Hamiltonian Phase Error in Resonantly Driven CNOT Gate Above the Fault-Tolerant Threshold

Yi-Hsien Wu, Leon C. Camenzind, Akito Noiri +8

Because of their long coherence time and compatibility with industrial foundry processes, electron spin qubits are a promising platform for scalable quantum processors. A full-fled…

Spatial noise correlations beyond nearest-neighbor in Si/SiGe spin qubits

Juan S. Rojas-Arias, Akito Noiri, Peter Stano +8

We detect correlations in qubit-energy fluctuations of non-neighboring qubits defined in isotopically purified Si/SiGe quantum dots. At low frequencies (where the noise is stronges…
