Experimental demonstration of selective quantum process tomography on an NMR quantum information processor
Akshay Gaikwad, Diksha Rehal, Amandeep Singh +2
We present the first NMR implementation of a scheme for selective and efficient quantum process tomography without ancilla. We generalize this scheme such that it can be implemente…

Witnessing nonclassical correlations via a single-shot experiment on an ensemble of spins using NMR
Amandeep Singh, Arvind, Kavita Dorai
A bipartite quantum system in a mixed state can exhibit nonclassical correlations, which can go beyond quantum entanglement. While quantum discord is the standard measure of quanti…
