Abstract:
The magnetic order of interacting quantum spins is of fundamental interest in many
areas of physics, and it is related to several exotic material phenomena, such as
quantum phase transitions, magnetic frustration, and high Tc superconductivity.
Theoretical studies on those exotic phenomena would demand a quantum computer
or a quantum simulator. Trapped ion systems has recently been identified as a
promising physical implementation of a problem specific quantum simulator, thanks
to the strong and tunable graph couplings between ions and its advanced status on
quantum computation applications. We will discuss our most recent results of
quantum simulations of Ising spin in a transverse magnetic field with three trapped
Ytterbium ions. We will also discuss on how this system may be scaled up to a
much larger number of spins.
