Electrical Measurements of the Spin Accumulation. 
Auteur(s): Dyakonov M.
Conférence invité: III Colloque franco -russe (St. Pétersbourg, RU, 2006-09-05)
Ref HAL: hal-00289350_v1

Résumé: It is shown that the spin accumulation at the sample edges, caused by the
Spin Hall Effect should lead to a specific magnetoresistance, which could
be used for electrical measurements of the spin accumulation.

Auteur(s): Dyakonov M.
Conférence invité: V International advanced research workshop "Future trends in
microelectronics" (Crête, GR, 2006-08-09)

Résumé: Room-temperature generation of terahertz radiation in nanometer gate length InAlAs/InGaAs and AlGaN/GaN high-mobility transistors is reported. A well-defined source-drain voltage threshold for the emission exists, which depends on the gate bias. Spectral analysis of the emitted radiation is presented. The highest emission power emitted from a single device reached 0.1 µW.

Is Fault-Tolerant Quantum Computation Really Possible?

Résumé: The so-called "threshold" theorem says that, once the error rate per qubit per gate is below a certain value, indefinitely long quantum computation becomes feasible, even if all of the qubits involved are subject to relaxation processes, and all the manipulations with qubits are not exact. The purpose of this article, intended for physicists, is to outline the ideas of quantum error correction and to take a look at the proposed technical instruction for fault-tolerant quantum computation. It seems that the mathematics behind the threshold theorem is somewhat detached from the physical reality, and that some ideal elements are always present in the construction. This raises serious doubts about the possibility of large scale quantum computations, even as a matter of principle.
Commentaires: Based on a talk given at the Future Trends in Microelectronics workshop, Crete, June 2006. 8 pages, 1 figure
