Research Interests

Akimasa Miyake earned his Ph.D in physics (in particular, quantum information) at the University of Tokyo in Japan. After the postdoctoral activity in the group of Prof. Hans Briegel at the University of Innsbruck in Austria, he started working at Perimeter Institute from the autumn of 2008 when the color of maple trees changed into the Canadian one.

He has worked in quantum computation, quantum information, and theory of entanglement in multipartite systems. His recent research interest focuses on quantum computation in terms of measurements to quantum entanglement. Not only is measurement-based quantum computation widely considered to be a promising route toward physical implementations of a quantum computer, but also its several features distinct conceptually from other quantum computational models make this model really fascinating. For instance, computational complexity reflects directly characteristics of entanglement in the resource state, and an entire space-time structure itself is simulated here. Thus, he expects this approach may lead to answer a fundamental question: ``what is the potential as well as limitations of computation admissible according to the basic laws and structures of nature?''

Especially, he is passionate to progress a recent discovery that the strongly-correlated ground state of such a Hamiltonian that appears in condensed matter physics could serve as a platform of measurement-based computation. That could evolve into quantum information processing through naturally-occurring many-body correlations. At the same time, it may relate the aforementioned question about intertwining physics and information to a modern prevailing perspective of emergence at the quantum many-body systems.
