Abstract: Silicon Vacancy (SiV) centers in diamond coupled to nanophotonic cavities offer a promising platform for quantum communication. Our system utilizes long coherence times, high optical cooperativities, and on-chip scalability, providing a unique path to the practical implementation of long-distance quantum networking.
Ingredients for scaling-up two different quantum systems: neutral atoms in tweezer arrays and quantum networks with spins in diamond

Abstract: Primitive asteroids (PAs) are the remaining building blocks of our Solar System (SS) study their composition, location and evolution will help us understanding how different materials travel along the Solar System and how they appeared on Earth. They are characterized by dark surfaces (albedo < 10%) dominated by carbon compounds. Their reflectance spectra are similar to those of carbonaceous chondrites (CCs), the most pristine meteorites in our records, that are abundant in hydrated minerals and organics.

Seminar Abstract:
Exploring Quantum Networking Nodes for Neutral Atom Tweezer Arrays
When
-
Abstract: Rydberg atom arrays have emerged as a promising candidate for quantum computation. However, scaling up the platform beyond a few thousand qubits would require a modular approach. An integrated optical cavity could serve as a quantum networking node between distant quantum processors. In this talk, I will show our results towards this integration for two candidate platforms: a nano-photonic crystal cavity (PCC) and a Fabry-Perot Fiber cavity (FPFC). In our lab, we have already demonstrated all the necessary quantum networking capabilities of the PCC for ground-state atoms.

Mesospheric Response to the 2022 Hunga Tonga – Hunga Ha`apai Volcanic Eruption
When
-
Abstract: On January 15, 2022, the eruption of a submarine volcano in Hunga Tonga – Hunga Ha`apai (HTHH, 20.54°S, 175.38°W) resulted in a volcanic plume that reached a height of 57 km, increasing the total stratospheric water vapor burden by 10% and forming a sulfate aerosol layer. Satellite observations in the summer of 2022 revealed the lowest tropical mesospheric temperatures and highest extratropical mesospheric temperatures observed in the past 20 years.

Computer Science Colloquium-Certified Randomness from Quantum Supremacy
When
-
Abstract: We propose an application for near-term quantum devices: namely, generating cryptographically certified random bits, to use (for example) in proof-of-stake cryptocurrencies. Our protocol repurposes the existing "quantum supremacy" experiments, based on random circuit sampling, that Google and USTC have successfully carried out starting in 2019.
