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…
Estimation of Wigner distribution of single mode Gaussian states: a comparative study
Chandan Kumar, Arvind
In this work, we consider the estimation of single mode Gaussian states using four different measurement schemes namely: i) homodyne measurement, ii) sequential measurement, iii) A…
Efficient experimental characterization of quantum processes via compressed sensing on an NMR quantum processor
Akshay Gaikwad, Arvind, Kavita Dorai
We employ the compressed sensing (CS) algorithm and a heavily reduced data set to experimentally perform true quantum process tomography (QPT) on an NMR quantum processor. We obtai…
Implementing efficient selective quantum process tomography of superconducting quantum gates on the IBM quantum processor
Akshay Gaikwad, Krishna Shende, Arvind +1
The experimental implementation of selective quantum process tomography (SQPT) involves computing individual elements of the process matrix with the help of a special set of states…
Implementation of discrete positive operator valued measures on linear optical systems using cosine-sine decomposition
Jaskaran Singh, Arvind, Sandeep K. Goyal
Positive operator valued measurements (POVMs) play an important role in efficient quantum communication and computation. While optical systems are one of the strongest candidates f…
Revealing quantum contextuality using a single measurement device
Jaskaran Singh, Rajendra Singh Bhati, Arvind
In this work we analyse the notion of measurement non-contextuality (MNC) and identify contextual scenarios which involve sequential measurements of only a single measurement devic…
