Quantum Science Perspectives
11 May, 17:00
The Hebrew University/Edmond J. Safra,
Givat Ram, Jerusalem


The Hebrew University's Quantum Information Science Center invites you to explore the breadth and depth of quantum science, through a series of lectures by world leaders in the  fields  of  quantum  computational  complexity,  physical  realizations  of  quantum processors, verifiability of quantum dynamics, and more. This  series  aims at  bringing  together  the  broad community of  quantum  researchers  in Israel, spanning physics, computer science, math, chemistry and engineering. The talks will be held approximately once a month.

  • To get email announcements on the lectures in this series, please add your email to the mailing-list in the link below.

  • If you intend to arrive by car, please notify us through the form at the bottom of the page with your car details, so that you'll have an entry permit ready.

Quantum Technologies with Atomically Thin Materials

Engineering robust solid-state quantum systems is amongst the most pressing challenges to realize scalable quantum photonic circuitry. While several 3D systems (such as diamond or gallium arsenid) have been thoroughly studied, solid state emitters in two dimensional (2D) materials are still in their infancy.

In this presentation I will discuss the appeal of an emerging van der Waals crystal – hexagonal boron nitride (hBN). This unique system possesses a large bandgap of ~ 6 eV and can host single defects that can act as ultra-bright quantum light sources. In addition, some of these defects exhibit spin dependent fluorescence that can be initialised and coherently manipulated. In this presentation I will discuss in details various methodologies to engineer these defects and show their peculiar properties. Furthermore, I will discuss how hBN crystals can be carefully sculpted into nanoscale photonic resonators to confine and guide light at the nanoscale. Taking advantage of the unique 2D nature of hBN, I will also show promising avenues to integrate hBN emitters with silicon nitride photonic crystal cavities.

All in all, hBN possesses all the vital constituents to become the leading platform for integrated quantum photonics. To this extent, I will highlight the challenges and opportunities in engineering hBN quantum photonic devices and will frame it more broadly in the growing interest with 2D materials nanophotonics.
