Colloquium

Big Ideas for Little Minds

Chris Ferrie will take you through a historical journey of his own coming of age with digital software and what that experience has granted him. The lesson to be learned is that children will take advantage of the opportunities they are given, but only if their parents and teachers show genuine interest in the activities giving rise to those opportunities. 20 years from now, there will be a Quantum Technology equivalent of Bill Gates. That future leader is only a young child today.

IQC Colloquium - Layla Hormozi, IQC

We study the role of Hamiltonian complexity in the performance of quantum annealers. It is well-known that non-stoquastic Hamiltonians are more complex than stoquastic Hamiltonians and universal adiabatic quantum computing is possible when they are employed. Here we ask whether utilizing non-stoquastic Hamiltonians in quantum annealers can lead to a better performance in solving optimization problems.

In ordinary, non-relativistic quantum theory, especially in quantum information, space and time are treated differently. For example, time is a parameter rather than an operator; states are defined across the whole space but only at one time, and then evolve under the prescribed dynamics. These go against our intuition from relativity. Thus, space-time density matrices have been introduced and here we discuss one of these formulations called pseudo-density matrix (PDM) which treats space and time indiscriminately.
