NMR studies of quantum chaos in a two-qubit kicked top
V R Krithika, V S Anjusha, Udaysinh T. Bhosale +1
Quantum chaotic kicked top model is implemented experimentally in a two qubit system comprising of a pair of spin-1/2 nuclei using Nuclear Magnetic Resonance techniques. The essent…
Path integrals, spontaneous localisation, and the classical limit
Bhavya Bhatt, Manish Ram Chander, Raj Patil +3
We recall that in order to obtain the classical limit of quantum mechanics one needs to take the limit. In addition, one also needs an explanation for the abse…
Periodicity of quantum correlations in the quantum kicked top
Udaysinh T. Bhosale, M. S. Santhanam
Quantum kicked top is a fundamental model for time-dependent, chaotic Hamiltonian system and has been realized in experiments as well. As the quantum kicked top can be represented…
Higher order spacing ratios in random matrix theory and complex quantum systems
S. Harshini Tekur, Udaysinh T. Bhosale, M. S. Santhanam
The distribution of the ratios of nearest neighbor level spacings has become a popular indicator of spectral fluctuations in complex quantum systems like interacting many-body loca…
Experimental emulation of quantum non-Markovian dynamics and coherence protection in the presence of information backflow
Deepak Khurana, Bijay Kumar Agarwalla, T. S. Mahesh
We experimentally emulate, in a controlled fashion, the non-Markovian dynamics of a pure dephasing spin-boson model at zero temperature. Specifically, we use a randomized set of ex…
Optimized dynamical protection of nonclassical correlation in a quantum algorithm
V. S. Anjusha, T. S. Mahesh
A quantum memory interacts with its environment and loses information via decoherence as well as incoherence. A robust quantum control that prepares, preserves, and manipulates non…
Ancilla Induced Amplification of Quantum Fisher Information
C. S. Sudheer Kumar, T. S. Mahesh
Given a quantum state with an unknown parameter, the Quantum Fisher Information (QFI) is a measure of the amount of information that an observable can extract about the parameter.…
Exact distribution of spacing ratios for random and localized states in quantum chaotic systems
S. Harshini Tekur, Santosh Kumar, M. S. Santhanam
Typical eigenstates of quantum systems, whose classical limit is chaotic, are well approximated as random states. Corresponding eigenvalue spectra is modeled through appropriate en…
