Coherence protection of a silicon hole spin qubit with phase-modulated microwave driving
Sayyid I. Ibad, Yusuke Sato, Takuma Kuno +8
Hole spins in silicon quantum dots are a promising platform for quantum computing due to their strong intrinsic spin-orbit coupling (SOC), which enables fast, all-electrical contro…
Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot
Xunyao Luo, Xander Peetroons, Tsung-Yeh Yang +27
Electron spin resonance spectroscopy (ESR) of a single electron in planar Si-MOS quantum dot is reported in the vicinity of a valley level anti-crossing. A number of one and two-ph…
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…
