Interaction of Strain and Nuclear Spins in Silicon: Quadrupolar Effects on Ionized Donors
Interaction of Strain and Nuclear Spins in Silicon: Quadrupolar Effects on Ionized Donors
The nuclear spins of ionized donors in silicon have become an interesting quantum resource due to their very long coherence times. Their perfect isolation, however, comes at a price, since the absence of the donor electron makes the nuclear spin difficult to control. We demonstrate that the quadrupolar interaction allows …
