- Spectroscopy with Josephson Junctions
- Time: 11:00 am
- Place: 4274 Chamberlin Hall
- Speaker: Dr. Çaglar Girit, College de France
- Abstract: Spectroscopy, by providing a direct measurement of the energy spectrum, is a powerful tool to probe matter. Conventional spectroscopy techniques suffer several drawbacks when applied to mesoscopic systems, or artificial quantum coherent atoms. I present an on-chip, Josephson-junction based spectrometer which surpasses state-of-the-art instruments, works between 2-200 GHz, and is ideally suited for probing elementary excitations in mesoscopic systems. I describe the operating principle and design of the spectrometer, show spectra of several superconducting quantum circuits, and outline experiments to investigate single quasiparticles in superconductors.

- 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.
