Supremacía cuántica con tecnologías cuánticas

Abstract

In this work, we aim to give an introduction to quantum technologies and quantum computation, providing an overview of its foundation. Our main goal is understanding the claim done by Google in which, supossedly, quantum supremacy is achieved experimentally. Quantum supremacy is known as a quantum computation that is much faster than any computation done with current classical computers. In order to get there, a brief explanation of qubit, logic qubit gates and quantum algorithms is given, in addition to a basic introduction to superconducting circuits with which qubits are built. Finally, a short mathematical approach to ”Quantum speckle”, the algorithm used in the experimental setup of Google and a review of the already named experiment and its consequences is carried out.
