In-phase and antiphase dynamics of Rydberg atoms with distinguishable resonances

Inhomogeneity Enhanced Signatures of Electromagnetically Induced Transparency

“…Figures 3 and 5 demonstrate the emergence of the probe pulse rendering the medium transparent achieving Electromagnetically Induced Transparency. In addition, one witnesses probe pulse broadening by virtue of the inhomogeneity [11] in the medium as shown in fig. 5.…”

“…Most of the investigations on EIT and other coherent processes in atomic ensembles have been conducted in gaseous media [10]. Fan et al investigated EIT experimentally in two different solid-state systems [11]. They noticed that, unlike numerous setups in uniformly broadened media, these systems displayed non-uniform broadening of their optical and spin transitions, which is characteristic of solid-state materials.…”

One-Step Implementation of Collective Anti-Blockade in a Rydberg Ring

“…So far, two methods of Rydberg anti-blockade have been proposed: one is the simultaneous driving [18,19] where a coherent field is suitably detuned to compensate for the (average) Rydberg shift so as to realize collective excitations of all atoms from the ground state to the Rydberg state; another is the sequential driving [20] where a first coherent field resonantly excites one atom to a Rydberg state while a second coherent field excites other atoms to the same state by compensating for the (average) Rydberg shift with a suitable detuning. There have been extensive studies on the realization and application of the Rydberg anti-blockade for atomic pairs or ensembles [21][22][23][24][25][26][27][28][29][30][31], while little attention has been paid to regularly arranged finite atoms, e.g., in a ring or a square optical lattice.…”

Atomic interactions for qubit-error compensations

“…The control of the wavefunction phase accumulation has received much attention in different contexts, such as the collapse and subsequent revival of atomic coherence for Bose-Einstein condensates in [31,32]. Phase correlation destructions and revivals in the time evolution of dipoleblockaded Rydberg states have been investigated under continuous detuned excitation in [14], and for periodic excitation by [15] within the context of discrete time crystals. The quantum control of the phase accumulated by laser driving for interacting Rydberg atoms was studied in [7,8].…”
