Exact solution of a family of staggered Heisenberg chains with conclusive pretty good quantum state transfer
Pablo Serra, Alejandro Ferrón, Omar Osenda
We construct the exact solution for a family of one-half spin chains explicitly. The spin chains Hamiltonian corresponds to an isotropic Heisenberg Hamiltonian, with staggered exch…
Understanding the propagation of excitations in quantum spin chains with different kind of interactions
Alejandro Ferrón, Pablo Serra, Omar Osenda
The dynamical behaviour of the quantum state of different quantum spin chains, with designed site dependent interaction strengths, is analyzed when the initial state belongs to the…
Quantum control of a model qubit based on a multi-layered quantum dot
Alejandro Ferrón, Pablo Serra, Omar Osenda
In this work we present a model qubit whose basis states are eigenstates of a multi-layered quantum dot. We show that the proper design of the quantum dot results in qubit states t…
