Sequential detection of genuine multipartite entanglement is unbounded for entire hierarchy of number of qubits recycled
Chirag Srivastava, Mahasweta Pandit, Ujjwal Sen
Experimental detection of entanglement certainly disturbs the underlying shared state. It is possible that the entanglement content of the system is lost in the process of its dete…
Recycled detection of genuine multiparty entanglement of unlimitedly stretched array of parties and arbitrarily long series of sequential observers
Chirag Srivastava, Mahasweta Pandit, Ujjwal Sen
We consider a scenario where spatially separated observers share a genuinely multiparty entangled quantum state with each local observer possessing a single qubit. A particular qub…
Closing loopholes of measurement-device-independent nonlinear entanglement witnesses
Kornikar Sen, Chirag Srivastava, Ujjwal Sen
The concept of entanglement witnesses form a useful technique to detect entanglement in realistic quantum devices. Measurement-device-independent nonlinear entanglement witnesses (…
Recycled entanglement detection by arbitrarily many sequential and independent pairs of observers
Mahasweta Pandit, Chirag Srivastava, Ujjwal Sen
We investigate the witnessing of two-qubit entangled states by sequential and independent pairs of observers, with both observers of each pair acting independently on their part of…
