A single-electron double quantum dot with Rashba spin-orbit interaction as a working substance for heat machines
Ivan Romualdo de Oliveira, Vinícius N. A. Lula-Rocha, Moises Rojas
We investigate the thermodynamic performance of a quantum Otto machine whose working substance is a single electron confined in a double quantum dot under an external magnetic fiel…
Non-unitary extension of Grover's search algorithm
V. N. A. Lula-Rocha, M. A. S. Trindade
We have developed a non-unitary extension of Grover's search algorithm by changing the hidden geometry of Hilbert space carried by diffusion operator. Our algorithm finds the solut…
Quantum classification and search algorithms using spinorial representations
Lauro Mascarenhas, Vinicius N. A. Lula-Rocha, Marco A. S. Trindade
We propose an algebraic formulation for two distinct quantum algorithms: a quantum classification algorithm and a quantum search algorithm with a non-uniform initial distribution,…
Negativity of the Wigner function and thermal effects of Bell-Cat states
Vinícius N. A. Lula-Rocha, Sergio Floquet, Marco A. S. Trindade +2
We applied the Thermofield Dynamics formalism to analyze how the non-classical properties of the Bell-Cat states are influenced by a gradual change of temperature values, in a ther…
