Events at Physics
Events on Thursday, October 10th, 2019
- R. G. Herb Condensed Matter Seminar
- Quantum computing with superconducting circuits
- Time: 11:00 am
- Place: 5310 Chamberlin
- Speaker: Yu Chen , Google
- Abstract: In this talk, I will review the recent progress in Google AI quantum team. I will discuss the development of our flagship processor based on superconducting qubits both with fixed and tunable coupling. I will demonstrate that the tunable coupling provides us great flexibility in developing two-qubit gates for error-corrections and near-term applications. I will show we have developed technologies that enables us to achieve high performance at a system level.

- PGSC Professional Development Seminar
- Where Physics Ph.D.'s Work and How to Get There
- Time: 2:30 pm
- Place: 5310 Chamberlin Hall
- Speaker: Rob Morgan, Physics PhD Graduate Student
- Abstract: We will take a data-driven look at the job landscape for graduating physics Ph.D.s. The talk will discuss positions in academia, at national laboratories, and in the private sector. We will also discuss the typical skill set and track record of people in those positions. Visit for more information.
- Host: Rob Morgan, graduate student
- Astronomy Colloquium
- “Milky Way Science with the Dark Energy Survey”
- Time: 3:30 pm
- Place: 4421 Sterling Hall, Coffee and cookies 3:30 PM, Talk begins 3:45 PM
- Speaker: Keith Bechtol, UW Madison Physics Department
- Abstract: The stellar halo of the Milky Way represents only ~1% of the total stellar mass of our Galaxy, but is rich with clues regarding the formation history of the Milky Way, the properties of the first stars and galaxies, and the local distribution of dark matter. The current generation of wide-field optical/NIR imaging surveys including SDSS, DES, Pan-STARRS, Gaia, and HSC-SSP has allowed us to catalog more than a billion individually resolved stars out to the Milky Way viral radius and beyond with precise multiband photometry, proper motions, and light curves for variable stars. These datasets, in combination with follow-up spectroscopy, provide new perspectives on the dynamical and chemical history of the Milky Way and its satellites, and ever more stringent constraints on the fundamental nature of dark matter. I will discuss these topics, with a focus on recent results from the Dark Energy Survey (DES), a 5000 square degree imaging survey of the south Galactic cap to ~24th magnitude in the grizY bands.
