Future students

Informal conversation with Dr. Milena Grifoni, University of Regensburg

​Presented by: Fem Phys and Women in Science

​Join Fem Phys and Women in Science for an informal conversation with Dr. Milena Grifoni about her career in physics. Dr. Grifoni researches quantum transport in nanoscale systems and quantum dissipation at the University of Regensburg in Germany. Coffee and cookies will be provided. All are welcome. 

Airborne demonstration of a QKD payload receiver

Chris Pugh, IQC

We demonstrate the viability of components of a quantum receiver satellite payload by successfully performing quantum key distribution in an uplink configuration to an airplane. Each component has a clear path to flight for future satellite integration.

Short film festival + public lecture by Martin Laforest

Join us for a night of film and science. The Institute for Quantum Computing has partnered with the Centre for Quantum Technologies in Singapore to host a festival for quantum-inspired films. The screening of the top 10 short films will be followed by a lecture by Senior Manager, Scientific Outreach, Martin Laforest about the applications of quantum devices. He will delve into what we know quantum devices will be used for (that will affect everyone) and where researchers are hoping they will be used in the future.

Probing light-matter entanglement in the non-perturbative regime of a strongly driven spin-boson system

Milena Grifoni, University of Regensburg

The spin-boson model is an archetype model to study the impact of a thermal reservoir on the coherent dynamics of a two-level quantum particle. When the coupling between qubit and environment crosses a threshold, a transition from coherent to incoherent tunneling between the two qubit eigenstates occurs. At even larger coupling, the dynamics is fully quenched, signaling a strong entanglement of the qubit with the reservoir’s continuum.

Real-time dynamics of lattice gauge theories with a few-qubit quantum computer

Christine Muschik, University of Innsbruck

Gauge theories are fundamental to our understanding of interactions between the elementary constituents of matter as mediated by gauge bosons. However, computing the real-time dynamics in gauge theories is a notorious challenge for classical computational methods. In the spirit of Feynman's vision of a quantum simulator, this has recently stimulated theoretical effort to devise schemes for simulating such theories on engineered quantum-mechanical devices, with the difficulty that gauge invariance and the associated local conservation laws (Gauss laws) need to be implemented.

The Quantum Key Distribution (QKD) Summer School, hosted by IQC, equips graduate students and young postdoctoral fellows with a strong foundation in quantum communication, particularly quantum cryptography.

An inversion-symmetry-broken order inside the pseudogap region of a cuprate revealed by optical second harmonic generation

Liuyan Zhao, University of Michigan

The phase diagram of cuprate high-temperature superconductors features an enigmatic pseudogap region that is characterized by a partial suppression of low-energy electronic excitations. In order to understand its microscopic nature, it is imperative to identify the full symmetries both prior to and within the pseudogap region. In this talk, I will describe our experimental results of symmetry properties on YBa2Cu3Oy across a wide temperature and doping range using a recently developed nonlinear optical rotational anisotropy technique.

The Women in Physics Canada (WIPC) conference, hosted by the University of Waterloo, Faculty of Science, Department of Physics & Astronomy and the Institute for Quantum Computing, will bring together early career scientists to present their research and hear plenary talks from leaders in physics.

We welcome attendance by people of all genders.

Principles of AFM and its applications

Deler Langenberg, IQC

Experiments designed to prove certain ideas have often ended up showing them to be wrong. Consequently, all physical concepts must be verified experimentally if they are to be accepted as representing laws of nature.

Accordingly, the goals of my talk are:

First, To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.

Quantum entanglement for precision sensing with atoms and light

Onur Hosten, Stanford University

In the last decades, advances in the level of precision in controlling atomic and optical systems opened up the low-energy precision frontier to fundamental physics tests in addition to yielding new applied sensing technologies. In this talk I will focus on our experiments with cold atoms highlighting some of the most recent developments in the prospect of using quantum entanglement to further improve the precision of atomic and optical sensors.
