Some expert speaker (or panel) will be telling us about some subject, or maybe we'll hold a roundtable discussion, or whatever. Please bring your questions, ideas, etc., and a friend or three who might be interested in our Meetup. Approximate Schedule: 7:00 pm: people arrive, network, mingle, and eat pizza 7:30 pm: presentation, discussion, or whatever, begins 8:30 pm: presentation/whatever is over; we network, mingle, and clean up 9:00 pm: we lose the room There has been progress on finding a space sponsor and a dinner sponsor, but nothing is yet set in stone. Meanwhile, I will hold the meetings at the Fairfax City Regional Library, bring pizza and soft drinks, and put out a donation jar. (When you RSVP, you can tell me what you want. There's no guarantee you'll get it, and "nothing" is a perfectly good answer.) PLEASE RSVP YES IF COMING, AND CHANGE IT TO "NO" IF YOU THEN WON'T COME AFTER ALL. DO NOT MAKE US WASTE TIME WAITING FOR YOU. DO NOT DEPRIVE OTHERS OF A SPACE BY BOGARTING ONE. DO NOT MAKE ME THINK UP AN APPROPRIATE PENALTY FOR NO-SHOWS. DO NOT ATTEMPT TO ADJUST THE PICTURE. DO NOT TAUNT HAPPY FUN MEETUP ORGANIZER. This will be a joint meeting with the Independent Consultants of NoVa, DC, and MD (https://www.meetup.com/Independent-Consultants-of-NOVA-DC-MD).

Want to mess with some electronics? Or perhaps contribute to HacDC's main group project? HacDC's latest event brings hardware projects to the community. We will focus primarily on the main project (Space Blimp!) but please feel free to bring some of your own projects to show off and work on!

Title : Design of a Quantum Photonic Full Adder Gate based on an 8-mode Integrated Optical Circuit Date: Feb 28 2026 Noon - 14:00 EST Abstract: Multiport interferometers designed using the Clements decomposition algorithm can be used to implement compact quantum-photonic full-adder (FA) gates on photonic integrated circuits (PICs). By expressing each element of the FA gate matrix in terms of the permanent of a non-unitary matrix, enabled through Boson sampling, the required number of MZIs in the gate can be further reduced. In this presentation, we will discuss the design of an FA gate modeled as a four-photon scattering process on an eight-mode integrated optical circuit, where the permanents of submatrices determine the output probabilities. Simulation results demonstrate a fidelity of 1 and a success probability of 2.22 × 10⁻⁴ for the FA gate. We will also examine the impact of phase-shifter and attenuator variations on fidelity and success probability using Ansys Q-Interconnect software. Finally, we will compare the performance of the proposed FA gate with a benchmark Toffoli gate designed using the same approach. Speaker: Shafiqul Hai received the B.Sc. degree in Electrical and Electronic Engineering from the Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 2007, and the M.Eng. (Thesis) and Ph.D. degrees in Electrical Engineering from McGill University, Montreal, QC, Canada, in 2011 and 2016, respectively. He is currently an Assistant Professor in the Department of Electrical and Computer Engineering at Lakehead University. His research interests include the modeling and characterization of compact nanophotonic devices and components for next-generation optical fiber and RF communication systems, as well as quantum computing on photonic integrated circuits. He is the author or coauthor of more than 12 peer-reviewed journal papers and 15 conference publications. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation ([https://www.qaif.org/](https://www.qaif.org/)) , Dr. Sebastian Zajac , member of QPoland ([https://qworld.net/qpoland/](https://qworld.net/qpoland/)) This is an online event. Zoom registration form will be emailed to registrant and posted on the event forum by Feb 28 2026 11:00 am EST.

Hey Poetry Lovers! This group is on a roll. Here’s the gist: We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week. For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form). Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

This event is for women only. We will meet for coffee and a bite to eat at a local cafe.

Join the inaugural meeting of the Columbus Vintage Computing Club (CVCC)! Get to know others in the vintage computing space and get hands on time with a Commodore VIC-20 and various Palm Pilot PDAs! We will use this time to get to know each other, share projects we've been working on and plan the future of the CVCC. We'll be at the Hilliard Library in Meeting Room 2A at 6:00 PM - 8:00 PM

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
