A paper “Qubit lattice coherence induced by electromagnetic pulses in superconducting metamaterials” published in a journal Scientific Reports that is a part of Nature group

A paper “Qubit lattice coherence induced by electromagnetic pulses in superconducting metamaterials” by researches of our laboratory Zoran Ivic, Nikolaos Lazarides and Georgios Tsironis published in a journal Scientific Reports that is a part of Nature group. The article is available in web page Publications. A superconducting quantum metamaterial comprising superconducting charge qubits loaded periodically on a superconducting transmission line has been investigated theoretically and numerically. In the paper it is demonstrated that two remarkable quantum coherent optical phenomena, i.e., self-induced transparency and Dicke-type
superradiance, may occur during light-pulse propagation in this quantum metamaterial. Also it is demonstrated that the propagating electromagnetic pulses may induce quantum coherent population inversion pulses in the metamaterial.

Our colleagues believe that the experimental confirmation of such effects in superconducting quantum metamaterials may open a new pathway to potentially powerful quantum computing.

Moscow Mini Maker Faire

The first in our country festival Maker Faire, which has already won people’s hearts all over the world, was held in NUST “MISiS” in  July, 9-10 .

In the frame of the festival Moscow Mini Maker Faire in NUST “MISiS” students working in our laboratory Nikita Volsky, Mariya Kogokar` and Ivan Stenischev with the supervisor Alexey Basharin experimentally demonstrated toroid dipole response in metamaterial based on clusters of cylindrical particles. The topology of the clusters allows us to observe the toroidal moment in a narrow range of frequencies (1-3 GHz). In their experiment they use the specially designed and created  anechoic chamber.

Great interest has been expressed by the participants of the festival in the experiment and inventions of our colleagues.

MONTH OF POSTDOCS LECTURES 2016

In the framework of MONTH OF POSTDOCS LECTURES 2016 PhD Ben Hamida Aymen and his scientific advisor Prof. Valery Ryazanov will give the lectures introducing their  joint scientific work in the laboratory for superconducting metamaterials.

Lectures will be  held on 18th of May, between 15:00 and 17:00, library.

  1. Valery V. Ryazanov: “Цифровая и квантовая сверхпроводящая электроника” (Russian language).
  2. Aymen Ben Hamida: “Ferromagnetic Josephson Junctions for superconducting cryogenic memories” (English language).

Abstract:

To realize novel elements of superconducting electronics and spintronics based on hybrid nano- and microstructures, a Josephson magnetic memory based on Josephson superconductor/ferromagnet/superconductor junction (SFS junction) is fabricated and investigated [1,2].  The first successful experiment detecting a perceptible supercurrent in an SFS structure was carried out in 1999 [3]. An application of small external magnetic field changes the magnetization of the ferromagnetic layer that in turn changes the junction critical current Ic, allowing the realization of two distinct states with high and low Ic, corresponding to logical “0” and “1” states, respectively.

In this lecture, a quick review of Josephson magnetic memories will be given as well as new results on multilayered Josephson SIsFS structures, with a tunneling barrier (I) and a thin superconducting layer (s), namely Nb-Al/AlOx-Nb-Pd0.99Fe0.01-Nb junctions.

Russia’s first superconducting qubit

Scientists from leading universities and scientific centers actually created the first in Russia superconducting qubit necessary for the quantum computer creation. A group of researchers led by Oleg Astafiev (MIPT), Alexey Ustinov  and Valery Ryazanov  worked on this project. Alexey Ustinov shared his comments on this outstanding invention.

First steps towards qubit creation were made two years ago in 2013, when researchers from the Laboratory of Superconductive Materials, NUST «МISiS» together with the Russian Quantum Center led by Alexey Ustinov measured the qubit for the first time. However, the qubit under investigation was manufactured in Germany by the group of researchers led by prof. Eugeny Iliechev whose new laboratory in currently under construction in Novosibirsk. Creation of the Russian know-how for the superconducting qubit manufacturing was quite effort consuming.

The process of qubit measuring meant its penetration by microwave radiation with a subsequent measuring of such radiation phase shift. The measurements proved that the obtained system was indeed a qubit with two fundamental states. Qubit’s principal property to acquire two-state superposition simultaneously was also demonstrated.

Creation of the superconducting qubit know-how by 2015 required more resources both human and technological hence almost every R&D center in Russia competent in the field of superconducting quantum devices participated in this scientific experiment.

Prof. Alexey Ustinov, Head of the Laboratory for Superconductive Materials, NUST «МISiS», professor at Karlsruhe Institute of Technology shared the following comments on this outstanding experiment for the Russian science:
«Now it is obvious that critical mass has accumulated in Russia, i.e. scientific centers, equipment, know-how, researchers and developments; this is the foundation for the competition with the leading world research centers including the field of quantum computer creation. No doubt, NUST «МISiS» is a prominent member of this scientific community – so far there are only four labs in Russia capable to conduct experiments involving qubits, and our research team is among the best».

According to Alexey Ustinov, «Quantum computer will allow deciphering any messages coded by modern cryptographic algorithms. Its creation will lead to vast changes in data security systems. Besides, quantum computers will allow using principally new information technology systems responsible for the data quantum processing. Quantum computing devices will provide for a broad spectrum of solutions, for instance synthesis of materials with desired properties, complex image sorting, optimization and recognition problems, and quantum system modeling as such. The majority of such problems has no solution using common classic computers».
