Practical QKD based on entanglement

James Grieve

The Technology Innovation Institute, Abu Dhabi, United Arab Emirates

Quantum key distribution (QKD) today is a highly developed set of technologies, with numerous demonstrations worldwide. With the promise of secure communications based on the laws of physics, it seems on-course to play an important role in our future communications infrastructure. Of the many QKD protocols in development, only a small number harness entanglement. In this talk I will discuss the advantages and disadvantages of this design decision, and argue that entanglement-based protocols can offer real advantages to practical networks

As part of a research project, a new hybrid forming process for ultrathin three-dimensional glass elements was developed. In a continuous process chain, the three-part procedure enables large-area gravity-assisted bending of thin glass, partial deep-drawing of individual structures using CO2 laser radiation and cutting of flexible contours. Using an experimental setup with a laser scanning system, novel component designs can be generated in a highly flexible and reproducible manner. This opens up new application fields or expands existing ones, for example in the area of cover glasses for display technology.

Optical fiber based Gamma radiation measurement

Bretislav Mikel1, Michal Jelinek1,2, Simon Rerucha1

1Institute of Scientific Instruments of the CAS, v. v. i., Czech Republic; 2The Faculty of Electrical Engineering and Communication, Brno University of Technology

We present our results of Gamma radiation measurement with optical fibers and crystal scintillator LYSO. The LYSO crystal detect the Gamma radiation and the optical fibers transfer output visible radiation from LYSO into single photon counter.

Quantum dot PL emission control through a nearby graphene layer

César Rui Bernardo, Peter Schellenberg, Diogo Cunha, Fatima Cerqueira, Michael Belsley, Mikhail Igorevich Vasilevskiy

Minho University, Portugal

In this work we explore the changes in the PL of CdSe colloidal quantum dots deposited on CVD graphene as the Fermi-level of graphene is varied. In solution, the QDs PL consists of a broad-band centred at λ=590 nm. This emission band becomes considerably narrower as the doping level of graphene is increased. Furthermore, the luminescence maximum shifts to the blue when switching from p-doping to n-doping of the graphene. We hypothesize that selective quenching of the emission of some QDs within the size distribution underlies these observations.

Femtosecond laser writing of integrated photonic circuits in diamond

1Istituto di Fotonica e Nanotecnologie-Consiglio Nazionale delle Ricerche (IFN-CNR) and Dipartimento di Fisica - Politecnico di Milano, Piazza Leonardo da Vinci 32, Milano 20133, Italy; 2Istituto di Fotonica e Nanotecnologie-Consiglio Nazionale delle Ricerche (IFN-CNR), Department of Science and High Technology, Università degli Studi dell’Insubria, Via Valleggio 11, 22100 Como, Italy

Integrated photonic circuits pave the way for next generation technologies for quantum information and sensing applications. Femtosecond laser writing has emerged as a valuable technique for fabricating such devices when combined with diamond’s properties and its nitrogen vacancy color center. Such color centers are fundamental for sensing applications, being possible to excite them and read them out optically through the fabrication of optical waveguides in the bulk of diamond. We show how to integrate these building blocks in diamond, to develop proof-of-concept devices with unprecedented electric and magnetic field sensitivities.
