Module core

Expand description

Qubit struct used for simulation and complex number struct that composes it.

In this library, qubits are represented by vectors of complex numbers, and gates are defined as structs that change vectors of complex numbers. “gates” has basic 1-bit operators such as H, Z, Y, and Z, 2-bit operators such as CX, and a struct that uses them all as one operator.

§Example usage

use Qit::{circuits::wrapping_qadd_const, core::{Qubits, Applicable}};
let q_in = Qubits::from_num(3, 4);
// q_in = |0100⟩
let add = wrapping_qadd_const(&vec![0, 1, 2], 3);
// add * |b⟩ = |b + 3⟩
let q_out = add.apply(q_in);
q_out.print_cmps();
// |000⟩ : +0.000 +0.000i
// |001⟩ : +0.000 +0.000i
// |010⟩ : +0.000 +0.000i
// |011⟩ : +0.000 +0.000i
// |100⟩ : +0.000 +0.000i
// |101⟩ : +0.000 +0.000i
// |110⟩ : +0.000 +0.000i
// |111⟩ : +1.000 +0.000i

Modules§
