A new quantum ripple-carry addition circuit

TLDR
In this paper, a linear-depth ripple-carry quantum addition circuit with only a single ancillary qubit has been proposed, which has lower depth and fewer gates than previous ripple carry adders.
Abstract
We present a new linear-depth ripple-carry quantum addition circuit. Previous addition circuits required linearly many ancillary qubits; our new adder uses only a single ancillary qubit. Also, our circuit has lower depth and fewer gates than previous ripple-carry adders.

Fast quantum modular exponentiation architecture for Shor's factoring algorithm

TL;DR: A novel and efficient, in terms of circuit depth, design for Shor's quantum factorization algorithm, which effectively utilizes a diverse set of adders based on the Quantum Fourier transform Draper's adders to build more complex arithmetic blocks: quantum multiplier/accumulators by constants and quantum dividers by constants.

Quantum networks for elementary arithmetic operations.

TL;DR: This work provides an explicit construction of quantum networks effecting basic arithmetic operations: from addition to modular exponentiation, and shows that the auxiliary memory required to perform this operation in a reversible way grows linearly with the size of the number to be factorized.

A logarithmic-depth quantum carry-lookahead adder

TL;DR: This work reduces the cost of addition dramatically with only a slight increase in the number of required qubits, and can be used within current modularmultiplication circuits to reduce substantially the run-time of Shor's algorithm.
