Statistical Correlators and Tripartite Entanglement

Sakil Khan, Dipankar Home, Urbasi Sinha +1

It has recently been argued that among the various suggested measures of tripartite entanglement, the two particular measures, viz. the Concurrence Fill and the Genuine Multipartit…

Testing Whether Gravity Acts as a Quantum Entity When Measured

Farhan Hanif, Debarshi Das, Jonathan Halliwell +4

A defining signature of classical systems is "in principle measurability" without disturbance: a feature manifestly violated by quantum systems. We describe a multi-interferometer…

Mass-Independent Scheme to Test the Quantumness of a Massive Object

Debarshi Das, Dipankar Home, Hendrik Ulbricht +1

The search for empirical schemes to evidence the nonclassicality of large masses is a central quest of current research. However, practical schemes to witness the irreducible quant…

Spatial Qubit Entanglement Witness for Quantum Natured Gravity

Bin Yi, Urbasi Sinha, Dipankar Home +2

Evidencing the quantum nature of gravity through the entanglement of two masses has recently been proposed. Proposals using qubits to witness this entanglement can afford to bring…

Wigner's approach enabled detection of multipartite nonlocality using all different bipartitions

Sumit Nandi, Debashis Saha, Dipankar Home +1

Distinct from Bell's approach, Wigner had derived a form of local realist (LR) inequality which is quantum mechanically violated for a bipartite maximally entangled state. Subseque…

Unambiguous joint detection of spatially separated properties of a single photon in the two arms of an interferometer

Surya Narayan Sahoo, Sanchari Chakraborti, Som Kanjilal +3

The quantum superposition principle implies that a particle entering an interferometer evolves by simultaneously taking both arms. If a non-destructive, minimally-disturbing intera…
