Probing Residual Noise at a Decoherence Sweet Spot in a Si/SiGe Spin Qubit
Shinwoo Lee, Hanseo Sohn, Jaemin Park +7
In Si/SiGe spin qubits with micromagnets, the longitudinal stray field gradient transduces charge noise into qubit frequency noise and limits coherence. We compare two neigh…
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…
Interplay of Electric Dipole Spin Resonance and Multilevel Landau-Zener Interference in p-Type Silicon Quantum Dots
Sayyid Irsyadul Ibad, Yusaku Suzuki, Masahiro Tadokoro +8
In this work, we examine microwave responses of the Pauli spin blockade (PSB) leakage current through a p-type silicon double quantum dot. We observe more than the expected two res…
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…
