Dear colleagues,
this week we are happy to have Crystal Senko from the Lukin group as speaker at our weekly
seminar.
Kind regards,
Richard and Swati

Directions: after entering the lobby of the CfA, turn right to enter the hallway of the B
building. In the hallway, turn right again, and B-106 is there.
Speaker: Crystal Senko, Harvard University (Lukin group)
Title: Quantum simulations of many-body spin dynamics with trapped ions
Abstract: Trapped atomic ions are a powerful and versatile platform for emulating quantum
spin systems. I will give a brief overview of the tools that are currently available to
experiments, particularly the various spin models that can be generated by applying
spin-dependent optical dipole forces to a chain of interacting ions. We have performed a
variety of experiments using this toolkit, including measurements of the many-body energy
spectrum [1] and of the propagation of spin correlations after a sudden quench [2], as
well as demonstrated a quantum integer-spin chain [3]. This system holds promise for
scaling quantum simulations up to several tens of spins, a size where many classical
computations become intractable.
