Detecting entanglement harnessing Lindblad structure
Vaibhav Chimalgi, Bihalan Bhattacharya, Suchetana Goswami +1
The problem of entanglement detection is a long standing problem in quantum information theory. One of the primary procedures of detecting entanglement is to find the suitable posi…
Experimental demonstration of one-sided device-independent self-testing of any pure two-qubit entangled state
Zhihao Bian, A. S. Majumdar, C. Jebaratnam +5
We demonstrate one-sided device-independent self-testing of any pure entangled two-qubit state based on a fine-grained steering inequality. The maximum violation of a fine-grained…
Protecting quantum correlations in presence of generalised amplitude damping channel: the two-qubit case
Suchetana Goswami, Sibasish Ghosh, A. S. Majumdar
Any kind of quantum resource useful in different information processing tasks is vulnerable to several types of environmental noise. Here we study the behaviour of quantum correlat…
Universal detection of entanglement in two-qubit states using only two copies
Suchetana Goswami, Sagnik Chakraborty, Sibasish Ghosh +1
We revisit the problem of detection of entanglement of an unknown two-qubit state using minimal resources. Using weak values and just two copies of an arbitrary two-qubit state, we…
One-sided Device-independent Self-testing of any Pure Two-qubit Entangled State
Suchetana Goswami, Bihalan Bhattacharya, Debarshi Das +3
We consider the problem of -sided device-independent self-testing of any pure entangled two-qubit state based on steering inequalities which certify the presence of quantum stee…
