RippleCarryCGAddLE operation

Fully qualified name: Microsoft.Quantum.Unstable.Arithmetic.RippleCarryCGAddLE

operation RippleCarryCGAddLE(xs : Qubit[], ys : Qubit[], zs : Qubit[]) : Unit is Adj

Summary

Sets a zero-initialized little-endian register zs to the sum of little-endian registers xs and ys using the ripple-carry algorithm.

Description

Computes zs := xs + ys + zs[0] modulo 2ⁿ, where xs, ys, and zs are little-endian registers, Length(xs) = Length(ys) ≤ Length(zs) = n, assuming zs is 0-initialized, except for maybe zs[0], which can be This operation uses the ripple-carry algorithm. NOTE: zs[Length(xs)] can be used as carry-out, if zs is longer than xs.
