Silicon-Germanium Heterostructures with Enhanced Valley Splitting for Spin Qubits
David W. Kanaar, Efrain Martinez, Peihong Zhang +1
Achieving valley splittings well in excess of the thermal energy of electrons and avoiding valley excitations is essential for the consistent initialization, operation and readout…

Fast charge noise sensing using a spectator valley state in a singlet-triplet qubit
David W. Kanaar, Yasuo Oda, Mark F. Gyure +1
Semiconductor spin qubits are a promising platform for quantum computing but remain vulnerable to charge noise. Accurate, in situ measurement of charge noise could enable closed-lo…
