POSTPONED - please check back for new date: OMQ Seminar: Stabilizing a Diamond NV center via feedback control

  • Speaker: Shuhao Wu
  • Event Type: Seminar
  • Date and Time: 11/15/2021 3:00 pm - 11/15/2021 4:00 pm
  • Location: Willamette 240D and Zoom

Decoherence caused by environmental noise is a major obstacle to developing a quantum computer.  We have developed a scheme, which is based on the phenomenon of coherent population trapping (CPT), to sense the spin bath noise surr… Read More

OMQ Seminar: Real-Time Magnetometry Using Dark States of a Nitrogen Vacancy Center

  • Speaker: Ethan Turner
  • Event Type: Seminar
  • Date and Time: 11/01/2021 3:00 pm - 11/01/2021 4:00 pm
  • Location: Willamette 240D and Zoom

We demonstrate real-time magnetometry by detecting single-photon emissions from a nitrogen vacancy center prepared in the setting of coherent population trapping and by estimating magnetic field from the time series of photon counts, which are correlated… Read More

OMQ Seminar: Interaction-free measurements with electrons

  • Speaker: Amy Turner
  • Event Type: Seminar
  • Date and Time: 10/18/2021 3:00 pm - 10/18/2021 4:00 pm
  • Location: Willamette 240D and Zoom

In transmission electron microscopy, high-energy electrons damage beam-sensitive materials while imaging, which inhibits studying proteomics and cellular dynamics at the atomic scale. To avoid sample damage while maintaining resolution, the electron dose… Read More

Metastable Qubits in Multi-Ion Systems

  • Speaker: David T.C. Allcock
  • Event Type: Seminar
  • Date and Time: 05/17/2021 4:00 pm - 05/18/2021 4:45 pm
  • Location: Zoom

While all of the basic primitives required for universal quantum computing (QC) have been demonstrated in trapped-ion qubits with high fidelity, it is currently not possible to simultaneously realize the highest achieved fidelities in a single ion sp… Read More

Studies of the local conformations and conformational dynamics of cyanine labeled DNA constructs by photon correlation fluorescence spectroscopy

  • Speaker: Andrew H. Marcus
  • Event Type: Seminar
  • Date and Time: 05/03/2021 4:00 pm - 05/04/2021 4:45 pm
  • Location: Zoom

Thermal fluctuations of DNA play an important role in the regulation of DNA replication, recombination and repair, which depends on the ability of protein machinery to recognize and to bind to selected conformations of DNA lattices. Obtaining information… Read More

How fissors works. Three-pulse femtosecond stimulated Raman spectroscopy as a probe of conformational motion

  • Speaker: Jeff Cina
  • Event Type: Seminar
  • Date and Time: 02/15/2021 4:00 pm - 02/16/2021 4:45 pm
  • Location: Zoom

Abstract: Femtosecond stimulated Raman spectroscopy (FSRS or fissors) is a form of time-resolved Raman-scattering spectroscopy designed to probe changes in molecular conformation.  Because the energy-level splittings associated with conformational mo… Read More

Seminar: Fluorescent Probes for Spectroscopic Studies of RNA Folding: Not as Innocent as you Think

  • Speaker: Julia Widom
  • Event Type: Seminar
  • Date and Time: 01/11/2021 4:00 pm - 01/12/2021 4:45 pm
  • Location: Zoom

Abstract: Many widely used spectroscopic techniques rely on fluorescence detection, and fluorescence-based methods are particularly useful for the study of biological macromolecules. The nucleic acids RNA and DNA are almost completely nonfluorescent, so a… Read More

Quantization of light in the wave-packet basis; Applications in quantum optics and quantum communications

  • Speaker: Michael Raymer
  • Event Type: Seminar
  • Date and Time: 12/14/2020 3:00 pm - 12/15/2020 3:45 pm
  • Location: Zoom

Abstract: We review the concepts of temporal modes (TMs) in quantum optics, highlighting Roy Glauber's crucial and historic contributions to their development, and their growing importance in quantum information science. TMs are orthogonal sets of wa… Read More
