The Series Product and Its Application to Quantum Feedforward and Feedback Networks (2007, background): “Because of new imperatives concerning quantum network analysis and design, in particular, quantum feedback control, [4], [12], [17], [18], [23]–[26] the purpose of this paper is to present simple and general algebraic methods for describing series connections in quantum networks.”
Quantum feedback: theory, experiments, and applications (2014, background): “A second notion of feedback control without explicit measurements was introduced by Lloyd in 2000 [57].”
H-Infinity Control of Linear Quantum Stochastic Systems (2007, neutral): “tions which inﬂuence the dynamics of the quantum system in a feedback loop. In contrast, quantum controllers are themselves quantum systems, and the closed loop is fully quantum; e.g., see [5], [11], [18], [27]–[29]. Our approach involves deriving a quantum version of the Strict Bounded Real Lemma (”
Training Schrödinger’s cat: quantum optimal control (2015, methodology): “Controlling a quantum system by feedback in a closed loop can be realized in two different ways [453] – using the measurement-based feedback approach [446] or the coherent feedback method [258].”
Quantum control theory and applications: A survey (2009, neutral): “ussions on open-loop quantum control focus on coherent control where we can manipulate the state of a quantum system by applying semiclassical potentials in a fashion that preserves quantum coherence [17]. The control inputs commonly occur as tunable parameters in the Hamiltonian of the system and c”
Feedback for physicists: A tutorial essay on control (2005, background): “Lloyd has emphasized that one can imagine a fully quantum feedback scheme wherein one adds an element to the quantum system that interacts (without making a measurement) with it in such a way that the dynamics are altered in a desired way (Lloyd, 2000).”
$H^{\infty}$ Control of Linear Quantum Stochastic Systems (2007, background): “In contrast, quantum controllers are themselves quantum systems, and the closed loop is fully quantum; e.g., see [5], [10], [18], and [28]–[31].”
