Reducing charge noise in quantum dots by using thin silicon quantum wells
B. Paquelet Wuetz, D. Degli Esposti, A. M. J. Zwerver +7
Charge noise in the host semiconductor degrades the performance of spin-qubits and poses an obstacle to control large quantum processors. However, it is challenging to engineer the…
