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 ... -
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 ... -
Fast High-Fidelity Quantum Nondemolition Qubit Readout via a Nonperturbative Cross-Kerr Coupling
(AMER PHYSICAL SOC, 2020)Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a nonperturbative cross-Kerr couplingbetween a transmon and polariton mode which enables an improved ... -
Intensity enhancement of ferromagnetic resonance modes in exchange coupled magnetic multilayers
(IOP PUBLISHING LTD, 2020)In this work, the ferromagnetic resonance characteristics of a NiFeCu/Non-magnetic(NM)/NiFe/NM/CoFe/NM/Co multilayer is studied from a theoretical point of view, and comparisons with the ferromagnetic resonance of a ... -
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 ... -
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 ... -
Quantum Discord, Thermal Discord, and Entropy Generation in the Minimum Error Discrimination Strategy
(MDPI, 2019)We study the classical and quantum correlations in the minimum error discrimination (ME) of two non-orthogonal pure quantum states. In particular, we consider quantum discord, thermal discord and entropy generation. We ...
