Abstract: For qubits based on donor nuclear or electron spins in the solid state, single-spin detection for readout remains a crucial unsolved problem. We analyze the Kane adiabatic scheme based on spin-dependent electron tunnelling between individual donor atoms, detected electrically using a single electron transistor (SET). Despite stabilization due to the presence of the ${\mathrm{D}}^{+},$ the field strengths required place severe constraints on the SET measurement time. We propose a new method based on resonant electron transfer at low field strengths, and discuss various implementation issues.
