Experimentally accessible non-separability criteria for multipartite entanglement structure detection

Guillermo García-Pérez, Oskari Kerppo, Matteo A. C. Rossi +1

The description of the complex separability structure of quantum states in terms of partially ordered sets has been recently put forward. In this work, we address the question of h…

Noisy quantum metrology enhanced by continuous nondemolition measurement

Matteo A. C. Rossi, Francesco Albarelli, Dario Tamascelli +1

We show that continuous quantum nondemolition (QND) measurement of an atomic ensemble is able to improve the precision of frequency estimation even in the presence of independent d…

Quantum frequency estimation with conditional states of continuously monitored independent dephasing channels

Francesco Albarelli, Matteo A. C. Rossi, Marco G. Genoni

We discuss the problem of estimating a frequency via N-qubit probes undergoing independent dephasing channels that can be continuously monitored via homodyne or photo-detection. We…

Pairwise tomography networks for many-body quantum systems

Guillermo García-Pérez, Matteo A. C. Rossi, Boris Sokolov +2

We introduce the concept of pairwise tomography networks to characterise quantum properties in many-body systems and demonstrate an efficient protocol to measure them experimentall…

Efficient quantum transport in a multi-site system combining classical noise and quantum baths

Arzu Kurt, Matteo A. C. Rossi, Jyrki Piilo

We study the population dynamics and quantum transport efficiency of a multi-site dissipative system driven by a random telegraph noise (RTN) by using a variational polaron master…

IBM Q Experience as a versatile experimental testbed for simulating open quantum systems

Guillermo García-Pérez, Matteo A. C. Rossi, Sabrina Maniscalco

The advent of Noisy Intermediate-Scale Quantum (NISQ) technology is changing rapidly the landscape and modality of research in quantum physics. NISQ devices, such as the IBM Q Expe…
