Dynamical matrix for arbitrary quadratic fermionic bath Hamiltonians and non-Markovian dynamics of one and two qubits in an Ising model environment
Fernando Iemini, Leonardo da Silva Souza, Tiago Debarba +3
We obtain the analytical expression for the Kraus decomposition of the quantum map of an environment modeled by an arbitrary quadratic fermionic Hamiltonian acting on one or two qu…
Entanglement of indistinguishable particles as a probe for quantum phase transitions in the extended Hubbard model
Fernando Iemini, Thiago O. Maciel, Reinaldo O. Vianna
We investigate the quantum phase transitions of the extended Hubbard model at half-filling with periodic boundary conditions employing the entanglement of particles, as opposed to…
Quantum process tomography with informational incomplete data of two -coupled heterogeneous spins relaxation in a time window much greater than
Thiago O. Maciel, Reinaldo O. Vianna, Roberto S. Sarthour +1
We reconstruct the time dependent quantum map corresponding to the relaxation process of a two-spin system in liquid-state NMR at room temperature. By means of quantum tomography t…
