I will introduce a scheme for assessing the non-classicality of the inaccessible objects as characterised by quantum discord. I will consider two probes individually interacting with the inaccessible object, but not with each other. The scheme is based on monitoring entanglement dynamics between the probes, is robust and experimentally friendly as it allows the probes and the object to be open systems, makes no assumptions about the initial state, dimensionality of involved Hilbert spaces and details of the probe-object Hamiltonian.

I will illustrate its potential using a membrane-in-the-middle optomechanical system to detect system-environment correlations in open system dynamics as well as non-classicality of the environment, and I will foresee potential benefits for the inference of the non-classical nature of gravity.

Short Bio: 

Prof. Mauro Paternostro received his PhD in 2005 from QUB. He was then a Leverhulme Trust Early Career Fellow (2005-2008) at QUB and Universitaet Wien (Austria), an EPSRC Career Acceleration Fellow at Queen’s University Belfast (QUB, 2008-2014) and has been awarded an Alexander von Humboldt Fellowship for Senior Scientists in 2011. He became Lecturer in Quantum Optics and Quantum Information Science at QUB in 2008, Reader in 2012, and Full Professor in 2013. He is currently Director of Research of CTAMOP. He has authored 170+ research papers published in top-tier international journals (including Nature, Phys. Rev. Lett.,

Nature Quantum Information, and New J. Phys.). He has attracted 6500+ citations (source Google Scholar) and € 6.5M+ of research funding from various sources. He has significantly contributed to the investigations on quantum effects in mesoscopic systems, nonclassical correlations, linear optics quantum computing, quantum optomechanics, and non-equilibrium quantum thermodynamics. He is the Chief Editor of the De Gruyter journal “Quantum Measurement and Quantum Metrology” and a member of the Editorial Board of Scientific Reports. He has held Visiting Professor positions at Sapienza University of Rome (Italy), Universitaet Ulm (Germany), the Federal University of ABC (Sao Paulo, Brazil), and the Ecole Normale Superieure (France).
