Events During the Week of December 7th through December 14th, 2025
Monday, December 8th, 2025
- Plasma Physics (Physics/ECE/NE 922) Seminar
- Title to be announced
- Time: 12:00 pm - 1:00 pm
- Place: 2241 Chamberlin Hall
- Speaker: Jason TenBarge, Princeton University
- Host: Cary Forest
- Theory Seminar (High Energy/Cosmology)
- Primordial Black Holes as Dark Sector Factories
- Time: 1:00 pm - 2:30 pm
- Place: Chamberlin 5280
- Speaker: Jae Hyeok Chang, Fermilab
- Abstract: The Hawking radiation of photons from primordial black holes can be detected in future gamma-ray telescopes if PBHs constitute even a small fraction of dark matter. PBHs can likewise radiate new particles, which is particularly interesting when these particles are largely secluded from the Standard Model sector and would otherwise be difficult to access. In this talk, I will describe how such dark sector particles can be probed through the spectrum of Hawking radiation.
- Host: Joshua Foster

- R. G. Herb Condensed Matter Seminar
- Quantum computational enhanced optical imaging
- Time: 10:00 am - 6:00 pm
- Place: 5310 Chamberlin
- Speaker: Johannes Borregaard, Harvard
- Abstract: High-resolution optical imaging underpins applications from exoplanet detection and satellite monitoring to molecular imaging. Classical methods rely on tomographic reconstruction and post-processing to remove background noise, which comes with prohibitive measurement overhead and stability requirements for weak sources. In this talk, I will introduce a fundamentally different approach that replaces tomographic analysis with direct quantum processing of photonic information. Building on recent demonstrations of coherent photon-to-qubit transduction (arXiv:2509.09464), asynchronously arriving photons can be stored in quantum memories and interfered through quantum algorithms to remove background noise without tomographic reconstruction. Applied to exoplanet imaging, our estimates show several-orders-of-magnitude improvement under realistic conditions using quantum circuits of only hundreds of gates and tens of qubits. The approach generalizes to other tasks such as molecular imaging, satellite monitoring, and adaptive optics, opening new opportunities for quantum-enhanced imaging with near term quantum computers.
