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.
