Quantum support vector machines for classification and regression on a trapped-ion quantum computer
Teppei Suzuki, Takashi Hasebe, Tsubasa Miyazaki
Quantum machine learning is a rapidly growing field at the intersection of quantum computing and machine learning. In this work, we examine our quantum machine learning models, whi…
Ground test results of the micro-vibration interference for the x-ray microcalorimeter onboard XRISM
Takashi Hasebe, Ryuta Imamura, Masahiro Tsujimoto +8
Resolve is a payload hosting an X-ray microcalorimeter detector operated at 50 mK in the X-Ray Imaging and Spectroscopy Mission (XRISM). It is currently under development as part o…
Tensor-to-scalar ratio forecasts for extended LiteBIRD frequency configurations
U. Fuskeland, J. Aumont, R. Aurlien +114
LiteBIRD is a planned JAXA-led CMB B-mode satellite experiment aiming for launch in the late 2020s, with a primary goal of detecting the imprint of primordial inflationary gravitat…
Testbed preparation of a small prototype polarization modulator for LiteBIRD low-frequency telescope
Thuong D. Hoang, Tomotake Matsumura, Ryota Takaku +9
LiteBIRD is the Cosmic Microwave Background (CMB) radiation polarization satellite mission led by ISAS/JAXA. The main scientific goal is to search for primordial gravitational wave…
Testing magnetic interference between TES detectors and the telescope environment for future CMB satellite missions
Tommaso Ghigna, Thuong Duc Hoang, Takashi Hasebe +11
The two most common components of several upcoming CMB experiments are large arrays of superconductive TES (Transition-Edge Sensor) detectors and polarization modulator units, e.g.…
Probing Cosmic Inflation with the LiteBIRD Cosmic Microwave Background Polarization Survey
LiteBIRD Collaboration, E. Allys, K. Arnold +188
LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and…
A Large Diameter Millimeter-Wave Low-Pass Filter Made of Alumina with Laser Ablated Anti-Reflection Coating
Ryota Takaku, Qi Wen, Scott Cray +14
We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) made with laser-ablated sub-wavelength structures (SWS). The filter has be…
