Module statevector 

N-qubit statevector simulator

Represents quantum states as dense complex amplitude vectors of size 2^n, and applies single- and two-qubit gates exactly.

Structs

Statevector

N-qubit statevector: stores 2^n complex amplitudes as (re, im) pairs.

Functions

cabs2

Complex magnitude squared: |z|² = re² + im²

cadd

Complex add: (a+ib) + (c+id) = (a+c) + i(b+d)

cmul

Complex multiply: (a+ib)(c+id) = (ac-bd) + i(ad+bc)
