Adding `Qit` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add Qit

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

Qit = "0.1.4"

The Qit library will be automatically available globally. Read the Qit library documentation.

Readme

Qit

Simple quantum computer simulator library without matrix operations.

Example

All gates can make changes to the qubit using the apply method.

Usage basic gates

use Qit::core::{Applicable, Operator, Qubits};
use Qit::gates::{CX, H, U, X, Z, OperatorVec, PushOps};

// 1-Bit Gate
let h_0 = H::new(0);
// create |0⟩ Qubit
let q_in = Qubits::zeros(1);
let q_out = h_0.apply(q_in);
q_out.print_cmps();
// |0⟩ : +0.707 +0.000i
// |1⟩ : +0.707 +0.000i

// 2-Bit Gate
let cx01 = CX::new(0, 1);
// q_in = |01⟩ Qubit
let q_in = Qubits::from_num(2, 1);
let q_out = cx01.apply(q_in);
q_out.print_cmps();
// |00⟩ : +0.000 +0.000i
// |01⟩ : +0.000 +0.000i
// |10⟩ : +0.000 +0.000i
// |11⟩ : +1.000 +0.000i

// Combine gates into one unitary gate
let x = X::new(0);
let cx01 = CX::new(0, 1);
let z = Z::new(1);
let mut circ = OperatorVec::new();
circ.push_ops(x);
circ.push_ops(cx01);
circ.push_ops(z);
let u = U::new(circ, String::from("example_circ"));

let q_in = Qubits::from_num(2, 0);
let q_out = u.apply(q_in);
q_out.print_cmps();
// |00⟩ : +0.000 +0.000i
// |01⟩ : +0.000 +0.000i
// |10⟩ : -0.000 -0.000i
// |11⟩ : -1.000 -0.000i

Usage prepared circuits

The circuits module implements a function that gives a circuit created using the structure of the gates module.

use Qit::circuits::wrapping_qsub_const;
use Qit::core::{Applicable, Qubits};
use Qit::gates::U;

let b = vec![0, 1, 2];
let sub_2 = wrapping_qsub_const(&b, 2);
let sub_3 = wrapping_qsub_const(&b, 3);

// combine sub_2 and sub_3
let sub_5 = U::new(
    vec![Box::new(sub_2), Box::new(sub_3)],
    String::from("sub_5"),
);
// q_in = |111⟩
let q_in = Qubits::from_num(3, 7);
let q_out = sub_5.apply(q_in);

q_out.print_cmps();
// |000⟩ : +0.000 +0.000i
// |001⟩ : +0.000 +0.000i
// |010⟩ : +1.000 +0.000i
// |011⟩ : +0.000 +0.000i
// |100⟩ : +0.000 +0.000i
// |101⟩ : +0.000 +0.000i
// |110⟩ : +0.000 +0.000i
// |111⟩ : +0.000 +0.000i

Current version: 0.1.3
