Jayson Stewart shares his personal journey from JILA to ASML and what surprised him most about moving from academia into industry. The talk is intentionally light on technical details and focuses on real-world lessons and how life at JILA prepares one for a career with impact. Expect candid reflections, practical advice, and plenty of time for Q&A.
What really changes when you step outside academia? And what do you wish someone had told you before you made the leap? ASML employees will share candid stories about challenges, trade‑offs, and unexpected wins along the way. We’ll talk openly about professional shifts, visibility, mentorship, and the often-invisible skills that shape careers beyond publications and CVs. Designed as a conversation rather than a lecture, the session leaves plenty of space for questions, reflections, and real dialogue.
Join us to explore the science and engineering behind the light sources that enable advanced semiconductor manufacturing. This lecture connects industrial innovation at ASML and CLS with fundamental physics, highlighting how precision engineering, high‑power lasers, and decades of development shape modern technology.
For the overwhelming majority of organisms, effective communication and coordination are critical in the quest to survive and reproduce. A better understanding of these processes can benefit from physics, mathematics, and computer science – via the application of concepts like energetic cost, compression (minimization of bits to represent information), and detectability (high signal-to-noise-ratio). My lab's goal is to formulate and test phenomenological theories about natural signal design principles and their emergent spatiotemporal patterns.
CU Physics Prof. James Thompson explains how superheroes' understanding of fundamental physics ensures truth and thwarts villains! Sparks, explosions and plenty of action will punctuate this free STEM show that's open to students of all ages.
For over 40 years, CU Wizards presents FREE STEM Saturday morning shows for kids and their families. Visit: www.colorado.edu/cuwizards
Almost exactly 100 years ago, in the early months of 1926, Erwin Schrödinger published a series of four papers that would transform not only the prevailing theories of physics but also mankind’s very understanding of the nature of reality.
Optical lattice clocks that interrogates N atoms for an interrogation time T can, in principle, reach the quantum-projection-noise (QPN) instability σ_y (τ)∼1/(πν_0 T√Nτ), with ν_0 the clock frequency and τ the averaging time. In practice, however, dead time between preparation and readout aliases the local-oscillator (LO) frequency noise (Dick effect [1]), so the achievable instability is set by the LO noise spectrum and the duty cycle rather than by the QPN limit. This motivates zero-dead-time (ZDT) operation, which removes aliasing by maintaining continuous interrogation.
Following in the tradition of other NASA missions like Hubble and the James Webb Space Telescope, the Habitable Worlds Observatory (HWO) is a future NASA FUV-NIR flagship that will revolutionize multiple areas of astrophysics. A challenging next frontier of astronomy and planetary science is to directly image temperate Earth-sized in planets in the habitable zones of Sun-like stars, measure their spectra, and search them for signs of life. HWO will be the first observatory designed to tackle the question “Are we alone?”.
The power of quantum information lies in its capacity to be nonlocal, encoded in correlations among entangled particles. By contrast, the interactions between particles are typically local, posing both conceptual and practical challenges in understanding, generating, and harnessing entanglement. To circumvent this bottleneck, we trap an array of atom clouds in an optical resonator that mediates effectively nonlocal interactions, letting photons act as messengers that convey information between distant sites.

Abstract: Low energy collisions between molecules in the atmosphere lead to about 50% of the particles that act as the seeds for cloud droplets. Many of these molecules, and many of the other particles, are the result of human activity. Therefore cloud droplet concentrations have increased over the industrial period. The increase has led to a poorly quantified cooling effect on Earth that has offset perhaps a third of historical warming from greenhouse gases. The CLOUD experiment at CERN is a laboratory facility for the study of atmospheric particle formation.
Spin glasses are canonical examples of complex matter and form a basis for describing artificial neural networks. Repeatable control over microscopic degrees of freedom might open a new window into their structure and dynamics. I will present how we achieved this at the atomic level using a quantum-optical system comprised of ultracold gases of atoms coupled via photons resonating within multimode cavities.
Continuous-variable quantum systems enable encoding complex states in fewer modes through large-scale non-Gaussian states. Motion, as a continuous degree of freedom, underlies phenomena from Cooper pair dynamics to levitated macroscopic objects. Hence, realizing high-energy, spatially extended motional states remains key for advancing quantum sensing, simulation, and foundational tests.
In the talk, I will present the following control tasks for various nonlinear mechanical systems, including trapped atoms, levitated particles, and clamped oscillators with spin-motion coupling.
Since 2019, the CUbit Quantum Seminar Series at the University of Colorado Boulder has been a cornerstone of Colorado’s rapidly expanding quantum innovation ecosystem. Each seminar brings leading quantum scientists, entrepreneurs, and technologists from around the world to campus, creating a rare forum where students, researchers, and industry partners engage directly with the people and ideas shaping the future of quantum technology.
The Will Lab studies quantum systems of ultracold atoms and molecules. The lab cools atoms and molecules to temperatures less than a millionth of a degree above absolute zero, where atomic behavior is fully governed by quantum mechanics. Under these conditions, the lab controls individual quantum particles and their interactions with high precision using atomic physics tools, enabling novel platforms for many-body quantum physics, quantum simulation, quantum computing, and quantum optics.
I will discuss the standards of time and frequency and how these standards have evolved over the centuries. I will present the current definitions of time and frequency and how these definitions are likely to evolve in the coming years.
