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…
Nonlinear dynamics of Rydberg-dressed Bose-Einstein condensates in a triple-well potential
Gary McCormack, Rejish Nath, Weibin Li
We study nonlinear dynamics of Rydberg-dressed Bose-Einstein condensates (BECs) trapped in a triple-well potential in the semiclassical limit. The Rydberg-dressed BECs experience a…
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…
Tayloring Bose-Einstein condensate environments for a Rydberg impurity
S. Rammohan, A. K. Chauhan, R. Nath +2
Experiments have demonstrated that atoms excited to specific Rydberg states within Bose-Einstein condensates cause significant excitation of phonons. If the Rydberg atom is brought…
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…
Dynamics of Rydberg excitations and quantum correlations in an atomic array coupled to a photonic crystal waveguide
Yashwant Chougale, Jugal Talukdar, Tomás Ramos +1
We study the dynamics of up to two Rydberg excitations and the correlation growth in a chain of atoms coupled to a photonic crystal waveguide. In this setup, an excitation can hop…
