Nitrogen-vacancy (NV) centers in diamond nanophotonic structures for quantum networking

Edward Chen, Massachusetts Institute of Technology

The exceptional optical and spin properties of the negatively charged nitrogen-vacancy (NV) center in diamond have led to a wide range of hallmark demonstrations ranging from super-resolution imaging to quantum entanglement, teleportation, and sensing. The solid-state environment of the NV allows us to engineer nano-structures that can enhance the properties of the NV and improve the readout and initialization fidelities of the spin.

Jamie Sikora, Centre for Quantum Technologies, National University of Singapore

In this talk, I will discuss correlations that can be generated by performing local measurements on bipartite quantum systems. I'll present an algebraic characterization of the set of quantum correlations which allows us to identify an easy-to-compute lower bound on the smallest Hilbert space dimension needed to generate a quantum correlation. I will then discuss some examples showing the tightness of our lower bound.

Quantum Max-flow/Min-cut

Xingshan Cui, University of California, Santa Barbara

The classical max-flow min-cut theorem describes transport through certain idealized classical networks. We consider the quantum analog for tensor networks. By associating a tensor to each node in an integral flow network, we can also interpret it as a tensor network, and more specifically, as a linear map.

Teaching Quantum Technology word mark

Join us for two days at the Institute for Quantum Computing (IQC) for the Teaching Quantum Technology workshop (TQT) December 5-6. You will have the opportunity to attend lectures and engage in hands-on activities focused on the integration of quantum technology into the current teaching curriculum. We will discuss quantum information science and technology to give you a deeper understanding of quantum mechanics.

Applications of order isomorphisms of C*-algebras

Fred Shultz, Wellesley College

We will review known results about order isomorphisms of C*-algebras,
and will describe some applications to complete positivity of maps and
a generalization of the Choi matrix. (This is joint work with Vern Paulsen.)
Then we will describe some applications to quantum information theory.

A deterministic polynomial time algorithm for word problem for the free skew field

Ankit Garg, Princeton University

We study the word problem for the free skew field of non-commutative rational functions. We prove that an existing algorithm due to Gurvits is actually a deterministic polynomial time algorithm for this problem (over the rationals). Our analysis is simple, providing explicit bounds on the "capacity'' measure of totally positive operators introduced by Gurvits.

The Quantum Innovators workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day workshop aimed at exploring the frontier of our field.

Saturday, October 3, 2015 — 11:00 AM to 4:00 PM EDT

The Institute for Quantum Computing (IQC) will open its doors to all members of the community as part of Reunion at the University of Waterloo. Bring the whole family to discover the excitement of quantum mechanics and learn about the world-class research that is happening right here in our community!

Take a look at what's happening at this year's open house!

Chris Granade

Chris Granade, University of Sydney

In recent years, Bayesian methods have been proposed as a solution to a wide range of issues in quantum state and process tomography. In this talk, we make these methods practical by solving three distinct problems: numerical intractability, a lack of informative prior distributions, and an inability to track time-dependent processes. Our approach allows for practical computation of point and region estimators for quantum states and channels, and allows tracking of time-dependent states.

Friday, September 11, 2015 — 2:00 PM EDT
Jihyun (Annie) Park

Jihyun Park of the Department of Physics and Astronomy will be defending his thesis:
