Chaos-Mediated Quantum State Discrimination Near Unit Fidelity
Sourav Paul, Anant Vijay Varma, Yogesh N. Joglekar +1
We investigate a ''quantum microscope'' for qubits based on nonlinear discrete-time chaotic dynamics, which exponentially amplifies the initially small fidelity of a pair of states…
Many-body adiabatic passage: Instability, chaos, and quantum classical correspondence
Anant Vijay Varma, Amichay Vardi, Doron Cohen
Adiabatic passage in systems of interacting bosons is substantially affected by interactions and inter-particle entanglement. We consider STIRAP-like schemes in Bose-Hubbard chains…
Characterization of hybrid quantum eigenstates in systems with mixed classical phasespace
Anant Vijay Varma, Amichay Vardi, Doron Cohen
Generic low-dimensional Hamiltonian systems feature a structured, mixed classical phase-space. The traditional Percival classification of quantum spectra into regular states suppor…
Fractional Conformal Map, Qubit Dynamics and the Leggett-Garg Inequality
Sourav Paul, Anant Vijay Varma, Sourin Das
Any pure state of a qubit can be geometrically represented as a point on the extended complex plane through stereographic projection. By employing successive conformal maps on the…
