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 ... -
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 ...
