SUMMARY:Beyond quantum circuits with trapped-ion qubits \, Atomic Phys
ics Seminar\, Or Katz\, Duke University
DESCRIPTION:Trapped ions are a leading quantum technology for quantum
computation and simulation\, with the capability to solve computationa
lly hard problems and deepen our understanding of complex quantum syst
ems. The quantum circuit model is the central paradigm for quantum com
putation\, enabling the realization of various quantum algorithms by a
pplication of multiple one- and two-qubit entangling operations. Howev
er\, the typical number of entangling operations required by this mode
l increases exponentially with the number of qubits\, making it diffic
ult to apply to many problems.
\nIn my presentation\, I will disc
uss new methods for realizing quantum gates and simulations that go be
yond the quantum circuit model. I will first describe a single-step pr
otocol for generating native\, N-body interactions between trapped-ion
spins\, using spin-dependent squeezing. Next\, I will present a prepa
ration of novel phases of matter using simultaneous and reconfigurable
spin-spin interactions. Lastly\, I will explore new avenues to harnes
s the long-lived phonon modes in trapped-ion crystals for simulating c
omplex bosonic and spin-boson models that are difficult to solve using
classical methods. The presented techniques could push the performanc
e of trapped-ion systems to solve problems that are currently beyond t
heir reach.
