Coherent population trapping with a controlled dissipation: applications in optical metrology
(IOP PUBLISHING LTD, 2018)
We analyze the properties of a pulsed coherent population trapping protocol that uses a controlled decay from the excited state in a Lambda-level scheme. We study this problem analytically and numerically and find regimes ...
Optical qubit generation via atomic postselection in a Ramsey interferometer
(IOP PUBLISHING LTD, 2018)
We propose a realizable experimental scheme to prepare a superposition of the vacuum and one-photon states using a typical cavity QED-setup. This is different from previous schemes, where the superposition state of the ...
Nutrient Transport Driven by Microbial Active Carpets
(AMER PHYSICAL SOC, 2018)
We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways to replenish nutrients that feed back into ...
Correlated dephasing noise in single-photon scattering
(IOP PUBLISHING LTD, 2018)
We develop a theoretical framework to describe the scattering of photons against a two-level quantum emitter with arbitrary correlated dephasing noise. This is particularly relevant to waveguide-QED setups with solid-state ...
