A quantum light source is a device that can generate one single photon - or an entangled pair of photons - on demand. Whilst a single photon emitter would be pretty useless as a car headlight or bedside lamp, these devices are in increasing demand for new developments in optical communication which might exploit fundamental principles of quantum physics to achieve data security. Linear optical quantum computation, precision optical measurement and even random number generation also present potential applications opportunities for such light sources. However, many of the most mature quantum light sources operate at temperatures only accessible using liquid helium, at best inconvenient and at worst prohibitive for applications. Exploiting nitride semiconductors allows device concepts developed in the more conventional arsenide semiconductor family to be applied, but whilst arsenide devices are limited to cryogenic temperatures, nitride devices can operate at temperatures accessible using on-chip, Peltier cooling, and in some cases even at room temperature. Unfortunately, working with these less mature semiconductors has its pitfalls: high densities of defects and the impact of internal electric fields can limit device performance. For example, the wavelength of emission from nitride single photon emitters wanders with time, which is not compatible with applications which demand resonance of the emitter with a cavity or (more stringently) the emission of indistinguishable photons. Nitrides crystals grown in unusual orientations can overcome these challenges whilst maintaining good temperature stability, providing new opportunities for real-world quantum technologies.

Please join IEEE Iowa-Illinois Section and IEEE Iowa-Illinois Computer Society hosted virtual presentation and virtual dinner on Wednesday, April 20, 2022, at 5:30 pm. Cyberspace has been very much part of our well-being. For the most part, cyberspace, with its endless opportunities, has a very positive effect on people's lives. Cybersecurity deals with protection of data such as Personally Identifiable Information (PII), Protected Health Information (PHI), intellectual property, industry and government information from unauthorized disclosure and accidental destruction. With increased global connectivity, use of cloud services, and widespread deployment of Internet of Things (IoT), the risk of potentially successful cyber attacks is ever increasing. Small businesses are also at greater risk of cybercrimes. In this presentation, we review some of the significant risks faced in cyberspace as exemplified by real-life stories and provide a few viewpoints on making cybersecurity a priority for everyone. The presentation will be followed by open discussions and a virtual dinner. (IEEE membership is not required to attend the event.) Speaker(s): Dr. Binto George, Agenda: 5:30pm - 6:15pm Presentation, Q&A 6:15pm - 7:00pm Discussion/Virtual Dinner Virtual: https://events.vtools.ieee.org/m/307679
