High Fidelity Qubit Control in a Natural Si-MOS Quantum Dot using a 300 mm Silicon on Insulator Wafer
Xander Peetroons, Xunyao Luo, Tsung-Yeh Yang +26
We demonstrate high-fidelity single qubit control in a natural Si-MOS quantum dot fabricated in an industrial 300 mm wafer process on a silicon on insulator (SOI) wafer using elect…
Robust spin-qubit control in a natural Si-MOS quantum dot using phase modulation
Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +13
Silicon quantum dots are one of the most promising candidates for practical quantum computers because of their scalability and compatibility with the well-established complementary…
Thermal circuit model for silicon quantum-dot array structures
Takeru Utsugi, Nobuhiro Kusuno, Takuma Kuno +7
Temperature rise of qubits due to heating is a critical issue in large-scale quantum computers based on quantum-dot (QD) arrays. This leads to shorter coherence times, induced read…
Multi-TeV Gamma-Ray Flares from Markarian 421 in 2000 and 2001 Observed with the Tibet Air Shower Array
M. Amenomori
Several strong TeV gamma-ray flares were detected from Markarian 421 in the years 2000 and 2001 by the Tibet III air shower array at a level of statistical significance of 5.1 sigm…
