Seminar

Scientists of all backgrounds and genders, have made important contributions in science, technology, engineering and mathematics (STEM), but the participation of women remains low in many areas of STEM, including physics. What can we do to build an inclusive STEM community? Shohini Ghose, IQC associate and Director of the Laurier Centre for Women in Science (WinS) will discuss data that can shed light on where we stand today and describe a practical framework for increasing access and inclusion in STEM.

In partnership with the Kitchener Public Library, join John Donohue for a conversation with author and researcher Chad Orzel. They'll be talking about Orzel's latest book, A Brief History of Timekeeping.

About the book:
Sharp and engaging, A Brief History of Timekeeping is a story not just about the science of sundials, sandglasses, and mechanical clocks, but also the politics of calendars and time zones, the philosophy of measurement, and the nature of space and time itself.

Join us for Quantum Today, where we sit down with researchers from the University of Waterloo’s Institute for Quantum Computing (IQC) to talk about their work, its impact and where their research may lead.

Observation and manipulation of a phase separated state in a charge density wave material

Conformal symmetry of fields near the event horizon of the black hole plays a significant role in determining the temperature of the black hole radiation. In this talk, we show how the near-horizon (NH) conformal symmetry provides a microscopic theory for the area-entropy relation for any static or stationary black hole. To do that, we map the NH behavior of the field modes to the scale-invariant Hamiltonian of conformal quantum mechanics (CQM).

In cavity quantum electrodynamics (cavity QED) systems, the realization of strong coupling between light and atoms plays a critical role in the study of quantum optics and entanglement. At the same time, Rydberg atom arrays provide a promising platform for exploring quantum many-body physics. However, with the Rydberg-mediated interactions, atoms mainly interact locally. Coupling Rydberg arrays to a cavity opens up new research directions in quantum many-body physics with long-range interactions, creating a fully connected quantum network.

Optimal Theory Control Techniques for Nitrogen Vacancy Ensembles 

Nitrogen Vacancy (NV) Centers in diamond are a very versatile tool. A single Nitrogen Vacancy center is most notably known for sensing magnetic fields, but recently has presented itself as a functional node for a quantum internet, to name just two of its wide ranges of applications.
