This review article summarizes the requirement of low temperature conditions in existing experimental approaches to quantum computation and quantum simulation.
One-way quantum computing is experimentally appealing because it requires only local measurements on an entangled resource called a cluster state. Record-size, but non-universal, continuous-variable cluster states were recently demonstrated…
