Ancilla mediated qubit readout and heralded entanglement between rare-earth dopant ions in crystals
Kamanasish Debnath, Alexander Holm Kiilerich, Klaus Mølmer
Owing to their long excited state lifetimes, rare-earth ions in crystals are widely used in quantum applications. To allow optical readout of the qubit state of individual ions, we…
Self-stimulated pulse echo trains from inhomogeneously broadened spin ensembles
Kamanasish Debnath, Gavin Dold, John J. L. Morton +1
We show experimentally and describe theoretically how a conventional magnetic resonance Hahn echo sequence can lead to a self-stimulated pulse echo train when an inhomogeneously br…
Collective dynamics of inhomogeneously broadened emitters coupled to an optical cavity with narrow linewidth
Kamanasish Debnath, Yuan Zhang, Klaus Mølmer
We study collective effects in an inhomogeneously broadened ensemble of two-level emitters coupled to an optical cavity with narrow linewidth. Using second order mean field theory…
Coherent spectral hole burning and qubit isolation by stimulated Raman adiabatic passage
Kamanasish Debnath, Alexander Holm Kiilerich, Albert Benseny +1
We describe how stimulated Raman adiabatic passage (STIRAP) can be applied to create spectral holes in an inhomogeneously broadened system. Due to the robustness of STIRAP, our pro…
Lasing in the superradiant crossover regime
Kamanasish Debnath, Yuan Zhang, Klaus Mølmer
A new class of laser, which harnesses coherence in both light and atoms, is possible with the use of ultra-cold alkaline earth atoms trapped in an optical lattice inside an optical…
Nonequilibrium photonic transport and phase transition in an array of optical cavities
Kamanasish Debnath, Eduardo Mascarenhas, Vincenzo Savona
We characterize photonic transport in a boundary driven array of nonlinear optical cavities. We find that the output field suddenly drops when the chain length is increased beyond…
