Harnessing subspace controllability: Dynamical generation of Dicke states in Heisenberg-coupled qubit arrays with a single local control
Vladimir M. Stojanovic, Tommaso Calarco, Andrea Muratori
We explore the feasibility of realizing Dicke states in qubit arrays with always-on isotropic Heisenberg coupling between adjacent qubits, assuming a single Zeeman-type control act…
Enhanced shortcuts to adiabaticity for coherent atom transport in a family of two-dimensional dynamical optical lattices
Sascha H. Hauck, Vladimir M. Stojanovic
In view of the compelling need for coherent atom transport as a prerequisite for a variety of emerging quantum technologies, we investigate such transport on the example of an adju…
- and Dicke-state engineering using optimal global control in nearest-neighbor coupled ring-shaped qubit arrays
Andrea Muratori, Vladimir M. Stojanovic, Eloisa Cuestas +2
Motivated by a compelling need for time-efficient and robust schemes for quantum-state engineering in systems of neutral atoms in optical tweezers, we consider a ring-shaped array…
Analog quantum simulation of small-polaron physics in arrays of neutral atoms with Rydberg-dressed resonant dipole-dipole interaction
Vladimir M. Stojanovic
Recent years have seen growing interest in sharp polaronic transitions in systems with strongly momentum-dependent interactions of an itinerant excitation (electron, hole, exciton)…
Quantum circuits for digital quantum simulation of nonlocal electron-phonon coupling
Vladimir M. Stojanovic
Motivated by the compelling need to understand the nonequilibrium dynamics of small-polaron formation following an electron-phonon interaction quench, in this work we propose a dig…
Twist-and-turn dynamics of spin squeezing in bosonic Josephson junctions: Enhanced shortcuts-to-adiabaticity approach
Manuel Odelli, Andreas Ruschhaupt, Vladimir M. Stojanovic
The twist-and-turn dynamics of spin squeezing results from the interplay of the one-axis-twisting (nonlinear in the collective-spin operators) and the transverse-field turning (lin…
