SIG Computing Topic:  Beginner’s Guide to Understanding Binary Logic & Encryption.

Presented by  Jeff Pynnonen

We will first discuss simple binary logic (Boolean Logic). AND, OR, NOT. And move onto to SHIFTing, and the XOR(eXculsive OR)The Exclusive OR, XOR, is the basis of encryption. It basically flips or not flips bits in a message. I will show that with a key you can completely encrypt and decrypt messages (texts, data, and information).

Jeff is an engineer, with  a BSEE from the University of Michigan, primarily involved circuit design and programming. He is experienced in C, C++, Visual Basic, Fortran, assembly language, and other languages.
Today, he likes Python and wants to learn Rust. He has worked doing data analysis for automotive customer experiences, developed a Computer Aided Phone Survey Interviewing Language (CAPSIL), allowing easy design of a survey, and easy to back up to correct wrong responses. He has also worked in programming in assembler code, C, C++ and other languages for automotive modules, like engine control, brake software, emission software, diagnostics, radio and entertainment systems.

SIG Computing:

Aug 10, 2025: Quantum Computing Architectures: Feynman’s “Wonderful Problem”

 In the 1980s, Richard Feynman articulated that any computer hoping to properly simulate nature would have to be quantum mechanical, since nature is not classical. Over 40 years later, we are still trying to solve this, as Feynman described it, “wonderful problem.” In this talk, I will describe the capabilities a quantum computer can enable in technology and scientific discovery and why it is fundamentally different from classical computing. I will also discuss the strengths and weaknesses of the many quantum computing architectures all vying to achieve the ultimate goal of fault-tolerant quantum computing. 

Alex Burgers received his PhD in Physics from the University of Michigan and worked as a postdoc at Caltech and Princeton. Alex became an Assistant Professor in the Electrical and Computer Engineering department at the University of Michigan in fall 2022. His work focuses on building quantum technologies using neutral atoms. He has research grants funded by the Army, Air Force, and DARPA, and has received the NSF CAREER Award.
