Quantum Optics Theory Seminar by Naomi Nickerson.

Exquisite quantum control has now been achieved in
small ion traps, in nitrogen-vacancy centers and in superconducting qubit
clusters. We can regard such a system as a universal cell with diverse
technological uses from communication to large-scale computing, provided that
the cell is able to network with others and overcome any noise in the
interlinks. I will discuss network architectures for fault tolerant
quantum computation, where small cells are connected through probabilistic
entanglement generation using optical links, and argue that with
loss-tolerant entanglement purification this is feasible with the noisy and
lossy links that are realistic today.
