Colloquium featuring Carl Alexander Miller - QuICS and NIST

How can two parties carry out a fair coin flip across a noiseless quantum channel? In 2007, Carlos Mochon proved a tantalizing result: he showed that fair quantum coin flipping is possible in principle, but he used a protocol that required a huge (exponential) number of communication rounds. In the twelve years since, despite some continued deep theoretical work on the problem, no improvements to the efficiency of Mochon's protocol have been made.

In July 2020, Raymond Laflamme will turn 60. To celebrate this milestone, an anniversary conference is in order. Ray’s main wish is to hear from his former students and postdocs. We therefore decided to invite exclusively people who, at one point or another in their career, were under the mentorship of this accomplished scientist.

Join us for an intimate conversation featuring IQC researchers. Our first guest is Professor Raymond Laflamme, interviewed by John Donohue. John and Raymond will have a conversation about research, careers, and life in quantum information science, followed by Q&A from the audience. Tune in Tuesday August 11 at 7:00pm Eastern Time.

Webex Seminar - Zheng Shi, Free University of Berlin

A one-dimensional topological superconductor hosts a pair of Majorana bound states at its ends, forming a fermionic level which stores the fermion parity information nonlocally. Consequently, in the Coulomb blockade regime, Majorana-assisted single-electron tunneling can remain coherent well beyond the coherence length of the superconductor.

The profound impact of early discovery, experimentation, and disruption through research and invention

Researchers today build on the knowledge and discoveries made by those who have come before them. How can today’s researchers light the early pathways and curiosities for the research breakthroughs of the future? How can we demonstrate the impact and potential of the yet-to-be known? And, what if any, role does academia, industry, the Faculty of Mathematics, and Canada play in increasing the discovery journey to these new frontiers?

Join us for casual conversations with researchers at the Institute for Quantum Computing (IQC).

Shayan Majidy, PhD candidate - Tuesday, September 29, 7:00 p.m.

This month, we welcome PhD student Shayan Majidy for a conversation about life as a graduate student, and what it's like to share quantum and science with a young audience.

Liyuan Qiu, Institute for Interdisciplinary Information Sciences, Tsinghua University

In this talk, I will introduce three non-equilibrium dynamics experiments in the anti-ferromagnetic spin-1 sodium condensate, including one experiment about the Kibble-Zurek mechanism in the first-order quantum phase transition and two experiments about Dynamical Quantum Phase Transitions.

In the Kibble-Zurek mechanism, we find out that not only the ground state matters in quantum phase transition but also the high excited states matter.

From Laser Cooling to Quantum Chemistry

Lasers are used in factories for burning through metal and in movies for blowing up space ships. But in the lab, we use them to cool atoms down to within one billionth of a degree of absolute zero.

Join us for casual conversations with researchers at the Institute for Quantum Computing (IQC).

Kristine Boone, PhD candidate - Tuesday, October 20, 7:00 p.m.

For our third Fireside Chat, we welcome Kristine Boone for a conversation about working on the boundary of research and industry.

Tune in live on YouTube.

PI/IQC Joint Colloquium on Zoom, featuring Norbert Matthias Linke, University of Maryland 

We present a quantum architecture based on a linear chain of trapped 171Yb+ ions with individual laser beam addressing and readout. The collective modes of motion in the chain are used to efficiently produce entangling gates between any qubit pair. In combination with a classical software stack, this becomes in effect an arbitrarily programmable and fully connected quantum computer. The system compares favorably to commercially available alternatives [2].
