Fundamental elementary particle physics allows pointlike electric charges, such as electrons, and pointlike magnetic charges, sometimes referred to as magnetic monopoles, to exist in our universe.

Why should we be motivated to effect change? What can we do?

Photons are excellent carriers of quantum information over long distances and can be reliably processed in advanced photonic integrated circuits. One fundamental challenge has been that they are complex to generate, i.e. single-photon sources tend to be inherently inefficient. Solid-state quantum emitters deterministically coupled to nanophotonic circuits have overcome this challenge, and today highly efficient and coherent photon-emitter interfaces are realized, enabling generation of high-quality single-photon sources, multi-photon entanglement sources or photonic quantum gates. In this webinar we will explain the fundamental operational principle of this novel light-matter interfaces and discuss future application areas within quantum computing and quantum networks.

Optically active color centers in the solid state are leading candidates for quantum information processing due to long spin coherence times, and high-quality spin-photon interfaces, but traditional platforms based on diamond and silicon-carbide suffer from manufacturability and optical interfacing limitations. Color centers in Silicon are emerging qubit candidates operating at telecom wavelength. Platforms based on silicon color centers can leverage the mature toolbox of large-scale silicon photonics and thousands of miles of deployed optical fiber. The webinar will discuss fabrication and properties of silicon color centers, integration into photonic devices as well as technologies necessary to detect the low light level spectral emission required for their spectral characterization.

After the demonstration of the laser in 1960, researchers quickly discovered that tightly focused laser pulses generated a bright spark of ionized air. The physics of this process-- a laser-driven exponential growth of charge-- was well-understood by the end of the 1960s. An obvious potential application was extreme sensitivity charge detection in gases through the amplification of individual free electrons, in analogy to the detection of single photons or electrons by multiplier tubes. However, various technical and physics limitations delayed this application until very recently.

In this presentation I will describe the avalanche process and discuss how we overcame these limitations to develop an ultrasensitive charge detection diagnostic.

Most colored materials owe their color to the absorption of light. In nature we often see a different type of coloration, known as structural color: certain wavelengths are transmitted, while others scatter and constructively interfere. Structural colors are common in birds and particularly in blue feathers, which consist of disordered arrays of pores that scatter light.

Whirlwinds caused by thermal updrafts can pick up dust and become visible, forming 'dust devils'. Largely a harmless curiosity in desert meteorology, they can cause occasional damage.

This webinar explores jugglers' dependence on muscle memory and dynamical prediction. If every throw is considered to be an independent event, there exist juggling patterns in which the reaction time required to make successive catches and the precision needed to make perfect throws exceeds human capabilities. Using simulations with Gaussian deviations applied to throw angles and velocities, we reinforce this claim and compare the stability of various juggling patterns known as siteswaps. We show that throw angles and velocities affect very distinct aspects of juggling performance, and we obtain criteria on each that are needed to avoid juggling failures.
