Testing the limits of quantum mechanical superpositions
read the original abstract
Quantum physics has intrigued scientists and philosophers alike, because it challenges our notions of reality and locality--concepts that we have grown to rely on in our macroscopic world. It is an intriguing open question whether the linearity of quantum mechanics extends into the macroscopic domain. Scientific progress over the last decades inspires hope that this debate may be decided by table-top experiments.

Witnessing entanglement between photon and matter due to graviton exchange
A PPT witness criterion is proposed to detect graviton-mediated entanglement between photons and matter qubits, attaining a maximal negativity of -0.052 for non-maximally entangled states when the photon coherent-stat...

Gravitationally Induced Quantum Decoherence of Macroscopic Objects
Gravitational decoherence of macroscopic objects in Newtonian gravity accumulates logarithmically over distances but remains subdominant to collisional decoherence.
