Increasing valley splitting in Si/SiGe by practically achievable heterostructure profiles
Lukas Cvitkovich, Peter Stano, Dominique Bougeard +2
Silicon spin qubits are marred by the valley degeneracy of the conduction band. In a nanodevice, the degeneracy is lifted by interfaces and alloy disorder, but the resulting valley…

Disorder-independent hole spin manipulation by hopping
Biel Martinez, Ana Sempere-Sanchis, José C. Abadillo-Uriel +1
Spin manipulation by hopping has recently emerged as a promising strategy to control hole spins in quantum dots using exclusively baseband control, thereby mitigating power dissipa…
