Feedback control of quantum entanglement in a two-spin system
— A pair of spins is the most simple quantum system that can possess entanglement, a non-classical property playing an essential role in quantum information technologies. In this...

Quantum Patterns and Types for Entanglement and Separability
As a first step toward a notion of quantum data structures, we introduce a typing system for reflecting entanglement and separability. This is presented in the context of classi...

Regulation and tracking of two-level quantum systems using measurement feedback
Abstract— Two-level quantum systems are important quantum models that are useful for the conceptual development and construction of quantum technologies. In this paper we provide...

Is measurement-based feedback still better for quantum control systems?
In this paper, we put forward a fundamental question concerning feedback control of quantum systems: Is measurement-based feedback control still better than openloop control? In c...

Feedback interconnection of open quantum systems: A small gain theorem
Abstract— This paper examines the stability of quantum feedback networks. We introduce a novel characterization, in terms of equivalence classes of operators, that may be used to...
