Hierarchy of quantum correlations in qubit-qutrit axially symmetric states
Venkat Abhignan, R. Muthuganesan
We investigate quantum correlations in a hybrid qubit-qutrit system subject to both axial and planar single-ion anisotropies, dipolar spin-spin interactions, and Dzyaloshinskii-Mor…
Resource Estimation for VQE on Small Molecules: Impact of Fermion Mappings and Hamiltonian Reductions
Anurag K. S. V., Ashish Kumar Patra, Vikas Dattatraya Ghevade +5
Accurate determination of ground-state energies for molecules remains a challenge in quantum chemistry and a cornerstone for progress in fields such as drug discovery and materials…
Approaching the scaling limit of transport through lattices with dephasing
Subhajit Sarkar, Gabriela Wójtowicz, Bartłomiej Gardas +2
We examine the stationary--state equations for lattices with generalized Markovian dephasing and relaxation. When the Hamiltonian is quadratic, the single--particle correlation mat…
Enhancing the Charging Performance of Many-Body Quantum Batteries through Landau-Zener Driving
Syed Abubacker Siddique, Md. Manirul Ali, Arijit Sen
We explore the charging advantages of a many-body quantum battery driven by a Landau-Zener field. Such a system may be modeled as a Heisenberg XY spin chain with inter…
Time Crystals from single-molecule magnet arrays
Subhajit Sarkar, Yonatan Dubi
Time crystals, a unique non-equilibrium quantum phenomenon with promising applications in current quantum technologies, mark a significant advance in quantum mechanics. Although tr…
Quantumness of electron transport in quantum dot devices through Leggett-Garg inequalities: A non-equilibrium Green's function approach
Thingujam Yaiphalemba Meitei, Saikumar Krithivasan, Arijit Sen +1
Although coherent manipulation of electronic states can be achieved in quantum dot (QD) devices by harnessing nanofabrication tools, it is often hard to fathom the extent to which…
