Joint parameters estimation in cubic tensor model
Sumit Mukherjee, Arnab Sen, Qiang Wu
We study joint parameter estimation from a single observation in high-dimensional Gibbs measures with cubic tensor interactions, motivated by dense ERGMs, arithmetic-progression mo…
Optimizing Oscilloscope based Acquisition for Pulsed Optically Detected Magnetic Resonance Measurements
Anuvab Nandi, Sayan Chakraborty, Yashvardhan Jain +6
Ensembles of nitrogen vacancy (NV) defect centers in diamond have emerged as a promising platform for fundamental studies and applications in quantum sensing and quantum informatio…
A Mean Field Approach to Empirical Bayes Estimation in High-dimensional Linear Regression
Sumit Mukherjee, Bodhisattva Sen, Subhabrata Sen
We study empirical Bayes estimation in high-dimensional linear regression. To facilitate computationally efficient estimation of the underlying prior, we adopt a variational empiri…
Intraparticle entanglement-based Random Access Code protocols: Contextuality-enabled quantum advantage and implications
Nilaj Saha, Sumit Mukherjee, Dipankar Home
We provide the first explicit identification and quantitative characterization of the physical origin of the quantum advantage in the Random Access Code (RAC) protocol. This is ach…
Fluctuations in random field Ising models
Seunghyun Lee, Nabarun Deb, Sumit Mukherjee
This paper establishes a CLT for linear statistics of the form with quantitative Berry-Esseen bounds, where is an observa…
Connection between the contextuality breaking and incompatibility breaking qubit channels
Swati Kumari, Sumit Mukherjee, R. Prabhu
Contextuality and measurement incompatibility are two fundamental aspects of nonclassicality, and their manifestations in observed quantum correlations are often deeply interconnec…
