A Higher radix architecture for quantum carry-lookahead adder
Abstract In this paper, we propose an efficient quantum carry-lookahead adder based on the higher radix structure. For the addition of two n-bit numbers, our adder uses $$O(n)-O(\frac{n}{r})$$ O ( n ) - O ( n r ) qubits and $$O(n)+O(\frac{n}{r})$$ O ( n ) + O ( n r ) T gates to get the correct answe...
