Event Description 

Laser-cooled trapped ions are among the most versatile experimental platforms for quantum simulation, where its time evolution can be programmed to follow a prescribed Hamiltonian. Internal (e.g. hyperfine) states of ions constitute well isolated qubits or spin-1/2 states with long coherence. Individual spins can be initialized and detected optically with near perfection. Laser-driven coherent spin-phonon couplings allow us to simulate spin Hamiltonians, where the spin-spin interactions can be tuned in magnitude, range, and sign, and in principle can be made arbitrary. The extreme control over spin-spin interactions enable us to investigate a range of frustrated spin systems, where pairwise interactions compete with each other. In this talk, I will describe our experimental effort towards developing a Ytterbium ion based quantum simulator where the interaction graph between the spins can be arbitrarily programmed.
