In such cases I attempt to cobble together a details page myself.

"Quantum Communication Networks: the Certifiable Road Ahead."
Tuesday, September 6, 2016
1:00 - 2:00 p.m.
Maxwell Dworkin 119
What precisely is a quantum communication network? While quantum communication
is often associated solely with quantum cryptography, it can enable many other
interesting applications. Here, we propose stages towards the development of a
full blown quantum communication network - a quantum internet. Each stage of
this development is distinguished by the successively larger type of
applications that it supports, and we present tests to certify the successful
attainment of each stage by implementations.
In the second part of this talk we then zoom in further into testing quantum
communication and devices. The first is a procedure which we call capacity
tomography which allows us to estimate the (single shot) capacity of a quantum
communication channel. This procedure is easier than performing full tomography,
and can deal with arbitrarily correlated errors and memory effects in the
quantum devices. The second is to test the performance of local quantum network
nodes, and also quantum computing devices. Concretely, we derive confidence
bounds for the use of randomized benchmarking to characterize quantum gates
which are several orders of magnitude better than previous estimates, enabling
the procedure to be applied to many qubit systems.
Speaker: Stephanie Wehner is an Associate Professor at QuTech, Delft University
of Technology. Her passion is the theory of quantum information in all its
facets, and she has written numerous scientific articles in both physics and
computer science. Stephanie is one the founders of QCRYPT, which has become the
largest conference in quantum cryptography. From 2010 to 2014, her research
group was located at the Centre for Quantum Technologies, National University of
Singapore, where she was first Assistant and later Associate Professor.
Previously, she was a postdoctoral scholar at the California Institute of
Technology in the group of John Preskill. In a former life, she worked as a
professional hacker in industry.
