Maximally entangled Rydberg-atom pairs via Landau-Zener sweeps
Dhiya Varghese, Sebastian Wüster, Weibin Li +1
We analyze the formation of maximally entangled Rydberg atom pairs subjected to Landau-Zener sweeps of the atom-light detuning. Though the populations reach a steady value at longe…
Imaging the interface of a qubit and its quantum-many-body environment
S. Rammohan, S. Tiwari, A. Mishra +5
Decoherence affects all quantum systems, natural or artificial, and is the primary obstacle impeding quantum technologies. We show theoretically that for a Rydberg qubit in a Bose…
Population trapping in a pair of periodically driven Rydberg atoms
S. Kumar Mallavarapu, Ankita Niranjan, Weibin Li +2
We study the population trapping extensively in a periodically driven Rydberg pair. The periodic modulation of the atom-light detuning effectively suppresses the Rabi couplings and…
Observation of interaction induced blockade and local spin freezing in a NMR quantum simulator
V. R. Krithika, Soham Pal, Rejish Nath +1
We experimentally emulate interaction induced blockade and local spin freezing in two and three qubit Nuclear Magnetic Resonance (NMR) architecture. These phenomena are identical t…
Landau-Zener transitions and Adiabatic impulse approximation in an array of two Rydberg atoms with time-dependent detuning
Ankita Niranjan, Weibin Li, Rejish Nath
We study the Landau-Zener (LZ) dynamics in a setup of two Rydberg atoms with time-dependent detuning, both linear and periodic, using both the exact numerical calculations as well…
Designing Frustrated Quantum Magnets with Laser-Dressed Rydberg Atoms
Alexander W. Glaetzle, Marcello Dalmonte, Rejish Nath +3
We show how a broad class of lattice spin-1/2 models with angular- and distance-dependent couplings can be realized with cold alkali atoms stored in optical or magnetic trap arrays…
