SUMMARY:IQUIST Seminar: Three routes to topological long-range entangl
 ement in quantum devices: from Hamilton(ians) to Cayley and Galois\, W
 isconsin Quantum Institute\, Dr. Ruben Verresen\, Harvard University
DESCRIPTION:One of the most remarkable discoveries in the last few dec
 ades is that collections of entangled qubits can form states of matter
  whose topological excitations have anyonic exchange statistics. Despi
 te the importance of such states for quantum information purposes\, th
 ey are extremely challenging to find in materials. In this talk\, we e
 xplore how novel 'bottom-up' quantum devices---built atom by atom\, qu
 bit by qubit---challenge this status quo. Three promising routes are i
 dentified for NISQ devices\, which this talk will exemplify with exper
 imental data on cold ions and Rydberg tweezer arrays. In particular\, 
 long-range entanglement is built through: topological spin liquid grou
 nd states\, non-equilibrium quantum dynamics\, and shallow circuits wi
 th measurements and feedforward. Only the latter is able to avoid deep
  constraints imposed by locality and unitarity\, leading to a surprisi
 ng connection to the unsolvability of the quintic.
