For transfering data it would be in theory possible. I haven't heard anything about semiconducting properties in graphene or other forms of carbon.

Minimally, a graphene based classical (or quantum) computer would require transistors and traces on a carbon wafer, from which NAND gates and better could be constructed. FWIU there is certainly semiconductivity in graphene and there is also superconductivity in graphene at room temperature. And traces can be lased into clothing, fruit peels, and probably carboniferous wafers. Which electronic components cannot be made from graphene or other forms of carbon?

  I think its not the problem of if, but of how. graphene is delicate and can easily break. The manufacturing process is so hard that its still cheaper to use silicon to make chips
