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…

Using a quantum SWAP engine to experimentally validate thermodynamic uncertainty relations
Krishna Shende, Arvind, Kavita Dorai
Thermodynamic uncertainty relations (TURs) arise from the bounds on fluctuations of thermodynamics quantities during a non-equilibrium process and they impose constraints on the co…

ANN-Enhanced Detection of Multipartite Entanglement in a Three-Qubit NMR Quantum Processor
Vaishali Gulati, Shivanshu Siyanwal, Arvind +1
We use an artificial neural network (ANN) model to identify the entanglement class of an experimentally generated three-qubit pure state drawn from one of the six inequivalent clas…
