A distinguished and prolific scientist, Dr. Nielsen specializes in Quantum Information Theory and is widely known for his fundamental work on the theory of entangled quantum states, which are the essential physical resource underlying quantum information processing. His majorization theorem is a fundamental tool used by researchers to classify and compare the power of different entangled quantum states.

He is author or co-author of 53 papers either published or accepted for publication in international refereed journals since 1996, with 1426 citations. His comprehensive textbook, “Quantum Computation and Quantum Information” (Cambridge University Press, 2000, co-authored with I.L. Chuang) is considered by many to be the most significant textbook on quantum information currently available.

Dr. Nielsen (PhD New Mexico, 1998) is currently the Australian Research Council Federation Fellow in the School of Physical Sciences at the University of Queensland. He will join PI as Faculty beginning May, 2007.


Talks by Michael Nielsen

Cultural openness and its connection to online innovation in science

How can we best take advantage of the internet to improve how science is done? Much attention has been paid to open access and open data as enablers of online innovation. In this talk, I discuss the complementary issue of cultural openness in science, and argue that a relatively closed culture is inhibiting online innovation in science. I\'ll discuss ways this culture may be changed, and what opportunities may result.

Quantum computation as geometry

How should we think about quantum computing? The usual answer to this question is based on ideas inspired by computer science, such as qubits, quantum gates, and quantum circuits. In this talk I will explain an alternate geometric approach to quantum computation. In the geometric approach, an optimal quantum computation corresponds to "free falling" along the minimal geodesics of a certain Riemannian manifold.
