Non-Markovianity in High-Dimensional Open Quantum Systems using Next-generation Multicore Optical Fibers [PDF]
QuantumWith the advent of quantum technology, the interest in communication tasks assisted by quantum systems has increased both in academia and industry. Nonetheless, the transmission of a quantum state in real-world scenarios is bounded by environmental noise,

Advances in Sequential Measurement and Control of Open Quantum Systems
Proceedings, 2019 Novel concepts, perspectives and challenges in measuring and controlling an open quantum system via sequential schemes are shown. We discuss how similar protocols, relying both on repeated quantum measurements and dynamical decoupling control pulses, can

Repeated interactions in open quantum systems
, 2013 Analyzing the dynamics of open quantum systems has a long history in mathematics and physics. Depending on the system at hand, basic physical phenomena that one would like to explain are, for example, convergence to equilibrium, the dynamics of quantum ...

Complete Characterization of a Quantum Process: the Two-Bit Quantum Gate [PDF]
, 1996 We show how to fully characterize a quantum process in an open quantum system. We particularize the procedure to the case of a universal two-qubit gate in a quantum computer.

Bound on the distance between controlled quantum state and target state under decoherence
Journal of Physics CommunicationsTo implement quantum information technologies, carefully designed control for preparing a desired state plays a key role. However, in realistic situation, the actual performance of those methodologies is severely limited by decoherence.
