Quantum Computing for Business (Exploring Opportunities Available Today)
Quantum Computing for Business (Exploring Opportunities Available Today)
Title: Quantum Computing for Business (Exploring Opportunities Available Today) Date: June 27 2026 Saturday Noon - 14:00 EDT Summary: Big media reports that current quantum computers are not able to attack business problems at scale. In Ron's experience, this is only about 95% true. He has found that certain types of quantum computers, specifically quantum annealers, are very good at solving constraint based optimization problems at business scale. This presentation will answer the question “What is quantum computing?” by comparing quantum computers to classical computers and describing the various types of quantum qubits. Ron 'll introduce what quantum computers can be used for and what they shouldn't be used for. Next, Ron will look at a number of quantum computing use cases that are currently available to businesses today. Finally, Ron ’ll present conclusions with a brief discussion of future hardware. There will be time for Q & A. Speaker: Ron has been fortunate to have worked in a broad range of technical disciplines during his career. Areas in which he developed expertise and innovative results include, digital hardware design, silicon functional architecture (chips), computer language compiler development, and medical software. Ron has recently immersed himself in quantum computing technologies and has obtained more than a dozen certificates across the quantum spectrum. These technologies include various hardware platforms, numerous quantum programming frameworks and quantum sensors. As a co-founder and CQTO of B2Quantum, Inc, Ron has served as a quantum computing Subject Matter Expert (SME) for a large pharma company. As a SME, he performed quantum computing use case analysis, strategic planning, budget guidance and risk analysis. Outside of the technical arena, Ron is a licensed pilot, certified open water SCUBA diver, bicyclist, wood worker and a once in a while artist.

With minimal luck and plenty of negotiation, Container offers a tense and interactive experience full of clever deals and surprising market swings. We will have multiple copies of the game.

Customize the IDE: Building Extensions for Visual Studio Code - Alan Barber
Customize the IDE: Building Extensions for Visual Studio Code - Alan Barber
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
