Steady State Entanglement in Quantum Dot Networks
... internal parameters can be tuned such that the steady state of transport through the network has a large population of the singlet state with one electron on each of the outer dots. The main ingredient for achieving the large singlet population on the outer dots is the exchange splitting between the ...

In the third chapter we give the main results of the single electron quantum dot physics and in particular how the tunneling energy is influenced by the spin-orbit interaction. In the fourth chapter the details of the role of the s ...

Quantum error-correcting codes from algebraic curves
... single- and double-error-correcting binary codes satisfy the bound given in Theorem 1.3. Nearly a decade later, it was shown for degenerate q-ary stabilizer codes of minimum distance 3 [22] and minimum distance 5 [1]. A major open problem in quantum coding theory is to determine if there is a Hammin ...

... of the diffeomorphism-invariant lattice action is hardly possible. We propose to replace the action over a manifold by a sum over the lattice cells, and to adjust the Lagrangian to a cell, rather than to a vertex. We show that in this way any diffeomorphism-invariant action involving only covariant ...

In order to have a contribution affected by a train of pulses, its originating process must be affected. This is independent of the particular decay law. The condition that justifies the multiplic ...
