Electrically detected magnetic resonance of As magnetic clock transitions in silicon
Ravi Acharya, Shao Qi Lim, Brett C. Johnson +9
Magnetic clock transitions (CTs), defined by vanishing first-order sensitivity of the transition frequency to magnetic field fluctuations, provide a powerful route to suppress deco…
Electron readout contrast enhancement in the parallel nuclear regime of an exchange-coupled donor spin qubit system
Holly G. Stemp, Mark R. van Blankenstein, Benjamin Wilhelm +10
Recent experiments on donor-based spin qubits in silicon have leveraged the exchange interaction between electrons bound to separate donor nuclei to perform two-qubit operations. A…
A silicon spin vacuum: isotopically enriched silicon-on-insulator and silicon from ultra-high fluence ion implantation
Shao Qi Lim, Brett C. Johnson, Sergey Rubanov +7
Isotopically enriched silicon (Si) can greatly enhance qubit coherence times by minimizing naturally occurring Si which has a non-zero nuclear spin. Ultra-high fluence $^{28…
