Quantifying quantumness via commutators: an application to quantum walk
Pavan Iyengar, G. N. Chandan, R. Srikanth
The question of witnessing or quantifying nonclassicality of quantum systems has been addressed in various ways. For a given system or theory, we propose identifying it with the in…
Unification of Bell, Leggett-Garg and Kochen-Specker inequalities: A hybrid spatio-temporal inequality
Siddhartha Das, S. Aravinda, R. Srikanth +1
The Bell-type (spatial), Kochen-Specker (contextuality) or Leggett-Garg (temporal) inequalities are based on classically plausible but otherwise quite distinct assumptions. For any…
Simulation of mirror inversion of quantum states in an XY spin chain using NMR
K. Rama Koteswara Rao, T. S. Mahesh, Anil Kumar
We report an experimental quantum simulation of unitary dynamics of an XY spin chain with pre-engineered couplings. Using this simulation, we demonstrate the mirror inversion of qu…
Quantum simulations of a particle in one-dimensional potentials using NMR
Ravi Shankar, Swathi S. Hegde, T. S. Mahesh
A classical computer simulating Schrodinger dynamics of a quantum system requires resources which scale exponentially with the size of the system, and is regarded as inefficient fo…
Freezing a Quantum Magnet by Repeated Quantum Interference: An Experimental Realization
Swathi S. Hegde, Hemant Katiyar, T. S. Mahesh +1
We experimentally demonstrate the phenomenon of dynamical many-body freezing in a periodically driven Ising chain. Theoretically [Phys. Rev. B 82, 172402 (2010)], for certain value…
Inversion of moments to retrieve joint probabilities in quantum sequential measurements
H. S. Karthik, Hemant Katiyar, Abhishek Shukla +3
A sequence of moments encode the corresponding probability distribution. Probing if quantum joint probability distribution can be retrieved from the associated set of moments -- re…
The Scattering amplitude for one parameter family of shape invariant potentials related to Xm Jacobi polynomials
Rajesh Kumar Yadav, Avinash Khare, Bhabani Prasad Mandala
We consider the recently discovered, one parameter family of exactly solvable shape invariant potentials which are isospectral to the generalized Pöschl-Teller potential. By explic…
Monogamy of quantum correlations reveals frustration in a quantum Ising spin system: Experimental demonstration
K. Rama Koteswara Rao, Hemant Katiyar, T. S. Mahesh +3
We report a nuclear magnetic resonance experiment, which simulates the quantum transverse Ising spin system in a triangular configuration and further show that the monogamy of quan…
