Learning the eigenstructure of quantum dynamics using classical shadows
Atithi Acharya, Siddhartha Saha, Shagesh Sridharan +2
Learning dynamics from repeated observation of the time evolution of an open quantum system, namely, the problem of quantum process tomography is an important task. This task is di…
Informationally complete POVM-based shadow tomography
Atithi Acharya, Siddhartha Saha, Anirvan M. Sengupta
Recently introduced shadow tomography protocols use classical shadows of quantum states to predict many target functions of an unknown quantum state. Unlike full quantum state tomo…
Strongly interacting spin-orbit coupled Bose-Einstein condensates in one dimension
Siddhartha Saha, E. J. König, Junhyun Lee +1
We theoretically study dilute superfluidity of spin-1 bosons with antiferromagnetic interactions and synthetic spin-orbit coupling (SOC) in a one-dimensional lattice. Employing a c…
Generating end modes in a superconducting wire by periodic driving of the hopping
Siddhartha Saha, Shankar N. Sivarajan, Diptiman Sen
We show that harmonic driving of either the magnitude or the phase of the nearest-neighbor hopping amplitude in a p-wave superconducting wire can generate modes localized near the…
