AB This end of degree project constitutes an introduction to Quantum Computation. It presents a combination of theoretical concepts, mainly based in theguidelines of “Quantum Computation and Quantum Information” of MichaelA. Nielsen & Isaac L. Chuang [NC02], and the implementation of some ofthem at IBM’s online quantum computers [ibm18]. The aim is therefore torealize a first approach to some basic concepts of Quantum Computation andQuantum Information and put them in practice. Particularly, after the introduction of qubits and essential ideas about entanglement and multiple qubitstates, the 14-qubit quantum computer IBM Q Melbourne was employed togenerate both Bell and GHZ states. After that, a quantum/classical hybridalgorithm known as Variational Quantum Eigensolver (VQE) [Com16] wasintroduced as a crucial tool for the next two targets of the project. The firstof them consists on exhaustively analyzing and solving an optimization problem named Exact cover problem [Gal17]. The second one relates to find theground state of a bidimensional Ising model and study the evolution of bipartite entanglement, as measured by the von Neumann entropy, in the approachof the system to its ground state.
