Concatenated continuous driving of silicon qubit by amplitude and phase modulation
Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +22
The rate of coherence loss is lower for a qubit under the Rabi drive than a freely evolving qubit . Building on this principle, concatenated continuous d…

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…
