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 ...
