Abstract:	Graphene quantum point contacts (G-QPC) combine switching operations with quantized conductance, which can be modulated by top and back gates. Here we use the conductance quantization to design and simulate multi-valued logic (MVL) circuits and, more specifically an adder. The adder comprises two G-QPCs connected in parallel. We compute the conductance of the adder for various inputs and show that Graphene MVL circuits are feasible.
