This article introduces QScratch, a novel educational tool designed to introduce fundamental quantum concepts and principles. It is an extension of the high-level block-based visual programming language Scratch, developed by the MIT Media Lab. The quantum concepts taught are presented in a simple and illustrative, yet rigorous way. The selection of...

The use of graphical language in quantum computing for the representation of algorithms, although intuitive, is not very useful for different tasks such as the description of quantum circuits in text environments, the calculation of quantum states or the optimization of quantum circuits. While classical circuits can be represented either by circuit...

Quantum computing is an emerging and quickly expanding domain that captivates scientists and engineers. Recognizing the limitations of conventional educational approaches in adequately preparing individuals for their incursion in this area, this research introduces a novel board game called “Qubit: The Game”, whose objective is twofold: 1) to foste...

This paper describes the implementation of a software module that allows the generation of quantum circuits from the definition of their classical analog logic circuits. This tool confers a great power of abstraction to the user, who does not need to know any concept of quantum computing to implement quantum algorithms or quantum protocols. Thus, t...

Key distribution allows two parties to produce and share a random secret key, which can then be used to encrypt and decrypt messages with symmetric cryptosystems. Thus, this is often considered the most fundamental cryptographic primitive of secret communications, especially in wireless networks. While the traditional method is based on the assumpt...

Quantum computing is a promising and rapidly growing interdisciplinary field that attracts researchers from science and engineering. Based on the hypothesis that traditional teaching is insufficient to prepare people for their introduction to this field, this paper presents Qubit: The Game, an innovative board game to promote both the motivation to...

This paper presents an implementation of the E91 protocol for the distribution of quantum keys, providing an intuitive class structure that represents the different existing relationships between the collaborating entities in the simulated communication. This development is included in a toolset, called QuantumSolver, developed by the authors under...

This paper introduces a new opensource quantum tool-set called QuantumSolver based on Qiskit to help developers without knowledge in quantum computing. The developed library includes a set of algorithms with different features: random number generation, Bernstein-Vazirani algorithm and quantum key distribution using the BB84 protocol. This paper de...
