Confinement drives valley splitting above 4K in buried silicon quantum wells
Davide Degli Esposti, Emma Catherine Brann, Asser Elsayed +3
Controlling the energy scales of a quantum system is essential for defining robust qubits. In silicon spin qubits, the nearly degenerate conduction-band valleys create a leakage ch…

Valley Splitting Correlations Across a Silicon Quantum Well Containing Germanium
Jonathan C. Marcks, Emily Eagen, Emma C. Brann +12
Quantum dots in SiGe/Si/SiGe heterostructures host coherent electron spin qubits, which are promising for future quantum computers. The silicon quantum well hosts near-degenerate e…
