Determining the Number of Symmetry Sectors in Composite Quantum Spectra
Nisarg Vyas, S. Harshini Tekur, M. S. Santhanam
The spectral fluctuations in complex quantum systems are modeled in terms of spectra from random matrices. Quantitative agreement with random matrices holds only when the quantum s…
Quantum resonance based encryption protocol with quantum kicked top
Sreeram PG, M. S. Santhanam
We propose a genuine quantum protocol for protecting user's data, either in a shared quantum computer or in a quantum communication system, that is not accessible even to the servi…
Probing Chaos and Criticality with Observational Entropy and Finite-Resolution Measurements
J. Bharathi Kannan, Sreeram PG, M. S. Santhanam
Coarse-grained measurements offer a scalable alternative to full state tomography for characterizing complex quantum dynamics. We show that observational entropy (OE), an informati…
Localization with Hopping Disorder in a Quasiperiodic Synthetic Momentum Lattice
Joel M. Sunil, J. Bharathi Kannan, Monu Bhartiya +5
Quasiperiodicity is easily realized with ultracold atoms in optical lattices and has been used to simulate the delocalization-localization transition. Random local potentials can a…
