Experimental demonstration of quantum gain in a zero-sum game
Abstract: We propose and experimentally demonstrate a zero-sum game which is in a fair Nash equilibrium for classical players, but a quantum player can always win using an appropriate strategy. The g...

Quantum many-body phases with trapped ions and cold atoms
Abstract: Trapped ions and cold atoms which are highly controllable offer us the most reliable and scalable quantum simulators. In this talk I will discuss firstly how to use trapped ions interacting...
