Interferometric Approach to Open Quantum Systems and Non-Markovian Dynamics
O. Siltanen, T. Kuusela, J. Piilo
We combine the dynamics of open quantum systems with interferometry and interference introducing the concept of open system interferometer. By considering a single photon in a Mach…
Experimental Quantum Probing Measurements With No Knowledge on the System-Probe Interaction
Henri Lyyra, Olli Siltanen, Jyrki Piilo +2
In any natural science, measurements are the essential link between theory and observable reality. Is it possible to obtain accurate and relevant information via measurement whose…
Distributing Memory Effects in an Open Two-Qubit System
O. Siltanen, T. Kuusela, J. Piilo
We introduce a method to distribute memory effects among different subspaces of an open two-qubit system's state space. Within the linear optical framework, our system of interest…
Obtaining conclusive information from incomplete experimental quantum tomography
Henri Lyyra, Tom Kuusela, Teiko Heinosaari
We demonstrate that incomplete quantum tomography can give conclusive information in experimental realizations. We divide the state space into a union of multiple disjoint subsets…
