String theory offers a viable theory of quantum gravity, with spin 2 gravitons encoded in closed strings.  But the failure to find evidence for supersymmetry at the LHC has left string theory in an uncertain state.  A solution to the problem is in plain sight: revert to classic nonsupersymmetric, bosonic string theory, reenvisaged as a theory of all the forces, not just the strong force.  The classic theory correctly reproduces the Brauer-Weyl (1935) algebraic relation between fermions and bosons seen in the standard model, whereas supersymmetry does not.

This is the inaugural W. Carl Lineberger Seminar which is designed to advance graduate student-organized seminars within the Physical Chemistry Program of the Department of Chemistry at the University of Colorado Boulder. The seminars address current topics in physical chemistry, promote rigorous scholarly discussion, and foster collaboration among graduate students, faculty, and invited speakers. This seminar program is supported by private donations to the University of Colorado Foundation.

Abstract: In recent years, neutral atom tweezer arrays have emerged as a promising platform for quantum computing. Among various atomic species, alkaline-earth(-like) atoms—particularly ytterbium—offer unique advantages arising from their rich internal structure. In this talk, I will present progress from my PhD work, demonstrating how these features can be harnessed to build a useful quantum computer in the future.

RASEI is hosting Prof. Richard Friend, from the University of Cambridge, UK, will be presenting on Wednesday November 12, 2025 as part of the Nozik Lecture Series from 3:00 – 4:00 PM, with a poster reception with refreshments following the talk. The talk will be on the fourth floor of the CASE building on main campus.

Edwards Vacuum will be providing a training on Ultra-high Vacuum (UHV) best practices, including best known methods on pump configuration, bake-out, etc.  The goal is to help align UHV best practices department wide to reduce experiment set-up time and re-work. This could also apply to those that do not use UHV today, but may like to take advantage of broadening their UHV knowledge for the future.

Please join us for a JAGS Industry Spotlight Seminar featuring Micron. A networking session with the speaker will take place at 12:30pm followed by a technical presentation about the ongoing projects. 

Oxford Ionics develops trapped-ion quantum computers.  We are UK headquartered and opened our US office in Boulder last year.  We will present the work we do in Boulder developing our architecture and our future plans to open a lab and  grow the team here.  We will also discuss our recent acquisition by IonQ and what it means for the companies' joint roadmap.
