Long qubit coherence times are a prerequisite for quantum computing, and in this paper we will discuss measurements of spin coherence in silicon. The results are encouraging

Spinqubits in Carbon Peapods
"... Spin chains have the potential to provide the controlled interactions needed for quantum computing. Carbon is a candidate host for spin qubits because in 12C materials the small spinorbit coupling and absence of hyperfine coupling ensures long spin coherence times. Carbon peapods, that is, singlew ..."
