Seminar

An introduction to making scientific figures with Illustrator and Blender

Special guest speaker: Christopher Gutierrez, University of British Columbia

Scientific research can be a slow and laborious process. The absolutely final step in the process is to then communicate your exciting scientific findings to other scientists both in and outside of your field. Yet it is often at this final step where the least amount of time is spent.

Title: Dynamic nuclear polarization in phosphorus doped silicon

Junichiro Kono, Rice University

Recent experiments have demonstrated that light and matter can mix together to an extreme degree, and previously uncharted regimes of light-matter interactions are currently being explored in a variety of settings, where new phenomena emerge through the breakdown of the rotating wave approximation [1]. This talk will summarize a series of experiments we have performed in such regimes.

The development of atom-like quantum sensors in wide bandgap materials, for instance Nitrogen Vacancy (NV) centers in diamond, has thrown up exciting new possibilities for the sensing of materials, molecules and biological systems through optical means. In particular I will describe the development of “quantum-assisted” magnetic resonance probes based on the NV center that allows sensing of nano- and meso-scale volumes at high spatial and frequency resolution [1,2].

Inevitably, assessing the overall performance of a quantum computer must rely on characterizing some of its elementary constituents and, from this information, formulate a broader statement concerning more complex constructions thereof. However, given the vastitude of possible quantum errors as well as their coherent nature, accurately inferring the quality of composite operations is generally difficult.

Arthur Mehta, IQC / Department of Pure Mathematics

In this talk we continue our discussion of parallel repetition for non-local games. We will begin with a brief recap of the previous talk and the famous counterexample due to Feige. We then take a  look at a game that has interesting outcomes in the context of the quantum tensor product model. We will conclude by reviewing some of the major results on this topic for a variety of correlation sets.

Alex Ruichao Ma, University of Chicago

Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. Here we apply this toolbox to the exploration of strongly correlated quantum materials made of microwave photons. We develop a versatile recipe that uses engineered dissipation to stabilize many-body phases, protecting them against intrinsic photon losses.

Silicon MOSFET quantum dots with simplified metal-gate geometry

Eduardo Barrera

Silicon (Si) CMOS spin qubits have become a promising platform for a future quantum information processor due to recent demonstrations of high fidelity single and two qubit gates [Veldhorst et. al., Nature 526.7573 (2015)], compatibility with industrial CMOS process and promising prospects for scalability.

Wen Huang, Shenzhen Peng Cheng Laboratory

Since its discovery in 1994, the unconventional superconductivity in Sr2RuO4 has attracted tremendous interest. The prospect of it being a topological chiral p-wave superconductor, which supports Majorana fermions, makes it a potential solid state platform for topological quantum computation. However, despite the multiple signatures in support of chiral p-wave pairing, a number of key measurements in the last decade have called into question this interpretation.

Alan Jamison, Massachusetts Institute of Technology (MIT)

Cooling atomic gases to quantum degeneracy opened the new field of quantum simulation. Here the precise tools of atomic physics can be used to study exotic models from condensed matter or nuclear physics with unique tunability and control. Ultracold molecules bring many new possibilities to quantum simulation. I will review the physics of ultracold molecules, including our recent production of stable, ultracold triplet molecules and what they can add to quantum simulation.
