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…

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…
