QT-2-26-1 / Quantum optical archaeology: Mesuring how much time atoms spent in forbiden region and how much time photons spent inside atoms
* Aephraim Steinberg, University of Toronto, Canada
QT-2-26-2 / Entanglement from the quantum internet to quantum neuroscience
* Christoph Simon, University of Calgary, Canada
I describe recent research in my group on quantum networks and quantum biology. Entanglement is an important guiding concept in both of these areas.

We report the emergence of a photonic-based time crystal (TC) in multi-particle cyclic quantum systems, whose dynamics are described by discrete time quantum walks. We introduce experimental evidence in which periodically driven systems in one-dimensional closed structures qualify as potential candidates for photonic-based TCs. In particular, a dynamical one-dimensional Ising-like model combined with a hopping mechanism driven by a unitary quantum walk step operator is proposed to realize the spontaneous breaking of time translation symmetry. The time evolution of the particles in the TC is simulated using photons in coherent states and a number of special cases is discussed.
