metallic behaviors in Ta thin films
Junghyun Shin, Sungyu Park, Eunseong Kim
We investigated transport characteristics of superconducting Ta thin films with three configurations in rf radiation filters; no filter, only room-temperature filters, and low-temp…
Frequency-dependent Study of Solid Helium-4 Contained in a Rigid Double-torus Torsional Oscillator
Jaewon Choi, Jaeho Shin, Euseong Kim
The rigid double-torus torsional oscillator (TO) is constructed to reduce any elastic effects in-herent to complicate TO structures, allowing explicit probing for a genuine superso…
Superfluid-like TO Responses in Rotating Solid Helium
Jaewon Choi, Tomoya Tsuiki, Daisuke Takahashi +4
The irrotational nature of superfluid helium was discovered through its decoupling from the container under rotation. Similarly, the resonant period drop of a torsional oscillator…
Simultaneous investigation of shear modulus and torsional resonance of solid 4He
Jaeho Shin, Jaewon Choi, Keiya Shirahama +1
We investigate the origin of a resonant period drop of a torsional oscillator (TO) containing solid He by inspecting its relation to a change in elastic modulus. To underst…
