Trapped ions are a promising candidate system to realize a scalable quantum computer. We present a modular quantum computing architecture comprised of a chain of 171Yb+ ions with individual Raman beam addressing and individual readout.
We use the transverse modes of motion in the chain to produce entangling
gates between any qubit pair. This creates a fully connected system which can
be configured to run any sequence of single- and two-qubit gates, making it in
effect an arbitrarily programmable quantum computer that does not suffer any
Recent results from different quantum algorithms on five and seven ions
will be presented, including current work in quantum machine learning. I
will also discuss schemes to scale up this architecture, as well as other ideas
for the future.
