QML is the fusion of quantum computing and AI, where quantum circuits are used to improve machine learning algorithms. Some use cases include:

Quantum Neural Networks (QNNs): Enhancing deep learning by using quantum circuits instead of classical layers.
Quantum Kernel Methods: Using quantum computers to enhance support vector machines and other kernel-based algorithms.

Install

npm i @softquantus/softquantus-qml

Usage

import { AccessControl, Role } from "@softquantus/access";
 
/**
 * Define all your resources and their access patterns
 *
 * key => resource
 * value => array of access types
 */
type Statements = {
  user: ["read", "write", "dance"];
  team: ["read", "write"];
};
 
/**
 * Create an access control instance and pass the Statements type to enjoy full
 * type safety
 */
const ac = new AccessControl<Statements>();
 
/**
 * Now you can define one or more roles by specifying the access permissions
 *
 * This is already fully typed and typescript will let you know if you try to
 * use anything, that is not defined in the Statements type.
 */
const role = ac.newRole({
  user: ["read", "write"],
  team: ["read"],
});
 
/**
 * Simulate storing and retrieving the role in a database
 *
 * The idea here is, that you can store permissions alongside an API token.
 * Now, when you verify the token, you can also verify the access permissions.
 */
const serialized = role.toString();
 
/**
 * Note how you can pass in the Statements type again, to get full type safety
 */
const recovered = Role.fromString<Statements>(serialized);
 
/**
 * Validate the role by specifying the resource and the required access
 *
 * everything is fully typed
 */
const res = recovered.authorize({"team", ["read"]});
 
// res.success => boolean
// res.error => string | undefined provides a reason for failure
