Vendredi 14 septembre

• Nanophotonics and Electromagnetism group seminar given by Luis Martin-Moreno from Université de Zaragoza at 10:30 in room N2.1 : "Electromagnetic modes confined to graphene structures: waveguides, nanoemitters and solitons".

Abstract:
Graphene has made the headlines due to its remarkable mechanic and electronic material properties. No less interesting, although up to now much less studied, are its electromagnetic properties. Notably, graphene despite being just one atom thick can bind electromagnetic modes (graphene plasmons), which has the potential for being electrically controllable by external gates.
In this talk
(i) I will analyze the properties of bound electromagnetic modes in graphene, in different geometrical configurations and different spectral ranges
(ii) analyse the radiation patterns of nanoemitters placed on the graphene sheet and
(iii) briefly discuss the existence laterally confined solitons in the
optical regime.

• Jianji Yang, PhD in Nanophotonics and Electromagnetism group, will present his work on "Theoretical Studies of Optical Fishnet Metamaterials" at 14:00 in the auditorium.

Abstract: As a composite electromagnetic material, fishnet metamaterials can provide (amazingly!!) negative-valued refractive index with relative low loss at optical frequencies. Thus it has been intensively studied in recent years. In particular, we formulated a semi-analytical model for the refractive index of this metamaterial. Theoretical studies are also performed from other aspects.

OpSciTech Opening Lectures - 2012

• Claude BOCCARA, Institut Langevin ESPCI-ParisTech/CNRS : "Imaging through scattering media: why? how? Difficulties and perspectives".
  We will briefly summarize the main approaches (Optical Coherence Tomography, Diffuse Tomography, photo-acoustics, etc.) that are used to image through scattering media and discuss their limits in term of resolution, depth and signal to noise ratio.
  Then we will point a few results that have been obtained these last years in term of wavefront control in the space domain or in the time domain.

OpSciTech Opening Lectures - 2012

• Philippe Grangier, physicist and senior researcher in quantum information at the Charles Fabry Laboratory at the Institut d’Optique Graduate School : "From single and entangled photons to quantum information".
  We will review some basic principles of quantum physics (linear superpositions, entanglement) by using photons as an illustrative example, and we will show how these principles can be used for applications in quantum information processing and communications.

Monday September 3 at 11:00

Séminaire du groupe SCOp, donné par Jun Tanida, professeur à l'université d'Osaka.

"Nano-scale Information Systems Based on Photonic DNA Nano-technology" Nano-scale information systems are expected to be useful to capture the signal in biological systems and to control the target object effectively. Photonic DNA nano-technology is one of the promising approaches for the implementation. As examples of the application, form control of DNA complexes, photonic manipulation of micro droplets, logic operations on a DNA scaffold are presented.

Noriaki Horiuchi, editor in Nature Photonique will present a seminar on "Science policy of his newspaper".

Friday July 6

• Anaïs Dréau from LPQM Cachan will present a seminar on "Single-shot readout of single nuclear spins in diamond under ambient conditions" at 11h, room S2.11

Owing to its outstanding optical and electron-spin properties, the negatively charged nitrogen-vacancy (NV) color center in diamond has recently emerged as a promising candidate for a broad range of applications including quantum information processing (QIP), photonic devices, hybrid quantum systems, nanoscale magnetometry, and imaging in life science. For QIP applications, coherent interactions of the NV defect with nearby nuclear spins of the diamond lattice provide a fertile resource for the realization of universal quantum gates, quantum registers, and multipartite entangled states.
However, in most of these experiments, the spin states were measured through multiple detection repetitions which destroy the quantum states, whereas single shot readout of qubit states are required for performing quantum algorithms, such as quantum error correction protocols.
In this seminar, we will present a three-spin system in which two nuclear spins in interaction with a single NV center can be read in single shot. The high fidelity (> 90%) of this measurement could allow for implementing active quantum feedback and testing Bell's inequality while getting free from the detection loophole.
