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.
