The goal of this project was to begin preliminary testing of a theoretical procedure for improving coherence in quantum systems. The procedure was put forward by Marshall, Campos Venuti, and Zanardi in their2017 PRA. It specifies adding a new type of noise, termed generalized Markovian noise, to a quantum system in order to counteract decoherence due to Markovian background noise. Several types of corrective generalized Markovian noise have been proposed. In this project, we had the goal of developing a testbed for screening these noise recipes. A secondary goal was to test the simplest noise recipe--adding Poisson telegraph noise--and see if coherence could be improved. Finally, we had the goal of determining future paths in experimental and theoretical research into this topic, to be continued with a possible full ARO grant.
