Evolution of different orders of coherence of a three-qubit system and their protection via dynamical decoupling on an NMR quantum processor
Akanksha Gautam, Kavita Dorai, Arvind
We generate different orders of quantum coherence in a three-qubit NMR system and study their dynamics in the presence of inherent noise. Robust dynamical decoupling (DD) sequences…
Experimental demonstration of the dynamics of quantum coherence evolving under a PT-symmetric Hamiltonian on an NMR quantum processor
Akanksha Gautam, Kavita Dorai, Arvind
In this work, we study the dynamics of quantum coherence (total coherence, global coherence and local coherence) evolving under a local PT-symmetric Hamiltonian in maximally entang…
Protection of noisy multipartite entangled states of superconducting qubits via universally robust dynamical decoupling schemes
Akanksha Gautam, Arvind, Kavita Dorai
We demonstrate the efficacy of the universally robust dynamical decoupling (URDD) sequence to preserve multipartite maximally entangled quantum states on a cloud based quantum comp…
Simulating the effect of weak measurements by a phase damping channel and determining different measures of bipartite correlations in nuclear magnetic resonance
Akanksha Gautam, Varad R. Pande, Amandeep Singh +2
Quantum discord is a measure based on local projective measurements which captures quantum correlations that may not be fully captured by entanglement. A change in the measurement…
Experimental Detection of Qubit-Ququart Pseudo-Bound Entanglement using Three Nuclear Spins
Amandeep Singh, Akanksha Gautam, Arvind +1
In this work, we experimentally created and characterized a class of qubit-ququart PPT (positive under partial transpose) entangled states using three nuclear spins on an nuclear m…
