Toward the first quantum simulation with quantum speedup

Neil Julien Ross, Dalhousie University

As we approach the development of a quantum computer with tens of
well-controlled qubits, it is natural to ask what can be done with
such a device. Specifically, we would like to construct an example of
a practical problem that is beyond the reach of classical computers,
but that requires the fewest possible resources to solve on a quantum
computer. We address this problem by considering quantum simulation of
spin systems, a task that could be applied to understand phenomena in

Colloquium: Search for a toric code topological order in the kagome antiferromagnet

Jiawei Mei - Southern University of Science and Technology, China

The toric code is a topological quantum error correcting code, and an example of a stabilizer code, defined on a two-dimensional spin lattice. It also represents the simplest example of topological order -- Z2 topological order that was first studied in the context of Z2 spin liquid. I will talk about our recent progress in the search for a toric code topological order in the kagome antiferromagnetic spin system.

CryptoWorks21 - Intellectual Property: What is it and Why Should I Care?

Back by popular demand, CryptoWorks21 will once again launch the Intellectual Property (IP) Management Lunch and Learn Lecture Series! Our knowledgeable speakers will provide more in-depth presentation built from the previous sessions.

The lectures are designed for researchers working in areas related to information technology, including cryptography and quantum technology.

The NV center in diamond: a versatile quantum technology

Colloquium: Ania Jayich, University of California, Santa Barbara

The nitrogen vacancy (NV) center in diamond is an atomic-­scale defect that exhibits remarkably coherent quantum properties in a uniquely accessible way: at room temperature, in ambient conditions, and even immersed in biological environments. NV centers are being explored for a variety of quantum technologies, including quantum sensing and quantum information processing.

Topological photonics: classical to quantum

Colloquium: Mohammad Hafezi, University of Maryland/Joint Quantum Institute

There are tremendous efforts underway to better understand systems with topological order --- global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems, where insensitivity to local properties manifests itself as conductance through edge states which are insensitive to defects and disorder.

Shining Light on Perovskite Chalcogenides

Colloquium: Jayakanth Ravichandran - University of Southern California

Perovskite Chalcogenides are a new class of semiconductors, which have tunable band gap in the visible to infrared part of the electromagnetic spectrum. Besides this band gap tunability, they offer a unique opportunity to realize large density of states semiconductors with high carrier mobility. In this talk, I will discuss some of the advances made both in my research group and in the research community in theory, synthesis of these materials and understanding their optoelectronic properties.
