   Graphene is a 2D material, like a sheet of paper. A carbon nanotube is more of a 1D material, like a pencil. Carbon nanotubes have (extremely) sharp points. A single wall carbon nanotube has a diameter of ±1.4nm. That is a lot smaller than

   For solid state qubits (spin/flux) you need: * e-beam lithography: expensive machine * high quality materials (GaAs 2DEG, or reproducible Josephson junctions): you need collaboration with other scientists * a huge supply of He4: money * a d

   For performing a quantum algorithm two sets of gates are needed, for instance single qubit rotations and a square root of swap gate. A hadamard gate is another example of a universal gate. Starting up your quantum computer, you will fi

   A grid of coupled qubits can be used to simulate quantum systems. A quantum system many physicists like to simulate is the Hubbard model ( http://en.wikipedia.org/wiki/Hubbard_model ) . A simulation of the Hubbard model can possibly lead to
