Quantum equilibration. This project will shed light on a fundamental problem in physics - how do fragile quantum systems, entirely isolated from the rest of the world, return to equilibrium when disturbed from their natural state? Our results will provide a theoretical underpinning for the development of quantum simulators that can be used for the design of advanced materials.

This project will establish what the uncertainty principle can teach us about quantum foundations, and will address why quantum theory obeys such a principle and why Nature chose quantum theory amongst other possible theories. Specifically, this project will determine how the uncertainty principle restricts the information one can get on incompatible measurements, by deriving new complementarity relations. These will clarify what can or cannot be done in the context of quantum information. This project will determine how much of a theory can be reconstructed from such relations and what other fundamental axioms are required to fully derive quantum theory. This will shed light on the reasons why Nature prefers it to other theories.Read moreRead less

The project intends to provide a solid base of quantum algorithms that would enable quantum computers to tackle currently insurmountable problems. Many of the highest-value applications in computing are based on solving problems in physics. Quantum computers take advantage of the power of quantum mechanics to outperform even the fastest conceivable supercomputers.
