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…
