Title:　New Frontiers in Characterizing Exoplanet Atmospheres

Speaker: Dr. Shang-Min Tsai, Assistant Research Fellow

Affiliation: Institute of Astronomy and Astrophysics, Academia Sinica

Place: Science Building III SC157

Abstract:

Exoplanet science has made remarkable progress. With advancements in high-resolution spectroscopy and the launch of JWST, the field has transitioned from detection to detailed atmospheric characterization.
The diversity of exoplanets presents intriguing puzzles that challenge our theoretical understanding.
In this talk, I will review progress in exoplanet research, with an emphasis on atmospheric characterization. I will highlight some recent JWST observations, including the first evidence of photochemistry on an exoplanet. I will present the enigmatic nature of intermediate-sized planets and share insights from our recent study on temperate sub-Neptunes. I will conclude with key open questions in exoplanet characterization that are within reach of upcoming capabilities.

Title:　Device-Independent Quantum Rigidity for Secure Global Positioning

Speaker: Prof. En-Jui Kuo

Affiliation: Department of Electrophysics, National Yang Ming Chiao Tung University

Place: Science Building III SC157

Abstract:

Device-independent (DI) protocols provide the strongest form of security by removing trust assumptions on quantum devices and relying solely on observed nonlocal correlations and quantum rigidity. In this talk, I will discuss how multipartite Bell nonlocality and self-testing can be leveraged to secure distributed positioning tasks, using a quantum-secured global positioning system (GPS) as a concrete case study.

We consider a protocol based on a five-qubit entangled state shared among four satellites and one ground station, where correct state preparation and measurement behavior are certified solely from Bell inequality violations. I will explain how rigidity guarantees enable device-independent authentication against spoofing and cyberattacks, and discuss practical considerations in the NISQ era, including implementation trade-offs between superconducting and trapped-ion platforms, as well as constraints arising from long-distance photonic distribution.

The emphasis of the talk will be on conveying the core ideas of device-independence and self-testing, with sufficient background to make the discussion accessible to a broad quantum information audience.
