Efficient Construction of a Control Modular Adder on a Carry-Lookahead Adder Using Relative-phase Toffoli Gates
Kento Oonishi, Tomoki Tanaka, Shumpei Uno +3
Control modular addition is a core arithmetic function, and we must consider the computational cost for actual quantum computers to realize efficient implementation. To achieve a l…

Quantum Addition Circuits and Unbounded Fan-Out
Yasuhiro Takahashi, Seiichiro Tani, Noboru Kunihiro
We first show how to construct an O(n)-depth O(n)-size quantum circuit for addition of two n-bit binary numbers with no ancillary qubits. The exact size is 7n-6, which is smaller t…
