Thesis Defense
Generating entangling gates in superconducting quantum circuit
Time: 2:00 pm - 4:00 pm
Place: 5310 Chamberlin Hall
Speaker: Yinqi Chen, Physics PhD Graduate Student
Abstract: Qubit entanglement is a crucial step toward a universal quantum computer. A qubit system based on superconducting circuit has the advantage that it is easy to achieve relatively strong coupling between qubits, therefore fast entanglement is possible. This thesis focuses on the method to manipulate fast entanglement in a superconducting quantum circuit, in particular on the method to realize fast entangling two-qubit gate. The first half of the thesis presents the result of fast high-fidelity two-qubit gate on fluxonium qubits, specifically the sqrt-iSWAP gate and the cross-resonant CNOT gate. The second half of the thesis starts with a general investigation on the parametric quantum state transfer between two quantum resonators, then presents an application of parametric transfer to the gatemon qubit system. The result demonstrates that parametric resonance enables fast and high-fidelity iSWAP, CNOT, and sqrt-iSWAP gate on gatemon qubits.

Summer Recess
Time: 12:30 pm - 1:00 pm
Place: Bascom Hill outside Birge
Speaker: Sharon Kahn
Abstract: Come take a break and play from 12:30-1 on Bascom Hill (outside of Birge)! Some of us will be walking up, leaving from the courtyard between Chamberlin and Sterling ~12:25 – feel free to walk with us!

Cornhole, ladder toss, frisbee, juice boxes. . . .
Hope you’ll join us!

Graduate Program Event
Black and Brown in Physics info meeting
Time: 2:00 pm - 3:00 pm
Place: B343 Sterling or
Abstract: Ayshea Banes, 2nd year PhD student, will host an informational meeting on August 7th at 2pm in room 2314 in Chamberlin. This will be a fairly short and simple meeting consisting of seeing the amount of people interested in this org and providing a basis of what this org will be about. This meeting (and org) is open to anyone who identifies as black and/or brown, and anyone who considers themselves an ally to the black and brown community!

I am excited to finally put this in action and I hope to see a bunch of you there!

Outreach
Madison Astronomical Society meeting featuring Justin Vandenbroucke
Time: 7:15 pm - 9:00 pm
Place: online and UW Space Place
Speaker: Justin Vandenbroucke, Physics, WIPAC
Abstract: At the August 9, 2024 meeting of the Madison Astronomical Society, Justin Vandenbroucke, UW Madison Associate professor of physics, will give a talk titled:
Astronomy with the highest energy light in the Universe
Major breakthroughs have been made in astronomy by expanding observations to far longer and far shorter wavelengths than we can see with our eyes. The shortest-wavelength photons are gamma rays, the highest energy photons in the Universe. Some of these photons are trillions of times more energetic than the human eye can detect. There is a surprising variety of astronomical sources glowing or flashing in these very-high-energy gamma rays. They are powered by some of the most extreme objects in the Universe: exploding stars, white dwarfs, neutron stars, and black holes. I will describe the science that very-high-energy gamma rays enable and the prospects for the Cherenkov Telescope Array Observatory, an international project currently under construction.
Justin Vandenbroucke is an associate professor at the University of Wisconsin–Madison, in the Physics Department and Wisconsin IceCube Particle Astrophysics Center. His research focuses on gamma-ray astronomy with the Cherenkov Telescope Array Observatory, neutrino astronomy with the IceCube Neutrino Observatory, and citizen science with the Distributed Electronic Cosmic-Ray Observatory. Vandenbroucke obtained his PhD in Physics from UC-Berkeley and held postdoctoral positions as a Kavli Fellow at Stanford University and NASA Einstein Fellow at SLAC National Accelerator Laboratory. Vandenbroucke is currently a UW–Madison Vilas Associate.
This meeting will take place in person at our usual Space Place classroom location. It will also be streamed live to our YouTube channel at
