Floquet theory of Cooper pair pumping
Angelo Russomanno, Stefano Pugnetti, Valentina Brosco +1
In this work we derive a general formula for the charge pumped in a superconducting nanocircuit. Our expression generalizes previous results in several ways, it is applicable both…
Manipulation of electron orbitals in hard-wall InAs/InP nanowire quantum dots
Stefano Roddaro, Andrea Pescaglini, Daniele Ercolani +2
We present a novel technique for the manipulation of the energy spectrum of hard-wall InAs/InP nanowire quantum dots. By using two local gate electrodes, we induce a strong electri…
Entanglement in finite spin rings with noncollinear Ising interaction
F. Troiani
We investigate the entanglement properties of finite spin rings, with noncollinear Ising interaction between nearest neighbours. The orientations of the Ising axes are determined e…
Spin Drag in Ultracold Fermi Mixtures with Repulsive Interactions
R. A. Duine, Marco Polini, Arnaud Raoux +2
We calculate the spin-drag relaxation rate for a two-component ultracold atomic Fermi gas with positive scattering length between the two spin components. In one dimension we find…
Shor's quantum algorithm using electrons in semiconductor nanostructures
Fabrizio Buscemi
Shor's factoring algorithm illustrates the potential power of quantum computation. Here we present and numerically investigate a proposal for a compiled version of such an algorith…
Achieving the Holevo bound via sequential measurements
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We present a new decoding procedure to transmit classical information in a quantum channel which, saturating asymptotically the Holevo bound, achieves the optimal rate of the commu…
