The remarkable prospect for quantum-dot-coupled tin qubits in silicon

Wayne M. Witzel, Jesse J. Lutz, Dwight R. Luhman

Spin-$\frac{1}{2}$ ${}^{119}$Sn nuclei in a silicon semiconductor could make excellent qubits. Nuclear spins in silicon are known to have long coherence times. Tin is isoelectronic w…
