Superconducting spin qubits
are best qubits ever combining natural representation of two-level system in terms of electron spin with all advantages of superconducting qubits. This is discussed in our paper with Ciprian Padurariu submitted on cond-mat today. You will see it on Monday at http://arxiv.org/abs/0912.3910
For Ciprian, this is the first submission. It was difficult to work on the text, especially in last days. Anyway, we’ve this job done.
