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…
I solved it numerically. x=4 or x=0
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…
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…
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…
