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…
Experimental decoherence mitigation using a weak measurement-based scheme and the duality quantum algorithm
Gayatri Singh, Akshay Gaikwad, Arvind +1
We experimentally demonstrate a weak measurement and measurement reversal-based scheme to ameliorate the effects of decoherence due to amplitude damping, on an NMR quantum processo…
Ground and excited state energy calculations of the H2 molecule using a variational quantum eigensolver algorithm on an NMR quantum simulator
Dileep Singh, Shashank Mehendale, Arvind +1
Variational quantum algorithms are emerging as promising candidates for near-term practical applications of quantum information processors, in the field of quantum chemistry. We im…
Experimental quantum state transfer of an arbitrary single-qubit state on a cycle with four vertices using a coined quantum random walk
Gayatri Singh, Kavita Dorai, Arvind
We experimentally demonstrate the transfer of an unknown single-qubit state from Alice to Bob via a two-step discrete-time quantum random walk on a cycle with four vertices on a fo…
