Non-Markovianity-based ultrasensitive parameter estimation
Olli Siltanen
Accurate parameter estimation is a central task in quantum metrology and sensing, where quantum resources can provide precision beyond classical limits. In realistic settings, howe…
Overcoming noise in quantum teleportation with multipartite hybrid entanglement
Zhao-Di Liu, Olli Siltanen, Tom Kuusela +5
Quantum entanglement and decoherence are the two counterforces of many quantum technologies and protocols. For example, while quantum teleportation is fueled by a pair of maximally…
Experimental Snapshot Verification of non-Markovianity with Unknown System-Probe Coupling
Henri Lyyra, Olli Siltanen, Jyrki Piilo +2
We apply the recently proposed quantum probing protocols with an unknown system-probe coupling to probe the convex coefficients in mixtures of commuting states. By using two refere…
Engineering of Hong-Ou-Mandel interference with effective noise
Olli Siltanen, Tom Kuusela, Jyrki Piilo
The Hong-Ou-Mandel effect lies at the heart of quantum interferometry, having multiple applications in the field of quantum information processing and no classical counterpart. Des…
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…
Entanglement Protection via Periodic Environment Resetting in Continuous Time Quantum Dynamical Processes
Thomas Bullock, Francesco Cosco, Marwan Haddara +8
The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a coup…
