When Noise is the Signal: Highlights in Qubit-Based Quantum Spectral Estimation

When
-

Abstract: Accurate characterization and control of open quantum systems exposed to realistic, spatio-temporally correlated noise are vital for exploiting the full potential of quantum technologies. Thanks to their exquisite sensitivity to the surrounding environment, qubits can be naturally considered as “spectrometers”, or sensors, of their own noise.

Forces on Everything Everywhere All at Once

When
-

Abstract: In order to perform some of their most important functions, cells must be able to generate, sense, and respond to mechanical forces. Many mechanosensing proteins have been discovered that are believed to change their behavior in a predictable and repeatable way when they are under mechanical tension. Yet, in most of these cases, we don't know the molecular details of how this force shifts the conformations adopted by the protein, or how this then leads to a concomitant change in function.

We are excited to announce the first CU Phonon Club seminar of the semester. Please join us for a great talk, interesting discussion, and FREE FOOD. We are pleased to feature Dr. Ravid Shaniv from Prof. Regal's group who will be presenting their recent work. Also, we are planning on hosting two more talks this semester. Feel free to pass this email along to any others who may be interested. We hope to see you on Wednesday!

The New Age of Exploration and Science at the Poles of the Moon

When
-

Abstract: More than one hundred years ago, exploration of the Earth's polar regions reached a fever pitch. Competition for the South Pole ultimately led to scientific discoveries whose legacy persists to the present day. Similarly, the poles of the Moon have become a new frontier for science and exploration. Perennial shadows in near-polar craters -- many of them named for famous Antarctic explorers -- remain cold enough, < 100 K, to trap water and other volatiles for billions of years. Where might these volatiles come from?

Vibrational Spectral Signatures and Ultrafast Dynamics of Strong H-bonds Investigated with Cryogenic Ion and 2D IR Spectroscopies

When
-

Abstract: H-bonding interactions and proton transfer processes play central roles throughout chemistry and biology. Spectroscopic studies that directly probe strong H-bonds and proton transfer reactions, however, remain a formidable experimental challenge. We aim to characterize vibrational spectral signatures and dynamics of strong H-bonds by complementing high-resolution gas-phase techniques (cryogenic ion spectroscopy) with ultrafast time-resolved solution-phase experiments (transient absorption, 2D IR).
