DESCRIPTION:Nanotubes are attractive materials for electron spin qubits be
 cause they can be made free of hyperfine dephasing and because spin-orbit 
 interaction offers a route to all-electrical spin control. I will describe
  the first qubit in this material\, the valley-spin qubit. The qubit is co
 ntrolled by exploiting spin-orbit coupling in a bent nanotube and read out
  electrically using a generalization of Pauli blockade in a double quantum
  dot. I will also discuss prospects for studying spin-phonon coupling at t
 he single-quantum level in a suspended vibrating nanotube\, where the low 
 mass and high quality factor of the nanotube are expected to lead to large
  zero-point motion and long-lived quantum states
