In particular, we show that the flow of thermal phonons across such structures can be controlled and directed by a proper tuning of the reservoir’s driving phase. By considering optomechanical units as our pivotal building block, we investigate the control of cavity-mediated particle transport in lattices of cavity-coupled optomechanical resonators, where the optical modes behave as a controlled nonlocal reservoir. Within the Lindblad master equation framework, we derive general model-independent expressions for the coherent and incoherent processes mediated by such controlled driven-dissipative reservoirs and provide an effective description of the reduced dynamics of the system modes. In particular, we address the case of Markovian coherent quantum extended reservoirs. We study the broad problem of the dynamics of bipartite ensembles consisting of a set of independent system modes of interest that are coupled to some spatially extended driven-dissipative reservoir. This thesis is devoted to the study of reservoir-induced dynamics in open quantum systems and to machine learning with classical photonic reservoirs. Rather than introducing these concepts from a rigorous mathematical and computer science framework, we instead examine error correction and fault-tolerance largely through detailed examples, which are more relevant to experimentalists today and in the near future. The development in this area has been so pronounced that many in the field of quantum information, specifically researchers who are new to quantum information or people focused on the many other important issues in quantum computation, have found it difficult to keep up with the general formalisms and methodologies employed in this area. In response, we have attempted to summarize the basic aspects of quantum error correction and fault-tolerance, not as a detailed guide, but rather as a basic introduction. However, quantum error correction and fault-tolerant computation is now a much larger field and many new codes, techniques, and methodologies have been developed to implement error correction for large-scale quantum algorithms. The introduction of quantum error correction in 1995 showed that active techniques could be employed to mitigate this fatal problem. It was well known from the early developments of this exciting field that the fragility of coherent quantum systems would be a catastrophic obstacle to the development of large-scale quantum computers. Quantum error correction (QEC) and fault-tolerant quantum computation represent one of the most vital theoretical aspects of quantum information processing.
